The range of medicines included in this formulary is intended to encourage safe, effective and economical prescribing. These medicines are routinely available to prescribe on EP, but use of some may be restricted. Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the British National Formulary (BNF). Recommended International Non-proprietary Names (INNs) are used throughout the text, but proprietary names are used for some combination and modified release products where brand name prescribing is recommended, or to clarify which product is listed. Products listed in the formulary alphabetically with no ranking unless specified in the text. Products are flagged to indicate if they are hospital only products, suitable for shared care, are unlicensed or have been approved for an unlicensed indication. Hospital doctors should not ask GPs to prescribe hospital only medicines (‘Red’ drugs) unless there is a very exceptional reason and agreement with the GP. When prescribing unlicensed medicines it is important that prescribers are aware that they are taking on additional responsibilities regarding the patient’s safety. NAVIGATION AROUND THE GUIDE Medicines are listed alphabetically in chapters and subsections that generally correspond with those in the British National Formulary (BNF). Specific drugs can be searched by using the Find function (Ctrl+F). PRESCRIBING NON-FORMULARY DRUGS For hospital-initiated therapy or patients admitted on non-formulary drugs, prescribers are requested to choose, or change to, drugs included in the formulary as far as possible. On EP, non-formulary drugs are pre-fixed with the character ~ (tilde), e.g. ~rabeprazole. Consequently, these drugs are not available on normal drug lists. In order to view and prescribe on EP, enter ~ before the drug name. When initiating a non-formulary drug, the form APPLICATION FOR THE REQUEST OF A NON-FORMULARY DRUG FOR A SPECIFIC PATIENT must be completed. Forms are available on the Intranet: Drugs and Therapeutics Group. Multiple requests for the same drug from the same consultant will be queried and, if necessary, supply may be refused. In such circumstances, a formal request to the Drugs and Therapeutics Group for inclusion in the Formulary IS necessary. The patient's own supply may be used however (but must still be prescribed on EP). Before prescribing, prescribers must ensure that sufficient is available for the admission and discharge. City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 2 Please note: The Pharmacy Department has been given the authority to query prescriptions for non-formulary items. Non-formulary drugs will be supplied only in exceptional cases, when all alternatives have been tried and failed, or when there is no alternative. There may be a delay (up to 48 hours) in obtaining non-formulary drugs, as these are not routinely held in stock. Supply is considered to be a ‘one-off’ and is only for the specific patient named on the form. Stock will not be held in pharmacy. The use of non-formulary drugs will be monitored and use will be reported back to the relevant Directorate. UNLICENSED MEDICINES AND USE OF MEDICINES FOR UNLICENSED INDICATIONS This formulary contains a number of unlicensed medicines, and medicines that have been approved for unlicensed or ‘off-label’ indications. Many unlicensed medicines are formulations of well established drugs that are included the BNF, whereas others are products that are less well known, but considered to be of benefit in the treatment of patients with conditions where licensed medicines cannot be used or fail to produce an adequate response. Unlicensed medicines included in the Formulary are marked using the notation U, and that are considered unsuitable for prescribing by GPs (even if treatment has been started and stabilised by a hospital clinician) are classified as ‘RED’, or hospital only, medicines. When prescribing an unlicensed or a licensed product ‘off-label’ for an unlicensed indication it is important prescribers are aware that it is not only they who take on additional responsibilities regarding the patient’s safety and welfare, but the burden is shared with others involved in supply and administration. While further information and guidance can be obtained from the Intranet, prescribers are reminded that when prescribing unlicensed or off-label licensed products: The clinical and/or pharmaceutical benefits, not cost, must outweigh the potential risks of treatment and be justifiable. They should not be used if there is an equally appropriate licensed medicine that would meet the patient's needs. Patients, their carers and/or healthcare staff should be given sufficient information to use the product correctly and safely (manufacturer’s information leaflets may not be adequate when a medicine is used for an unlicensed indication). City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 3 Where common practice is not being followed, the reasons for prescribing the medicine should be recorded. Documented patient consent should be obtained in high-risk situations. NICE GUIDANCE Where appropriate, the Formulary will list important and relevant NICE Clinical Guidance (CG) A list of published Clinical Guidelines by NICE, which is searchable, can be found on the NICE website: http://guidance.nice.org.uk/CG/Published. NICE technology appraisal recommendations are reviewed on a regular basis. Where a NICE technology appraisal states ‘option for treatment’, assessment is made of its place in a treatment pathway. All decisions are ratified by the local formulary and decision-making groups, which are then incorporated in the Formulary. A list of published Technical Appraisals by NICE, which is searchable, can be found on the NICE website: http://www.nice.org.uk/Guidance/TA/Published Alternatively, a table of all the TA recommendations can be viewed or printed as a Word document: Full table of TA recommendations. ESTIMATION OF RENAL IMPAIRMENT AND DRUG DOSING Renal function in adults is routinely reported on the basis of estimated glomerular filtration rate (eGFR), which is normalised to a body surface area of 1.73 m2 and derived from the Modification of Diet in Renal Disease (MDRD) formula. It is calculated using serum creatinine concentration, age, sex and ethnic origin. Published information on the effects of renal impairment on drug elimination is usually stated in terms of creatinine clearance (CrCl) – based on the Cockcroft & Gault (C&G) estimation - as a substitute for glomerular filtration rate (GFR). Although the two measures of renal function are not interchangeable, in practice, for most drugs and for most patients (over 18 years) of average build and height, eGFR (MDRD) can be used to determine dosage adjustments in place of CrCl (C&G). The information on dosage adjustment in the BNF is usually expressed as eGFR as opposed to CrCl, and this can be used for a large number of drugs and patients. However, there are exceptions where the absolute GFR or CrCl calculated by the C&G formula should be used: Patients at extremes of body weight (BMI <18.5 Kg/m2 or >30 Kg/m2). If using absolute GFR for these patients it may be necessary to base the calculation on ideal body weight. Children under 18 years Potentially toxic drugs with a narrow therapeutic index. In the BNF, values for creatinine clearance or another measure of renal function are included where possible. City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 4 An individual's absolute glomerular filtration rate can be calculated from the eGFR as follows: GFR Absolute = eGFR × (individual's body surface area/1.73) The BNF is generally not a good resource for patients with renal impairment. It does not make a distinction between steady-state chronic kidney disease (CKD) and acute kidney injury (AKI). The Renal Drug Handbook is a more useful guide, although the emphasis is largely on the word “guide”, for making dose adjustments in patients with AKI, where GFR may be changing rapidly. Clinical interpretation is necessary.

Specific drugs can be searched by using the Find function (Ctrl+F). 2.1 POSITIVE INOTROPIC DRUGS Adults - see BNF for further information Children – see BNFC for further information 2.1.1 Digoxin Care with digoxin is recommended because it has a narrow therapeutic index and therefore should be used with caution in the elderly and in renal impairment. Regular measurements of plasma digoxin concentrations are not usually necessary except to confirm toxic or sub-therapeutic levels, or to check compliance. Loading Doses The National Patient Safety Agency (NPSA) issued an alert regarding the administration of loading doses in November 2010: Preventing fatalities from medication loading doses. A loading dose may be given on initiation of therapy to achieve a rapid therapeutic effect; otherwise, it will take about a week to obtain maximal effect. Care must be taken when prescribing and administering digoxin for rapid digitalisation – usually given orally for no longer than 24 hours. Very rarely should it be necessary to use the intravenous route and should only be undertaken with Specialist advice. . Intramuscular injection should be avoided as it is painful and absorption is variable Doses of digoxin greater than 250 microgram once daily in adults and greater than 125 microgram in people over 70 years of age should rarely be seen. Hypokalaemia and Electrolyte Disturbances Hypokalaemia can increase tissue sensitivity to digoxin, and is one of the most common factors for adverse effects. Careful monitoring of potassium levels is recommended. If potassium levels are low, digoxin toxicity can be assumed without waiting for digoxin levels. Hypercalcaemia and hypomagnesaemia may also be associated with increased tissue sensitivity to digoxin. See Therapeutic Drug Monitoring for advice on monitoring, pharmacokinetics, interactions and equivalences Digoxin Injection: 500 micrograms/2 mL PLiquid: 50 micrograms/1 mL PTablets: 62.5 micrograms, 125 micrograms, 250 micrograms City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 23 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

Specific drugs can be searched by using the Find function (Ctrl+F). 2.2 DIURETICS Adults - see BNF for further information Children – see BNFC for further information General Points Regular review of diuretic use is desirable to confirm continued need and to monitor adverse effects such as dehydration, which may cause renal impairment (particularly in the elderly). Thiazide diuretics may increase lithium levels to a dangerous extent and should be avoided in patients on lithium therapy. Hypokalaemia Thiazide and loop diuretics cause serum-potassium levels to fall particularly during the first few weeks of treatment. Drugs with a long duration of action tend to have the most pronounced effect. Routine use of potassium supplements is not necessary. Potassium supplements are seldom required with the small doses of diuretics given to treat hypertension; potassium-sparing diuretics (rather than potassium supplements) are recommended for prevention of hypokalaemia due to diuretics such as furosemide or the thiazides when these are given to eliminate oedema. Individual patients’ requirements for potassium supplements or potassiumsparing diuretics should be re-assessed regularly by measuring serumpotassium levels. 2.2.1 Thiazides and related diuretics PBendroflumethiazide Tablets: 2.5 mg, 5 mg PIndapamide Tablets: 2.5 mg PMetalazone Tablets: 5 mg City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 25 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

Specific drugs can be searched by using the Find function (Ctrl+F). 2.3 ANTI-ARRHYTHMIC DRUGS Adults - see BNF for further information Children – see BNFC for further information DRUGS IN THIS SECTION SHOULD ONLY BE USED WITH SPECIALIST ADVICE Loading Doses The National Patient Safety Agency (NPSA) issued an alert regarding the administration of loading doses in November 2010: Preventing fatalities from medication loading doses. Amiodarone has a very long half-life and many weeks or months may be required to achieve steady-state plasma-concentration. IV administration allows more rapid loading; if amiodarone has already been given as an IV infusion, the oral loading dose may need to be reduced depending on the length of the infusion. Intervals of at least 6-8 weeks should be allowed to assess the effect of dosage adjustments during long-term therapy. Its use is limited by potential multiple adverse drug reactions. Maintenance therapy should be undertaken only if necessary because of longterm side effects; the lowest effective dose should be used and careful follow up of patients is mandatory. Amiodarone doses higher than 200 mg daily should be queried (the maximum licensed dose for maintenance is 200 mg). See Trust guideines: Loading Doses Dronedarone The European Medicines Agency Committee for Medicinal Products for Human Use (CHMP) has assessed the benefits and risks - see the Summary of Product Characteristics (SPC) for further updated advice. It is now only indicated in adult clinically stable patients with paroxysmal or persistent atrial fibrillation (AF) for the maintenance of sinus rhythm after successful cardioversion. It is now contraindicated in patients with: o Unstable Haemodynamic conditions o History of, or current heart failure or left ventricular systolic dysfunction o Permanent AF (AF duration ≥ 6 months or unknown, and attempts to restore sinus rhythm no longer considered by the physician). o Liver and lung toxicity related to previous use of amiodarone. Patients should be carefully monitored during treatment by regular assessment of cardiac, hepatic and pulmonary function. Liver function tests (LFTs) should be measured before initiation, after one week and one month following initiation and then repeated monthly for six months, at months 9 and 12, and periodically thereafter. If the patient develops any condition that would be considered a contraindication, then treatment must be stopped.

Avoid abrupt withdrawal of beta-blockers; this should be done gradually over several weeks. Although not contraindicated, cardioselectivity is desirable in diabetes; avoid in those with frequent episodes of hypoglycaemia. Beta blockers, especially when combined with a thiazide diuretic, should be avoided for the routine treatment of uncomplicated hypertension in patients with diabetes or in those at high risk of developing diabetes. Caution in combination with calcium-channel blockers (such as diltiazem and verapamil) since depression of myocardial function and conduction may occur. Concurrent use of verapamil and beta-blockers is contraindicated.

Unfractionated Heparin (UFH) Heparin initiates anticoagulation rapidly but has a short duration of action. For patients at high risk of bleeding, heparin is more suitable than low molecular weight heparin because its effect can be terminated rapidly by stopping the infusion. A baseline FBC and PT and APTT should be measured in all patients prior to commencing Heparin. A standard preparation of 1000 units per mL will be used across the Trust for heparin infusions. Heparin infusions should be prescribed on E.P. for all areas that routinely use E.P. Paper heparin charts should no longer be used. The product for infusions is heparin sodium 20, 000 units as a 20 mL ampoule following a loading dose of 5,000 units IV (5 mL of 1,000 units per mL) APTT ratio should be ordered and checked according to the protocol overleaf. The person administering the heparin will be required to check the rate of the infusion four times a day and adjust it if necessary as per the protocol below. For areas that do not use EP, heparin 1,000 units/mL should be prescribed on the standard heparin chart according to the regime below. A FBC should be checked on day 5 and day 7 of Heparin infusions to exclude Heparin Induced Thrombocytopaenia (HITT). Heparin IV regime Available as an order set – Prescriber should enter Set then HeparinInf A Loading Dose of 5,000 units is prescribed as ONCE by IV bolus injection - [Heparin 5,000 units as a 5 mL ampoule (Concentration 1,000 units per mL). In addition a Regular Order will appear Heparin 20,000 units in 20 mL amp with dose Instructions (See Administration Criteria) administered as an IV Infusion. The administration criteria are automatically provided to the nurse but can be used by prescribers without EP on standard heparin charts.

Starting rate (dose) < 40kg then 0.8 mL (800 units) per hour 41 - 60kg 1 mL (1,000units) per hour 61 - 80kg 1.3 mL (1,300 units) per hour 81 - 100kg 1.6 mL (1,600 units) per hour >100kg 2 mL (2,000 units) per hour Order and arrange check of APTT ratio after 4 to 6 hours If adjustment to the dosage of heparin sodium infusion 1000 units per mL is need to bring APTT ratio into range the following infusion rate change is advised. (Note ideally aim for low end of range for AF/mural thrombi and higher end for prosthetic mitral values). If APTT ratio fluctuates widely seek Haematologist advice. APTT Ratio >7 5.1 – 7.0 4.1 – 5.0 3.3 – 4.0 1.8 – 3.2 1.4 – 1.7 1.0 – 1.4 ACTION Stop infusion for 1 hour, check APTT ratio is falling before reducing rate by 0.7 mL (700 units) per hour Reduce by 0.5 mL (500 units) per hour Reduce by 0.3 mL (300 units) per hour Reduce by 0.1 mL (100 units) per hour No change Increase by 0.1 mL (100 units) per hour Increase by 0.3 mL (300 units) per hour Check APTT ratio After a further 2 hours After 4 hours After 6 hours After 12 hours After 24 hours After 12 hours After 4 hours This regime uses 1,000 units per mL heparin, which is double the strength of the previous regime if prescribing on paper please check documentation. Please Note - The Electronic Prescription system will display the last APTT ratio measured at the point of prescribing (likely to be no result). When full documenting (FD) on administration (fixed as four times a day) the last APTT ratio will be also be displayed and the rate should be confirmed as appropriate by the nurse and recorded. Low Molecular Weight Heparins (LMWH) Low molecular weight heparins are as effective and safe as unfractionated heparin, and appear to be more effective in orthopaedic surgery. They are advantageous in that only one subcutaneous injection is required daily, instead of two or three with conventional heparin. No monitoring is required for prophylaxis. Monitoring may be necessary in patients at increased risk of bleeding (e.g. in renal impairment and those who are underweight or overweight); they can be given by subcutaneous injection; and have less incidence of heparin induced thrombocytopenia (HIT). City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 38 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). Dalteparin Prophylaxis Dosing (1) Dalteparin is the LMWH used at CHS except in Trauma and Orthopaedics where enoxaparin is used. Standard dose of dalteparin 5,000 Units given once daily by subcutaneous injection for surgical patients (enoxaparin 40 mg for Trauma and Orthopaedic patients). Treatment Dosing and Monitoring (2) This must be prescribed on E.P. Treatment of venous thromboembolism (VTE). - dalteparin is usually given once daily by subcutaneous injection based on bodyweight (200 IU/kg). For patients with an increased risk of bleeding requiring treatment, it is recommended that dalteparin be administered according to the twice daily regimen. The single daily dose should not exceed 18,000 IU (but see below for advice on extremes of body weight). Please note dosing schedule is different in pregnancy. Caution in acute asthma. Adjust dose in severe renal impairment (see below for advice) Patient Weight < 46 kg 46 – 56 kg 57 – 68 kg 69 – 82 kg ≥ 83 kg Dose of Dalteparin 7,500 units 10,000 units 12,500 units 15,000 units See below Frequency SC once daily SC once daily SC once daily SC once daily SC once daily Monitoring of Anti-Xa Levels is not usually required but should be considered for specific patient populations such as paediatrics, those with renal failure, patients very thin or morbidly obese, pregnant or at increased risk for bleeding or rethrombosis. Doses should be adjusted accordingly. Dosing in Obese Patients There is, at present a lack of good evidence-based data to inform the prescribing of low molecular weight heparin for thromboprophylaxis or treatment in obese patients. Thromboprophylaxis In light of so little evidence, a pragmatic approach is to base increased prophylactic doses on weight. All obese patients should be classed as high risk for venous thromboembolism as they have at least one risk factor in addition to their City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 39 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). surgery/medical condition, therefore the available evidence points towards higher LMWH dosing in this patient group. (3) There is a dosing protocol for enoxaparin which has been extrapolated to dalteparin and the following are suggested doses for thromboprophylaxis. (3) Dalteparin < 50 kg 2,500 Units daily 50 – 100 kg 5,000 Units daily 100 – 150 kg 5,000 Units twice daily > 150 kg 7,500 Units twice daily Treatment Once again, there is little information as morbidly obese patients are excluded from clinical trials. The manufacturer of dalteparin (Fragmin®, Pfizer) recommends a dose of 200 units/kg (dose capped at 18,000 units). However, studies show that doses should not be capped and be based on actual body weight. (5-8) Doses should be given once a day; for patients weighing >120kg, a dose of 100 units/kg BD is suggested to reduce the risk of bleeding. Seek advice from a haematologist for patients weighing >190kg.and monitoring of anti-Xa levels is recommended. (6) Anti-Xa levels should be checked after every 3rd dose and after 10 days, or if actively bleeding. Take 4 hours post dose. This service is only available Monday to Friday. The Haematology lab should be contacted before sending the sample at weekends. Renal impairment and dosing (4) Low molecular weight heparins are renally excreted and hence accumulate in severe renal impairment. Dose adjustment is not necessary for prophylactic doses of dalteparin. However, the doses recommended for treatment of DVT and PE has been associated with severe, sometimes fatal, bleeding. In patients with acute kidney injury (AKI) please seek the advice of haematology or renal team. In patients with Chronic Kidney Disease (CKD) if GFR (Cockcroft-Gault) is 20 - 50 mL/min - normal dosing but review after 3 days, if still required switch to unfractionated heparin if GFR (Cockcroft-Gault) is < 20 mL/min – use unfractionated heparin In patients with GFR (Cockcroft-Gault) ≤ 30 mL/min, monitoring for anti-Xa levels is recommended to determine the appropriate dalteparin dose. Target anti- Xa range is 0.5-1.5 IU/m. City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 40 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). Anti-Xa levels should be checked after every 3rd dose and after 10 days, or if actively bleeding. Take 4 hours post dose. This service is only available Monday to Friday. The Haematology lab should be contacted before sending the sample at weekends. Frequency of administration Ideally, dalteparin should be given once every 24 hours at the same time each day. Less than 24 hours will mean that there is a risk of over-anticoagulation and more than 24 hours will mean that there is a risk of under-coagulation (i.e. sub-therapeutic levels). However, sometimes it is deemed necessary to change the timing of administration to coincide with community nurse visits. The manufacturer of dalteparin (Fragmin® – Pfizer) has stated that a delay of 1-2 hours would most probably not lead to any risk for the patient. (9) Pharmacy/Haematology/Renal May 2013 References 1.

See Drug Safety Update, January 2012 Fibrates should not be prescribed to newly diagnosed patients as first-line treatment, except for those with severe hypertriglyceridaemia or those who cannot take statins. See Drug Safety Update, December 2010 There is an increased risk of myopathy associated with high-dose (80 mg) simvastatin. The 80-mg dose should be considered only in patients with severe hypercholesterolaemia and high risk of cardiovascular complications who have not achieved their treatment goals on lower doses, when the benefits are expected to outweigh the potential risks. See Drug Safety Update, May 2010. In addition, the risk of myopathy is increased when administered with other medicines. See Drug Safety Update, August 2012.

Specific drugs can be searched by using the Find function (Ctrl+F). CHM advice To ensure safe use, the CHM has advised that for the management of chronic asthma, long-acting beta2 agonists (formoterol and salmeterol) should: be added only if regular use of standard-dose inhaled corticosteroids has failed to control asthma adequately; not be initiated in patients with rapidly deteriorating asthma; be introduced at a low dose and the effect properly monitored before considering dose increase; be discontinued in the absence of benefit; not be used for the relief of exercise-induced asthma symptoms unless regular inhaled corticosteroids are also used; be reviewed as clinically appropriate: stepping down therapy should be considered when good long-term asthma control has been achieved. Patients should be advised to report any deterioration in symptoms following initiation of treatment with a long-acting beta-2 agonist Generally, manually actuated pressurised metered dose inhalers (MDIs) are the cheapest devices available and should be first choice provided that the patient can use them efficiently. When use is inefficient, alternatives include large volume spacers, dry powder inhalers (DPIs) or breath-actuated MDIs. Choice of device should be considered on basis of ability to use the inhaler, patient-acceptability and cost. If a patient elects not to use a prescribed spacer, then an alternative device should be used. BTS/SIGN guidance for prescribing: There is no evidence to dictate an order in which devices should be tested for those patients who cannot use an MDI. In the absence of evidence, the most important points to consider are patient preference and local cost. o The choice of device may be determined by the choice of drug. o If the patient is unable to use a device satisfactorily, an alternative should be found. o The patient should have their ability to use an inhaler device assessed by a competent healthcare professional. o The medication needs to be titrated against clinical response to ensure optimum efficacy. o Reassess inhaler technique as part of structured clinical review. o In children aged 0-5 years, an MDI and spacer are the preferred method of delivery of beta-2 agonists or inhaled steroids. A face mask is required until the child can breathe reproducibly using the spacer mouthpiece. Where this is ineffective, a nebuliser may be required. Inhaler-induced cough by MDI may be an indicator for change of device. Changing the type of inhaler device may affect the effectiveness of therapy and the incidence of adverse effects.

It may have an additive effect when used in conjunction with small doses of beta-2 adrenoceptor stimulants: the combination may increase the risk of side effects e.g. hypokalaemia. Theophylline has a narrow margin between the therapeutic and toxic dose. The therapeutic range is 10 - 20 mg/L (55 - 110 micromol/L). There is wide interindividual variability in dosage requirements and therapy should be monitored. Ideally, therapy should be monitored after 2 weeks initially and then every 6 months Adult - see Therapeutic Drug Monitoring). Theophylline/aminophylline levels may be increased by a number of drugs including macrolide antibiotics, ciprofloxacin and verapamil. For more information on drug interactions see the BNF Concomitant disease and drugs may affect plasma levels Adult - see Therapeutic Drug Monitoring). Smoking cessation may increase theophylline levels; this is independent of any nicotine replacement therapies that may be prescribed. Different brands of modified-release theophylline have different bioavailability and so it is recommended that patients do not switch brands. The brand must be stated on prescriptions. Aminophylline is a stable mixture or combination of theophylline and ethylenediamine; the ethylenediamine confers greater solubility in water but can cause an allergic reaction. Aminophylline IV: Patients already taking oral theophylline or aminophylline should routinely not be given IV aminophylline unless plasma levels are available to guide dosing.

The choice of spacer depends upon the inhaler device and the patient’s ability to use it. Spacers are available from supplies (not pharmacy). The BNF lists currently available spacer devices and their compatibility with various inhalers. The BTS guidelines makes recommendations about the use and care of spacers: i. The spacer should be compatible with the MDI being used. ii. The drug should be administered by repeated single actuations of the metered dose inhaler into the spacer, each followed by inhalation. iii. There should be minimal delay between MDI actuation and inhalation. iv. Tidal breathing is as effective as single breaths. v. Spacers should be cleaned monthly rather than weekly as per manufacturer's recommendations or performance is adversely affected. They should be washed in detergent and allowed to dry in air. The mouthpiece should be wiped clean of detergent before use. vi. Drug delivery may vary significantly due to static charge. Metal and other antistatic spacers are not affected in this way. vii. Plastic spacers should be replaced at least every 12 months but some may need changing at six months.

Oxygen is a drug and should therefore be prescribed. Inappropriate concentrations may have serious or even lethal effects. Patients should be advised of the fire risks with oxygen and they or their contacts must not smoke in the same environment. The prescription should include the percentage of oxygen to be administered (24% - 100%), duration, whether continuous or as required, if humidification is indicated and delivery system i.e. specified mask type and flow rate. For nasal cannulae, the oxygen flow rate in L/minute should be specified. High concentration oxygen therapy (35%-100%) is used for short periods in cases of Type I Respiratory Failure (e.g. asthma, pulmonary embolism, pneumonia, congestive cardiac failure, and pulmonary fibrosis) where there is a combination of a low arterial oxygen and normal or low carbon dioxide concentration. Low concentration oxygen therapy (24% - 28%) is used for patients with Type II Respiratory Failure and is most commonly prescribed in chronic obstructive pulmonary disease (COPD).

Benzodiazepines are indicated for the short-term relief (two to four weeks only) of anxiety that is severe, disabling, or causing the patient unacceptable distress, occurring alone or in association with insomnia or short-term psychosomatic, organic, or psychotic illness. 2. The use of benzodiazepines to treat short-term ‘mild’ anxiety is inappropriate. 3. Benzodiazepines should be used to treat insomnia only when it is severe, disabling, or causing the patient extreme distress 4.1.1 Hypnotics Recommended: PTemazepam Tablets: 10 mg Elixir 10 mg/5 mL Alternative: PZopiclone Tablets: 3.75 mg, 7.5 mg 4.1.2 Anxiolytics Recommended: PDiazepam Tablets: 2 mg, 5 mg, 10 mg Syrup: 2 mg/5 mL, 5 mg/5 mL Alternative: PLorazepam Tablets: 1 mg, 2.5 mg City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 72 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

The commonly used preparations are routinely available, but it is possible that some of the rarely used preparations may not be immediately available and may have to be ordered. General Points Patients established on antipsychotic treatment should not have their medication changed or stopped (discontinuation of all antipsychotic treatment should be phased over a period of about four weeks). SEEK SPECIALIST ADVICE. The elderly are much more susceptible to the extrapyramidal side effects of antipsychotics, as well as to orthostatic hypotension and antimuscarinic effects of these agents. In addition, there is an increased risk of stroke and mortality when used in elderly people with dementia. When indicated, they should be used in much lower doses and titrated more slowly, with frequent monitoring. BNF advice on prescribing in the elderly is available HERE. For MHRA advice see Drug safety Update, March 2009 The MHRA issued a reminder to monitor and manage weight, glucose, and lipid levels in patients on second-generation (atypical) antipsychotic drugs. This is because people with schizophrenia are three times more likely to die prematurely from natural causes (mainly cardiovascular disease). Some atypical antipsychotics are associated with weight gain, dyslipidaemia, and hyperglycaemia (available data suggest that clozapine, olanzapine, and quetiapine are especially implicated). See Drug safety update, April 2011. Clozapine and lithium require monitoring and caution in their use. o Clozapine is reserved for individuals with evidence of treatment resistant schizophrenia (TRS). The patient, prescriber, and supplying pharmacist must be registered with the relevant Patient Monitoring Service. o Lithium preparations should always be prescribed by brand name because of major differences in bioavailability. o Lithium salts have a narrow therapeutic/toxic ratio and should therefore not be prescribed unless facilities for monitoring are available. For advice on monitoring, cautions and drug interactions see Therapeutic Drug Monitoring . o The National Patient Safety Agency (NPSA) has issued a safety alert in December 2009, see NPSA alert: Safer Lithium Therapy City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 74 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). Long acting antipsychotic depot injections are useful for maintenance therapy especially when compliance with oral treatment is unreliable. They are given by deep IM injection every 1 - 4 weeks for maintenance therapy and no more than 2 – 3 mL should be injected into any one site. They can cause more extrapyramidal reactions so treatment should be monitored carefully. During transfer from oral to depot therapy, the oral dose should be phased out gradually.

The commonly used preparations are routinely available, but it is possible that some of the rarely used preparations may not be immediately available and may have to be ordered. General Points Patients already taking medication for depression should not have their medication changed or stopped (discontinuation of all antidepressant treatment should be phased over a period of about four weeks). SEEK SPECIALIST ADVICE. NICE do not recommend the use antidepressants routinely to treat persistent subthreshold depressive symptoms or mild depression because the risk– benefit ratio is poor, SEEK SPECIALIST ADVICE. Hyponatraemia can occur with all antidepressants. It is most common in elderly patients. The use of antidepressants has been linked with suicidal thoughts and behaviour (particularly in children, young adults, and patients with a history of suicidal behaviour). Great care should be taken when prescribing any antidepressant for epileptic patients as they all lower the convulsive threshold. Treatment with more than one antidepressant of the same type is not recommended. All antidepressants have a potentially dangerous interaction with MAOIs - refer to the BNF. Antimuscarinic effects of tricyclic and related antidepressant drugs limit their use (particularly in the elderly). They should be used with caution in patients with cardiovascular disease and are contra-indicated in the immediate recovery period after myocardial infarction, in arrhythmias (particularly heart block), and in the manic phase of bipolar disorder. Avoid in acute porphyria. There is an increased risk of bleeding when SSRIs are given with NSAIDs or aspirin. If no alternatives are appropriate, NICE guidance recommends that gastroprotection is offered. Fluoxetine has an extremely long half-life and should be used with caution in the elderly.

Citalopram and dose dependant QT prolongation The MHRA have sent out an update regarding safety concerns with citalopram on 31st October 2011 following an FDA review of a recent unpublished study. New recommendations have been made as a result of a QT study which revealed a dosedependant increase in the QT interval New Recommendations Maximum dose of citalopram is now 40 mg daily In elderly and reduced hepatic function, the maximum dose is 20 mg daily Citalopram is now contra-indicated in patients with known QT interval prolongation or congenital long QT syndrome. Use of citalopram with other medicinal products known to prolong the QT interval is contraindicated. Caution is advised in patients at higher risk of developing Torsades de Pointes e.g. patients with congestive heart failure, recent MI, bradyarrhythmias or a predisposition to hypokalaemia or hypomagnesaemia because of concomitant illness or medicines. Citalopram oral drops have approximately 25% increased bioavailability compared to tablets. The tablet corresponds to the number of drops as follows: Tablets 10 mg 20 mg 30 mg 40 mg Drops dose equivalence 8 mg (4 drops) 16 mg (8 drops) 24 mg (12 drops) 32 mg (16 drops) The following are routinely stocked and available from pharmacy: PCitalopram Tablets: 10 mg, 20 mg Oral drops: 40 mg/ mL PFluoxetine Tablets: 20 mg Liquid: 20 mg/5 mL.

If treatment is indicated, then choice of drug depends upon the aetiology of vomiting. Nausea and vomiting associated with chemotherapy – see the North of England Cancer Network (NECN) Chemotherapy Induced Nausea and Vomiting (CINV) Guidelines: LINK Nausea and vomiting associated with palliative care – see the North of England Cancer Network (NECN) Palliative Care Guidelines LINK Sickness in pregnancy is best left untreated unless severe. Specialist advice should be sought before using an antiemetic in pregnancy. Metoclopramide: risk of neurologicaladverse effects - restricted dose and duration of use Indications and use in adults and children: In adults, metoclopramide remains indicated for: prevention of postoperative nausea and vomiting; radiotherapy-induced nausea and vomiting; delayed (but not acute) chemotherapy-induced nausea and vomiting; and symptomatic treatment of nausea and vomiting, including that associated with acute migraine (where it may also be used to improve absorption of oral analgesics) In children, age 1–18 years, metoclopramide should only be used as a second-line option for prevention of delayed chemotherapy-induced nausea and vomiting, and for treatment of established postoperative nausea and vomiting Use of metoclopramide is contraindicated in children younger than 1 year Metoclopramide should only be prescribed for short-term use (up to 5 days) Dosing: For adults, the maximum dose in 24 hours is 30 mg (or 0.5 mg per kg bodyweight). The usual dose is 10 mg up to three times a day In children age 1 year or older, the recommended dose is 0.1–0.15 mg per kg bodyweight, repeated up to three times a day. The maximum dose in 24 hours is 0.5 mg per kg bodyweight Administration: Intravenous doses should be administered as a slow bolus over at least 3 minutes to reduce the risk of adverse effects Oral liquid formulations should be given via an appropriately designed, graduated oral syringe to ensure dose accuracy in children.

The BNF states that the dose of IV paracetamol for adults and children between 1050 kg is 15 mg/kg every 4-6 hours up to a maximum of 60 mg/kg/daily. Please ensure that the weight of the patient is recorded on the front of the prescription chart. When prescribing IV paracetamol check the weight of the patient and reduce the dose in patients weighing less than 50 kg. See Drug Safety Update July 2010 for dosing and administration advice Paracetamol: New oral dosing recommendations for children Updated dosing for paediatric paracetamol liquids has been developed to ensure children receive the optimum dose for their age.

This may be done for example through discussion with the patient or their representative (although not in the case of treatment for addiction), the prescriber or through medication records. Ensure where a dose increase is intended, that the calculated dose is safe for the patient (e.g. for oral morphine or oxycodone in adult patients, not normally more than 50% higher than the previous dose). Ensure they are familiar with the following characteristics of that medicine and formulation: usual starting dose, frequency of administration, standard dosing increments, symptoms of overdose, common side effects. Link to NPSA Rapid Response Report Codeine: restricted use as analgesic in children and adolescents after European safety review – June 2013 Codeine should only be used to relieve acute moderate pain in children older than 12 years and only if it cannot be relieved by other painkillers such as paracetamol or ibuprofen alone Codeine is now contraindicated in: all children age 0–18 years who undergo tonsillectomy or adenoidectomy (or both) for obstructive sleep apnoea all patients of any age known to be CYP2D6 ultra-rapid metabolisers Codeine is not recommended for use in children whose breathing might be compromised, including those with: neuromuscular disorders; severe cardiac or respiratory conditions; upper respiratory or lung infections; multiple trauma; or extensive surgical procedures. Morphine toxicity may be increased in these settings In children age 12–18 years, the maximum daily dose should not exceed 240 mg. This may be taken in divided doses up to four times a day at intervals of no less than 6 hours. It should be used at the lowest effective dose for the shortest period. Duration of treatment should be limited to 3 days and if no effective pain relief is achieved, treatment should be reviewed by a physician Information should be given to parents and caregivers on how to recognise the signs and symptoms of morphine toxicity, and advice should be given to stop giving the child codeine and to seek medical attention immediately if the child shows these signs or symptoms, which include: reduced levels of consciousness; somnolence; respiratory depression; ‘pin-point’ pupils; lack of appetite; constipation; or nausea and vomiting Codeine should not be used by breastfeeding mothers because it can pass to the baby through breast milk and potentially cause harm See Drug Safety Update, June 2013 City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 83 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

There is the possibility of serotonin syndrome when serotonergic drugs are administered concomitantly with fentanyl-containing patches Caution is advised when fentanyl patches are co-administered with drugs that affect serotonergic neurotransmitter systems. The development of a potentially life-threatening serotonin syndrome may occur with the concomitant use of Serotonergic drugs such as Selective Serotonin Re-uptake Inhibitors (SSRIs) Serotonin Norepinephrine Re-uptake Inhibitors (SNRIs) Drugs which impair the metabolism of serotonin (including Monoamine Oxidase Inhibitors [MAOIs]) This may occur within the recommended dose. Serotonin syndrome may include one or more of the following: mental-status changes (e.g., agitation, hallucinations, coma) autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia) neuromuscular abnormalities (e.g., hyperreflexia, incoordination, rigidity) gastrointestinal symptoms (e.g., nausea, vomiting, diarrhoea) If serotonin syndrome is suspected, patches should be discontinued.

For new patients – seek SPECIALIST ADVICE. Most antiepileptics, when used in the usual dosage, are given twice daily. Lamotrigine, phenobarbital, and phenytoin, which have long half-lives, can be given once daily at bedtime. However, if large doses are administered, some antiepileptics may need to be given more frequently to avoid adverse effects associated with high peak plasma-drug concentration. Safety warnings CSM advice has been issued for the following antiepileptics Adult - see individual BNF monographs for details): Phenytoin - Blood and skin disorders Carbamazepine - Blood, liver and skin disorders Oxcarbazepine - Blood, liver and skin disorders Topiramate - Acute myopia with secondary angle closure glaucoma Sodium valproate - Blood disorders, liver toxicity and pancreatitis Lamotrigine - Serious skin disorders, bone marrow depression Available data suggests phenytoin, carbamazepine, primidone and sodium valproate are associated with decreased bone mineral density, which may lead to osteopenia, osteoporosis and increased fracture in at-risk patients. At-risk patients include those immobilised for long periods and those with inadequate sun exposure or inadequate dietary calcium. Vitamin D supplements should be considered for at-risk patients. For full details, see Drug Safety Update, April 2009 Interactions Interactions between antiepileptics are complex and may increase toxicity without a corresponding increase in antiepileptic effect. Interactions are usually caused by hepatic enzyme induction or inhibition; displacement from protein binding sites is not usually a problem. These interactions are highly variable and unpredictable. For interactions of antiepileptic drugs, see BNF Appendix 1; for advice on hormonal contraception and enzyme-inducing drugs, see BNF Section 7.3.1 and BNF Section 7.3.2. Alcohol can cause enzyme induction, which further contributes to seizure control. Concomitant use of St Johns Wort and antiepileptic medication is not recommended due to significant interactions. See Drug Safety Update November 2007 City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 88 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). Generic or brand prescribing The bioavailability of a generic drug compared to a branded drug may differ 10%. For most drugs, this is not a problem. However, some antiepileptic drugs have a narrow therapeutic index (for example, phenytoin), minor changes in bioavailability could cause breakthrough seizures and increased toxicity. The cost difference between branded and generic products is often minimal there is no cost benefit in switching and patients should remain on their own brand. The MHRA and NICE advises against switching formulations of antiepileptic drugs, and patient organisations oppose generic substitution or switching between brands. The MHRA issued guidance in November 2013: o Following a review of the available evidence, the UK Commission on Human Medicines (CHM) considered the characteristics of antiepileptic drugs and advised that they could be classified into three categories, based on therapeutic index (a comparison of the amount of a therapeutic agent that causes the therapeutic effect to the amount that causes or toxicity), solubility and absorption, to help prescribers and patients decide whether it is necessary to keep using a supply of a specific manufacturer’s product. o Category 1 – Phenytoin, carbamazepine, phenobarbital, primidone For these drugs, doctors are advised to ensure that their patient is maintained on a specific manufacturer’s product. o Category 2 – Valproate, lamotrigine, perampanel, retigabine, rufinamide, clobazam, clonazepam, oxcarbazepine, eslicarbazepine, zonisamide, topiramate For these drugs the need for continued supply of a particular manufacturer’s product should be based on clinical judgement and consultation with patient and/or carer taking into account factors such as seizure frequency and treatment history. o Category 3 - Levetiracetam, lacosamide, tiagabine, gabapentin, pregabalin, ethosuximide, vigabatrin For these drugs it is usually unnecessary to ensure that patients are maintained on a specific manufacturer’s product unless there are specific concerns such as patient anxiety, and risk of confusion or dosing errors. See Drug Safety Update, November 2013 The brand name or manufacturer's name should be quoted on prescriptions and in correspondence. Therapeutic drug monitoring Routine plasma drug level monitoring is generally unnecessary as plasma concentrations do not correlate well with therapeutic effect (this is especially true for sodium valproate). Therefore, it is important to treat the patient and not the plasma levels. Therapeutic drug monitoring may be useful in the following situations: City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 89 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). o When drug therapy is initiated and after dosage adjustments (especially with phenytoin or phenobarbital dosage adjustments); o check on compliance; o changes in drug formulation and generic substitution; o seizures in a previously well controlled patient; o suspected toxicity or adverse effects; o suspected drug interactions; o hepatic or renal disease; o pregnancy For advice on therapeutic drug monitoring, see guidance Midazolam Buccolam® is a licensed formulation of midazolam suitable for buccal administration in a range of pre-filled syringes and doses. Buccolam® is half the strength of some other unlicensed preparations.

The preservatives insulins are more effective at around room temperature than in cooler environments. In addition, it is more difficult to re-suspend a cold insulin suspension than one kept at room temperature. In-use pens (opened, i.e., after a pen needle has been attached) should be stored at room temperature (below 30°C) and should not be refrigerated. This is because of the increased risk of microbial contamination, potential for air bubbles occurring - air may enter the cartridge through the needle as the liquid contracts at the lower temperature. There is a tendency for leakage out through the needle as the liquid expands at higher temperatures (if been stored in a refrigerator). Ideally, the needle should be removed. Cartridges are not designed for multi-use and cannot be considered the same as vials. However, a single dose (In an emergency) can be withdrawn using an insulin syringe and needle.

Department of Health. Accessed: 21/8/13 https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/14782 4/Green-Book-Chapter-6-v2_0.pdf Live vaccines, in some situations, can cause severe or fatal infections in immunosuppressed individuals due to extensive replication of the vaccine strain. For this reason, severely immunosuppressed individuals should not be given live vaccines, and vaccination in immunosuppressed individuals should only be conducted in consultation with an appropriate specialist. This includes patients receiving systemic high-dose steroids, until at least three months after treatment has stopped. This would include children who receive prednisolone, orally or rectally, at a daily dose (or its equivalent) of 2mg/kg/day for at least one week, or 1mg/kg/day for one month. For adults, an equivalent dose is harder to define but immunosuppression should be considered in those who receive at least 40mg of prednisolone per day for more than one week. Occasionally, individuals on lower doses of steroids may be immunosuppressed and at increased risk from infections. In those cases, live vaccines should be considered with caution, in discussion with a relevant specialist physician Inactivated vaccines cannot replicate and so may be administered to immunosuppressed individuals, although they may elicit a lower response than in immunocompetent individuals.

Adequate oral hygiene should be maintained before and after treatment. Remedial dental work should be carried out before starting treatment in patients with concomitant risk factors. See the BNF and Drug Safety Update, November 2009 Atypical femoral fractures have been reported rarely with bisphosphonate treatment, mainly in patients receiving long-term treatment for osteoporosis. The need to continue bisphosphonate treatment for osteoporosis should be reevaluated periodically based on an assessment of the benefits and risks of treatment for individual patients, particularly after 5 or more years of use. Patients should be advised to report any thigh, hip, or groin pain during treatment with a bisphosphonate. Discontinuation of bisphosphonate treatment in patients suspected to have an atypical femoral fracture should be considered after an assessment of the benefits and risks of continued treatment.

If a dopamine-receptor agonist is required, cabergoline is preferred. Quinagolide is not licensed for the suppression of lactation. CSM advice: the ergot derived dopamine receptor agonists bromocriptine, cabergoline, lisuride and pergolide have been associated with pulmonary, retroperitoneal and pericardial fibrotic reactions. The CSM has advised that before starting treatment with these ergot derivatives, investigations such as measurement of ESR, U&Es and a chest X-ray may be appropriate. If longterm treatment is expected than lung function tests may be useful. Patients should be monitored for progressive fibrotic disorders. Dopamine agonists have been associated with excessive daytime sleepiness and sudden onset of sleep. Patients starting treatment with these drugs should be warned of the possibility of these effects and the need for caution if driving or operating machinery. Hypotensive reactions can occur during the first few days of treatment with bromocriptine, cabergoline, or quinagolide - monitor blood pressure for a few days after starting treatment and following dosage increases.

OBSTETRICS, GYNAECOLOGY, AND URINARY-TRACT DISORDERS Local guidance Trust guidelines for prophylaxis of obstetrics, gynaecology, and urinary-tract infections: link to guidelines Trust guidelines for treatment of obstetrics, gynaecology, and urinary-tract infections: link to guidelines Drugs for urinary frequency, enuresis, and incontinence First Line - Immediate release oxybutinin is first line treatment unless contraindicated Adult - see below). The use of oxybutynin may be limited by side effects. These may be reduced by commencing with a low dose and increasing gradually - usual starting dose is 2.5 mg three times a day increased weekly as tolerated to a maximum of 5 mg four times a day. Contraindications to first line immediate release oxybutinin - If a patient is unlikely to comply with three times a day dosing or is already on multiple medications it may be reasonable to try a modified release preparation before trying third-line therapy. In an elderly patient or someone at high risk of cognitive impairment, consider a second-line drug such as trospium. Second Line - A modified-release preparation of oxybutynin is effective and has fewer side-effects and therefore may be better tolerated (usually 10 mg for patients who move from 2.5 mg three times a day increased to a maximum of 20 mg daily in 5 mg steps per week) An alternative antimuscarinic, such as trospium Third Line -Third-line agents may still have good effect in patients who have failed to respond to other preparations and include solifenacin, and propiverine. Solifenacin is substantially more expensive but may be an option for those who do not tolerate oxybutynin. NICE recommends propiverine for overactive bladder but not for urinary incontinence. Mirabegron should be considered as third lline (at least 2 “standard” treatments to be tried - unless side effects are intolerable) as an alternative to more costly options such as botulinum and sacral neuromodulation. Antimuscarinic therapy should be reviewed after 6 months and if symptoms are well-controlled therapy may be reduced or discontinued, as symptoms may not recur.

The only staff who are able to prescribe cytotoxic chemotherapy are oncology consultants (or other career grade staff who are competent) and SpRs - for oncology patients and haematology consultants and SpRs for haematology patients. Physicians and their teams who admit unselected medical emergencies are not expected to either initiate or continue the prescription of chemotherapy. The responsibility for the prescription lies with the consultant in charge of that patient or whoever is providing cover for that service. It would of course be appropriate to notify the relevant team of that patient’s admission.

The dose of parenteral iron must be calculated on an individual basis. To calculate the appropriate dose, the following needs to be determined: the target Hb concentration, the actual Hb concentration and the patient's weight. New recommendations to manage risk of allergic reactions with intravenous iron-containing medicines A European wide review of intravenous iron products has issued recommendations to manage and minimise the risk of hypersensitivity reactions Any IV iron product should not be used in patients with known hypersensitivity to the product itself, or any of its excipients. The risk is higher in patients with known allergies or have immune or inflammatory conditions (eg, systemic lupus erythematosus, rheumatoid arthritis); or those with a history of severe asthma, eczema, or other atopic allergy. IV iron should not be used during pregnancy unless clearly necessary. Treatment should be confined to the 2nd or 3rd trimesters, if the benefit is clearly judged to outweigh the potential risks for both mother and foetus; Parenteral iron should only be administered by appropriately trained staff. Caution is needed with every dose of IV iron that is given, even if previous administrations have been well tolerated. A test dose is no longer recommended as it may give false reassurance because hypersensitivity reactions have been reported in patients that had a negative initial test dose. Patients should be closely monitored for signs of hypersensitivity during and for at least 30 minutes after every administration of an IV iron product In the event of a hypersensitivity reaction, treatment should be stopped immediately and appropriate management initiated.

MHRA/CHM advice Erythropoietins - tumour progression and survival in patients with cancer (December 2007 and July 2008) Clinical trial data show an unexplained excess mortality and increased risk of tumour progression in patients with anaemia associated with cancer that has been treated with erythropoietins. Many of these trials used erythropoietins outside of the licensed indications (i.e. overcorrected haemoglobin concentration or given to patients who have not received chemotherapy): erythropoietins licensed for the treatment of symptomatic anaemia associated with cancer, are licensed only for patients who are receiving chemotherapy; the decision to use erythropoietins should be based on an assessment of the benefits and risks for individual patients; blood transfusion may be the preferred treatment for anaemia associated with cancer chemotherapy, particularly in those with a good cancer prognosis. See Drug Safety Update, August 2008 CSM advice (pure red cell aplasia) There have been very rare reports of pure red cell aplasia in patients treated with erythropoietins. In patients who develop a lack of efficacy with erythropoietin therapy and with a diagnosis of pure red cell aplasia, treatment with erythropoietins must be discontinued and testing for erythropoietin antibodies considered. Patients who develop pure red cell aplasia should not be switched to another form of erythropoietin.

When IV administration is not possible, solutions may be infused subcutaneously. This technique is known as hypodermoclysis. Absorption of fluid subcutaneously will be quite slow and infusions will need to run more slowly then when given IV. Normally only crystalloid solutions are used (500 mL). See local policy Isotonic solutions may be infused safely into a peripheral vein. Solutions more concentrated than plasma e.g. 20% glucose, should be given through an indwelling catheter positioned in a large vein. Clinicians should be aware that intravenous hypotonic saline (0.18% saline/4% glucose solution) is now contraindicated in children except under expert medical supervision in paediatric specialist settings – such as renal, liver, cardiac, high dependency and intensive care units. Use of this solution in children outside these conditions has resulted in several cases of hyponatraemia, including some that were fatal Following advice from the National Patient Safety Agency intravenous potassium must only be administered using commercial pre-mixed solutions unless there are exceptional circumstances. See local policy. The pharmacy now stocks a wider range of pre-mixed potassium infusions.

Enteral feeding offers a number of advantages over parenteral feeding: o Sterile technique is not required and the dangers associated with the parenteral route are avoided, e.g. sepsis with central venous lines. o Enhanced utilization of nutrients o Ease and safety of administration o The maintenance of gastrointestinal structure and functional integrity is associated with small amounts of nutrients being continuously presented to the bowel o Enteral feeding is approximately one-tenth the cost of parenteral feeding Advice on enteral feeding is available from the dietitians It is important to note that some drugs may interact with nasogastric feeds. NO drugs should ever be mixed with feeds before administration. In addition, there may be an interaction following ingestion. For information, please contact your ward pharmacist or dietician, or the Medicines Information Centre.

Cyclo-oxygenase-2 selective inhibitors, diclofenac (150 mg daily) and ibuprofen (2.4 g daily) are associated with an increased risk of thrombotic events. Available data indicate that the cardiovascular risk with diclofenac is similar to that of the selective COX-2 inhibitors. Consequently, diclofenac is now contraindicated in those with: ischaemic heart disease; peripheral arterial disease; cerebrovascular disease; and established congestive heart failure (New York Heart Association [NYHA] classification II–IV). Diclofenac treatment should only be initiated after careful consideration for patients with significant risk factors for cardiovascular events (e.g., hypertension, hyperlipidaemia, diabetes mellitus, and smoking). Naproxen (1 g daily) is associated with a lower thrombotic risk, and low doses of ibuprofen (1.2 g daily or less) have not been associated with an increased risk of myocardial infarction. NSAIDs and gastro-intestinal events All NSAIDs are associated with serious gastro-intestinal toxicity; the risk is higher in the elderly. Evidence on the relative safety of non-selective NSAIDs indicates differences in the risks of serious upper gastro-intestinal side-effects—piroxicam (see also CHMP advice), ketoprofen, and ketorolac are associated with the highest risk; indometacin, diclofenac, and naproxen are associated with intermediate risk, and ibuprofen with the lowest risk (although high doses of ibuprofen have been associated with intermediate risk). Selective inhibitors of cyclo-oxygenase-2 are associated with a lower risk of serious upper gastro-intestinal side-effects than non-selective NSAIDs. Recommendations are that NSAIDs associated with a low risk e.g. ibuprofen are generally preferred, to start at the lowest recommended dose and not to use more than one oral NSAID at a time. See also Cautions and Contra-indications. The combination of a NSAID and low-dose aspirin can increase the risk of gastrointestinal side-effects; this combination should be used only if absolutely necessary and the patient should be monitored closely. City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 172 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). Asthma - CSM warning: Any degree of worsening of asthma may be related to the ingestion of NSAIDs, either prescribed or (in the case of ibuprofen and others) purchased over the counter Renal Impairment - MHRA warning: Patients at risk of renal impairment or renal failure (particularly elderly people) should avoid NSAIDs if possible. If NSAID treatment is necessary, then the lowest effective dose for the shortest possible duration should be used to control symptoms. The renal function of such patients should be carefully monitored during NSAID treatment. It is important to consider other concomitant disease states, conditions, or medicines that may precipitate reduced renal function when prescribing NSAIDs. GENERAL ADVICE ON PRESCRIBING NSAIDS AND COXIBS The lowest effective dose of NSAID or coxib should be prescribed for the shortest time necessary for control of symptoms. The need for long-term treatment should be reviewed periodically. Not to use more than one oral NSAID at a time and ALL NSAIDs are contraindicated in patients with peptic ulceration. Prescribing should be based on the safety profiles of individual preparations and on an assessment of a patient’s individual risk factors, including any history of cardiovascular and gastrointestinal illness Prescribers should not switch between NSAIDs without careful consideration of the overall safety profile of the products, a patient’s individual risk factors, and patient preference. Concomitant aspirin (and possibly other antiplatelet drugs) greatly increase the gastrointestinal risks of NSAIDs and severely reduce any gastrointestinal safety advantages of coxibs. Aspirin should only be coprescribed if necessary.

Careful monitoring is required Methotrexate Important Note that the above dose is a weekly dose. To avoid error with low-dose methotrexate, it is recommended that: the patient is carefully advised of the dose and frequency and the reason for taking methotrexate and any other prescribed medicine (e.g. folic acid); only one strength of methotrexate tablet (usually 2.5 mg) is prescribed and dispensed; the prescription and the dispensing label clearly show the dose and frequency of methotrexate administration; the patient is warned to report immediately the onset of any feature of blood disorders (e.g. sore throat, bruising, and mouth ulcers), liver toxicity (e.g. nausea, vomiting, abdominal discomfort, and dark urine), and respiratory effects (e.g. shortness of breath). See also the National Patient Safety Agency guidance and the BNF. CSM advice In view of reports of blood dyscrasias (including fatalities) and liver cirrhosis with lowdose methotrexate, the CSM has advised: full blood count and renal and liver function tests before starting treatment and repeated weekly until therapy stabilised, thereafter patients should be monitored every 2–3 months that patients should be advised to report all symptoms and signs suggestive of infection, especially sore throat Methotrexate Tablets: 2.5 mg Injection: contact pharmacy for advice Gold Sodium aurothiomalate Injection: 10 mg/0.5 mL, 20 mg/0.5 mL, 50 mg/0.5 mL City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 176 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

Antimalarials To avoid excessive doses in obese people, doses of hydroxychloroquine should be calculated on the basis of ideal body weight - calculators A review group convened by the Royal College of Ophthalmologists has updated guidelines for screening to prevent ocular toxicity on long term treatment with chloroquine, hydroxychloroquine, and mepacrine See: Royal College of Ophthalmologists guidance – October 2009. Chloroquine Tablets: 150 mg Hydroxychloroquine sulphate Tablets: 200 mg Drugs affecting the immune response Thiopurine drugs (azathioprine, 6-mercaptopurine and thioguanine) are converted in vivo to provide the therapeutic effect. TPMT provides the major catabolic pathway for these drugs. If the enzyme is absent then there is a risk of toxicity resulting in severe bone marrow depression. Complete deficiency of TPMT occurs in 1:300 Caucasians (it is also known in patients of African origin). Partial deficiency occurs in more than 1:10. Ciclosporin should be prescribed and dispensed by brand name. Ciclosporin is a critical-dose drug with a narrow therapeutic index. Patients should be stabilised on a single brand of ciclosporin because switching between formulations without close monitoring may lead to clinically important changes in bioavailability. All products that contain ciclosporin are interchangeable only if careful therapeutic monitoring takes place. Leflunomide has an active metabolite with a very long half life which needs to be actively removed (using colestyramine or activated charcoal) if there are serious adverse effects, before starting other DMARDs or before conception. Hepatotoxicity can occur with leflunomide (potentially life threatening) in the first 6 months of treatment. Monitor LFTs before treatment and every 2 weeks for the first 6 months then every 8 weeks.

Although patient response may vary, overall efficacy is modest; the frequency of nocturnal leg cramps is reduced by about 20-25% in ambulatory patients - around one episode a week difference. The MHRA advises that quinine is not a routine treatment for nocturnal leg cramps and should only be used if cramps cause regular disruption of sleep. Consider quinine only when cramps are very painful or frequent; when other treatable causes of cramp have been ruled out, and when nonpharmacological measures have not worked, (e.g. passive stretching exercises). After an initial trial of 4 weeks, treatment should be stopped if there is no benefit.

Specific drugs can be searched by using the Find function (Ctrl+F). Initially patients should be monitored closely for adverse effects as well as benefit. Treatment should be interrupted at 3-monthly intervals to assess the need for further quinine. In patients taking quinine long-term, a trial discontinuation may be considered. Adverse events may include tinnitus, impaired hearing, headache, nausea, disturbed vision, confusion, flushing, and abdominal pain. A rarer but more serious adverse reaction is thrombocytopenia, thought to be a hypersensitivity reaction. Patients should be instructed to stop treatment and consult a physician if signs of thrombocytopenia occur, such as unexplained petechiae, bruising or bleeding. Quinine has a number of potentially significant drug interactions, including with digoxin and warfarin. It also has significant toxicity in overdose, which can result in death or permanent visual loss.

Specific drugs can be searched by using the Find function (Ctrl+F). 11.1 ADMINISTRATION OF DRUGS TO THE EYE Adult - see BNF for further information Children – see BNFC for further information Drugs are most commonly administered to the eye by topical application as eye drops or eye ointments. Eye drops are usually preferable for daytime use, as they are convenient to apply and do not blur vision. The conjunctival sac can normally accommodate volumes of between 7 and 30L. Volumes in excess of this can be systematically absorbed which may give rise to adverse effects. It is therefore important to instil only one drop at a time. If two or more sets of eye drops are to be administered at the same time, dilution and overflow can occur. A few minutes should be left between applications to minimise this effect. Drops, which sting, should normally be used last as these cause reflex tear secretion that may reduce the effectiveness of subsequent instillations. Eye ointments remain in contact with the conjunctiva or eyelid for long periods resulting in good levels of drug within the eye. They are, therefore, useful for night-time therapy. The ointment base also helps to soften crusts in infectious conditions such as blepharitis and bland ointments can be used to lubricate and protect the eye. Because of the film that they form, ointments can blur vision and may be unsuitable for daytime use. Eye ointments are applied by placing approximately 0.5-1cm ribbon of the ointment to the inside of the lower lid. Patients should be warned not to drive or perform other skilled tasks until vision is clear after using eye drops or eye ointments. Contact lenses should not generally be worn while using eye drops containing preservatives, or eye ointments. For further information see the BNF Adult or Children. Preservatives Various preservatives are used in multidose eye drops. These may be a source of hypersensitivity reactions. Frequent use of preserved drops can cause toxic keratopathy. Minims® are available for many preparations (preservative free bottles are available also from Moorfields Eye Hospital and other special manufacturers). They are obviously more expensive, but are very useful in those patients in whom you suspect sensitivities or allergies to preservatives, for use during or after surgery, or for patients who wear soft contact lenses. Preservative free drops are recommended for intensive application (e.g. hourly). Order of instillation City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 184 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF. Specific drugs can be searched by using the Find function (Ctrl+F). In the case of multiple therapy, it is recommended to leave a minimum of 3 minutes between instilling drops .The order in which different drops are instilled is not particularly important. Drops that sting should normally be used last as these cause reflex tear secretion, which may reduce the effectiveness of subsequent eye drops. Where ointments and drops are used together, ointments are put in after drops.

Specific drugs can be searched by using the Find function (Ctrl+F). 11.2 CONTROL OF MICROBIAL CONTAMINATION Adult - see BNF for further information Children – see BNFC for further information Eye drops in multi-use containers should be discarded 4 weeks after opening to avoid contamination. Note: preservative-free preparations may be single-use only or to be discarded 1 week after opening. It is not generally necessary to use separate bottles for each eye (except immediately after eye surgery), but care should be taken to avoid touching the eye(s) during use to avoid contamination. Most drops do not need to be kept in a fridge, unless directed otherwise.

The risk is greater when these preparations are applied to large areas of the body, and clothing or dressings become soaked with the ointment. Patients should be told to keep away from fire or flames, and not to smoke when using these preparations. The risk of fire should be considered when using large quantities of any paraffin-based emollient. General These include moisturising ointments and creams, bath oils and soap substitutes. Emollients soothe and hydrate the skin and are indicated for all dry or scaling disorders. They require frequent application because their effects are shortlived, but when used correctly can be extremely effective in reducing inflammation and improving skin texture. . Aqueous cream is suitable for most patients with dry skin, but more greasy preparations (white soft paraffin, emulsifying ointment and a white soft paraffin/liquid paraffin combination) are available. Some patients may be sensitive to the preserving agent in aqueous cream and may need to be offered an alternative The severity of the condition can be used as a guide as to which preparation is most appropriate. Preparations containing an antibacterial should be avoided unless infection is present or is a frequent complication. A wide range of products is available as patients can become sensitised to or intolerant to the product. Eczema and Psoriasis Emollients add a protective lipid layer to the skin, reducing dryness and itching and provide a steroid sparing effect. They may have an antipsoriatic effect and prevent fissuring and pruritus but they have no direct anti-inflammatory effect. Bath additives have a marginal effect and some may even make eczema worse City Hospitals Sunderland Prescribing Guide v2014.1 (Jan 2014) 206 Medicines in the formulary are listed in chapters and subsections that generally correspond with those in the BNF.

The side effects of topical steroids are dependent on the product strength and duration of use; there are four classifications of potency: o o o o Mild Moderately Potent Potent Very Potent Preparations in the mild and moderately potent groups are rarely associated with side-effects. This is not the case with potent and very potent preparations, which can give rise to systemic as well as local effects. The risk of systemic side-effects is dependent on the potency of preparation used, duration of treatment and the area treated. Absorption is greatest from thin, inflamed or raw skin, and is increased by occlusion of the treatment area The potency of the steroid used should be appropriate to the severity and site of the condition. Try to use the minimum amount of the least potent steroid at the lowest effective concentration for the minimum period of time. Patients should be initiated on the highest potency topical corticosteroid that is clinically required and then stepped down. The patient may be stepped down to a lower potency steroid or the frequency of use of a higher potent steroid can be reduced, for example: Once / Twice Daily → Alternate Days or less frequently, as necessary. Only mild steroids should be used on the face. Infants and the elderly tend to have thinner skin and thus weaker preparations should be used. Patients and nurses should be advised to use gloves if applying large quantities of steroid preparations. Advise patient/carer to wash their hands after applying steroid preparations to avoid atrophy of skin on fingertips. Adequate use of emollients may reduce the amount of steroid preparation required in dry scaly conditions. Eczema and Psoriasis Many forms of eczema tend to be chronic and are best managed on mild and moderately potent steroids; potent and very potent preparations should only be used for short periods to control acute episodes. In psoriasis, potent steroids are generally required for treatment of single plagues on limbs and trunk, whereas flexures and the face should only be treated with mild potency steroids.

Specific drugs can be searched by using the Find function (Ctrl+F). Choice of Preparation Ointments are preferable to creams as they have a deeper, more prolonged emollient effect and increase the penetration of steroid. They are also less likely to cause irritation and/or sensitisation to the product, as they do not contain preservatives. Patients may prefer creams for application to the face and they can be more suitable for moist or weeping lesions. Frequency of application NICE guidance recommends that topical corticosteroids for atopic eczema should be prescribed for application only once or twice daily. Once a day may be as effective as twice daily application. Topical corticosteroids should be spread thinly on the skin but in sufficient quantity to cover the affected areas. The length of cream or ointment expelled from a tube may be used to specify the quantity to be applied to a given area of skin. This length can be measured in terms of a fingertip unit (the distance from the tip of the adult index finger to the first crease). One fingertip unit (approximately 500 mg) is sufficient to cover an area that is twice that of the flat adult palm. Suitable quantities of preparations to be prescribed for specific areas of the body. These amounts are usually suitable for an adult for twice a day application for two weeks.

IMMUNOLOGICAL PRODUCTS AND VACCINES 14.1 ACTIVE IMMUNITY Adult - see BNF for further information Children – see BNFC for further information CHILDHOOD IMMUNISATION PROGRAMME The immunisation programme takes place over the course of five years with the aim to protect all children against various preventable childhood infections. Immunisations are often given more than once to make sure the protection continues. This is known as a booster immunisation. Children usually need booster immunisations when they have reached pre-school age (five years old), and again before they leave school (between 13 and 18 years of age). Immunisation schedule The Immunisation schedule can be downloaded from Public Health England: Immuminsation schedule, June 2013 OR from the BNF Adult or Children. If any course of immunisation is interrupted, it should be resumed and completed as soon as possible. There is no need to start any course of immunisation again. An algorithm for vaccinating individuals with uncertain or incomplete immunisation status is available from Public Health England: Vaccination of Individuals with Incomplete or Uncertain Immunisation Status ADULT IMMUNISATION PROGRAMME Five doses of diphtheria, tetanus and polio vaccines ensure long-term protection through adulthood. Individuals who have not completed the five doses should have their remaining doses at the appropriate interval. Where there is an unclear history of vaccination, adults should be assumed to be unimmunised. A full course of diphtheria, tetanus and polio should be offered. Older adults (65 years or older) should be routinely offered a single dose of pneumococcal polysaccharide vaccine, if they have not previously received it. Annual influenza vaccination should also be offered. Selective vaccines should also be considered for young adults unprotected against diseases including measles, mumps, rubella and meningococcal C. Other vaccinations should be considered for any adult with underlying medical conditions and those at higher risk because of their lifestyle. These vaccinations include Hib, MenC, influenza, pneumococcal and hepatitis B.
