Admit immediately anyone who has: - Stridor or respiratory difficulty: o Respiratory distress, drooling, systemically very unwell, painful swallowing, muffled voice: suspect acute epiglottis. Do not examine the throat of anyone who has suspected epiglottitis. o Upper airway obstruction. - Dehydration or reluctance to take any fluids. - Severe suppurative complications (e.g. peri-tonsillar abscess or cellulitis, parapharyngeal abscess, retropharyngeal abscess, or Lemierre syndrome) as there is a risk of airway compromise or rupture of the abscess. - Signs of being markedly systemically unwell and is at risk of immunosuppression. - Suspected Kawasaki disease. - Diphtheria: characteristic tonsillar or pharyngeal membrane. - Signs of being profoundly unwell and the cause is unknown or a rare cause is suspected, for example: o Stevens–Johnson syndrome: high fever, arthralgia, myalgia, extensive bullae in the mouth followed by erosion and a greyish white membrane. o Yersinial pharyngitis: fever, prominent cervical lymphadenopathy, abdominal pain with or without diarrhoea. - If the person is on chemotherapy, has known or suspected leukaemia, asplenia, aplastic anaemia or HIV/AIDS, or is taking an immunosuppressive drug following a transplant: Seek immediate specialist advice or referral. Meanwhile check the FBC urgently. Refer or seek urgent specialist advice for anyone who has severe oral mucositis. Who should I refer for consideration of tonsillectomy? Identify people who may need non urgent referral for consideration of tonsillectomy: - Confirm the diagnosis of recurrent tonsillitis by history and examination, if possible differentiating it from pharyngitis. In practice this may be difficult to do because people do not always consult when they have sore throat and there may be uncertainty about whether previous sore throats were due to acute tonsillitis or pharyngitis. - Note whether the frequency of episodes is increasing or decreasing. - In most children only consider referral for tonsillectomy if all of the following criteria are met: o The child has five or more episodes of acute sore throat per year, documented by the parent or clinician. o Symptoms have been occurring for at least a year. o The episodes of sore throat have been severe enough to disrupt the child's normal behaviour or day to day functioning. - Refer if the child has guttate psoriasis which is exacerbated by recurrent tonsillitis. - Refer if the child has a history of sleep apnoea, daytime drowsiness, and failure to thrive. - Refer adults if they have had had five or more episodes per year of sore throat due to tonsillitis. The episodes should have been disabling and have prevented normal functioning. When should I refer or seek advice? - If the person may be immunosuppressed: - If taking a disease-modifying anti-rheumatic drug (DMARD) and immediate admission is not appropriate then: o Take blood for a full blood count (FBC). Arrange to contact them later with the result. o Withhold the DMARD whilst awaiting the result and until discussed with the hospital rheumatology service (or follow local protocols). o Seek urgent specialist advice/referral if the person has a low white cell count or deteriorates. o Provide symptomatic relief. o Consider prescribing an antibiotic taking into account potential interactions with DMARDs. - If the person is taking carbimazole (which can cause idiosyncratic neutropenia) take an urgent FBC and withhold the drug until the result is available. Seek specialist advice. Consider prescribing an antibiotic. When should I investigate? - Throat swabs or rapid antigen tests should not be carried out routinely in the investigation of acute sore throat. - If the person is at risk of immunosuppression see Referral. - If infectious mononucleosis (glandular fever) is suspected and the person wishes to be tested: In immunocompetent people over 12 years of age, the following tests may be done: o Full blood count, differential white cell count and blood film. o Heterophile antibodies (Monospot): false negative results are less likely after the second week of the illness. 2 o Liver function tests. In children under 12 years of age, and in people who are immunocompromised at any age, viral serology for the EpsteinBarr virus is preferred. o Prevent the development of rheumatic fever and acute glomerulonephritis. For people with sore throat where it is felt safe not to prescribe antibiotics immediately: What advice should I give? - Reassure the individual that a sore throat is generally self limiting, with most immunocompetent people recovering after 7 days with or without antibiotic treatment. - Advise the person to see a healthcare professional if they do not improve. Explain that they should seek urgent medical attention if they develop any difficulty breathing, stridor, drooling, a muffled voice, severe pain, dysphagia, or if they are not able to swallow adequate fluids or become systemically very unwell. - Advise regular use of paracetamol or ibuprofen to relieve pain and fever. - Provide advice regarding food and drink to avoid exacerbating pain (e.g. avoid hot drinks). - Suggest the use of simple mouthwashes (e.g. warm salty water) at frequent intervals until the discomfort and swelling subside. - Discuss the role of antibiotics (see Prescribing an antibiotic). - If the person is immunosuppressed: o If they are taking a disease-modifying anti-rheumatic drug (DMARD), or carbimazole tell them to stop this while waiting for result of a full blood count (FBC). Arrange to contact them later with the result and explain that you will seek specialist advice. o Stress that they should seek immediate medical advice if they become systemically unwell. o Explain to all other people who are immunosuppressed that you will seek urgent specialist advice. This includes people who: - Have leukaemia, aplastic anaemia, asplenia or HIV/AIDS. - Are on chemotherapy or who are taking an immunosuppressive drug following a transplant. Advise them not to stop their medication unless after your discussion with the specialist they are advised to do so. o o Use of delayed antibiotic prescriptions may be considered. Delayed prescription may help to reduce re-attendance. However, there is no evidence to indicate that it is different to 'no antibiotics' in terms of symptom control, patient satisfaction and disease complications. Prescribe an antibiotic for: o o o o o o o Those with features of marked systemic upset. Those at increased risk of complications. Have a low threshold for prescribing an antibiotic in people: With an increased risk of severe infection (e.g. diabetes or immunocompromised). Who are at risk of immunosuppression (e.g. on disease-modifying antirheumatic drugs [DMARDs], carbimazole). With a history of valvular heart disease. With a history of rheumatic fever. People with peritonsillar abscess or peritonsillar cellulitis will receive antibiotics in secondary care: admit immediately. An antibiotic may be useful in: o o Preventing cross-infections with group A beta-haemolytic streptococcus (GABHS) in closed institutions such as barracks or boarding schools. However, it should not be used routinely to prevent cross infection in the general community. Treating recurrent sore throat associated with GABHS. Which antibiotic should I prescribe for sore throat? Prescribe phenoxymethylpenicillin (or erythromycin if the person is allergic to penicillin) for 10 days. Avoid prescribing broad-spectrum penicillins (such as amoxicillin and ampicillin) for the blind treatment of sore throat.l summary: Management of persistent sore throat When should I prescribe an antibiotic for sore throat? Do not routinely prescribe antibiotics for acute sore throat. Antibiotics should not be prescribed to: o Secure symptomatic relief. o Prevent suppurative complications. o Treat recurrent non-streptococcal sore throat. 3 How should I manage someone with persistent sore throat? Reconsider the initial diagnosis. Consider alternative diagnosis or further investigation if the individual has not responded to a course of antibiotics. Consider cancer if the sore throat is persistent, especially if there is a neck mass (cervical node metastases). Refer urgently anyone with: An unexplained persistent sore or painful throat. Persistent would refer to a time frame of 3 to 4 weeks. Red, or red and white patches, or ulceration or swelling of the oral/pharyngeal mucosa for more than 3 weeks. Pain on swallowing or dysphagia for more than 3 weeks. Suspect infectious mononucleosis if sore throat and lethargy persist into the second week, especially if the person is 15– 25 years of age. Request a full blood count, differential white cell count and blood film to look for mononuclear leucocytosis, and a Monospot test to look for heterophile antibodies if the person wishes to be tested. Consider non-infectious causes of sore throat (for example, gastro-oesophageal reflux disease, chronic irritation from cigarette smoke, alcohol, or hayfever).

Supply 200 ml. 4 ACUTE OTITIS MEDIA (AOM) Scenario: First-line treatment Erythromycin (use high doses) or clarithromycin (use standard doses) are alternative antibiotics if the child has a documented allergy to penicillin. Practical prescribing points If a delayed prescription is issued, advise the parent to destroy the script or dispose of the antibiotics if they are not used for the current episode of acute otitis media. Broad-spectrum antibiotics may cause gastrointestinal adverse effects such as vomiting. A skin rash may also occur. Ibuprofen may occasionally cause gastrointestinal adverse effects, such as discomfort, nausea, and diarrhoea. Which therapy? This guidance is primarily intended for the treatment of children with acute otitis media (AOM). Although AOM can occur in adults, it is less common, and there is little evidence on which to base guidelines. In the absence of good evidence or guidelines on the treatment of AOM in adults, treatment should be the same as in children. Offer analgesia if pain is present. For most children, this is the mainstay of treatment. Paracetamol is the preferred treatment. Ibuprofen is an alternative to paracetamol. Refer? Admission or immediate referral to an Ear, Nose, and Throat (ENT) specialist is indicated in children with: Antibiotics should not be routinely prescribed for uncomplicated AOM. Discuss and reassure the individual or their parent on the benefits of and drawbacks of using antibiotics for AOM. The Shared decision making sections are useful resources for this. Sudden severe hearing loss (except in simple perforation) Sudden dizziness with nystagmus Signs suggesting meningitis Progression to mastoiditis Elective referral to an ENT department is indicated in: Children with persistent problems with effusion, discharge, or perforation (if not healed after 6 weeks) Children with frequent episodes of AOM and proven hearing loss (four episodes or more in a period of 6 months) Children in whom there is persisting effusion or impaired hearing after 3 to 6 months (see the CKS topic on Otitis media with effusion) Note: have a low threshold for referral of children with serious craniofacial abnormalities or immune deficiencies that are not responding to primary care management, as they are at high risk of developing head and neck complications. However, some children may significantly benefit from antibiotics. Consider prescribing antibiotics in the following children: All children aged 6 months and under Children aged between 6 months and 2 years where the diagnosis is reasonably certain Children older than 2 years where there are severe symptoms: o Moderate or severe ear pain (otalgia) with a fever of 39°C or above, or systemic features such as vomiting o Severe local signs, such as perforation with purulent discharge o Bilateral AOM A good compromise is to use a 'wait and see' policy by issuing a delayed prescription to be redeemed. This is a compromise where parents are issued with a prescription to be redeemed within 72 hours only if the condition has not adequately improved. Investigate? No investigations are indicated for a first episode of acute otitis media in primary care. Choice of antibiotic: Amoxicillin is the usual first-line antibiotic. Treat for 5 days. If there are severe symptoms present, or there has been a previous episode of AOM within the last month, use high doses (double the standard dose). Most people do not require follow-up. Ask the parent to arrange a follow-up appointment if symptoms have not significantly improved after 3 days, whether the child has been given an antibiotic or not. 5 If a delayed prescription has been used, the parent should seek advice 3 days after the antibiotic has been taken. There is no advantage in using an antibiotic to cover beta-lactamase resistant organisms (e.g. co-amoxiclav) in the initial treatment of AOM Consider active follow-up in the following circumstances: The person is a young child (under 2 years of age). There are systemic symptoms such as high temperature (> 39°C) or vomiting. There is discharge from the ear. Visualisation of the tympanic membrane can be difficult when there is discharge present. Reexamine after 2 weeks to assess the integrity of the membrane and to check for complications. If there is a perforation still present, monitor the situation and consider referral if it has not healed after 6 weeks. It demonstrates favourable pharmacokinetics, with high concentrations forming in the middle ear. Amoxicillin has a relatively narrow spectrum of microbiological activity (compared with some other broad-spectrum antibiotics), targeting most of the bacteria involved in AOM. Consequently, it has relatively few adverse effects, and a lower potential for causing antibiotic resistance. The macrolides are suitable alternatives to amoxicillin in people allergic to penicillin. They are active against most of the bacterial pathogens involved in otitis media, although resistance to them is increasing, especially in H. influenzae. Paracetamol and ibuprofen are the mainstays of treatment for most people with AOM. They are effective and relatively safe antipyretics and analgesics in both children and adults Shared decision making Erythromycin is a commonly used option, but requires frequent dosing and may cause adverse effects. Most bouts of ear infection clear on their own within a few days. Clarithromycin is generally better tolerated than erythromycin, and is a suitable alternative if erythromycin is poorly tolerated. It also has a more convenient dosing regimen Painkillers such as paracetamol or ibuprofen are the main treatment. Use regularly until the pain eases. These will also lower a raised temperature. Antibiotics are not advised in most cases. They are an option if the infection is severe, or if it does not ease after 2–3 days: Amoxicillin is the common antibiotic used for ear infections. Erythromycin or clarithromycin are alternatives for people allergic to penicillin. 1st-line: low dose amoxicillin Licensed use: yes Patient Information: Continue to take painkillers if needed. Discard any remaining medicine safely. Amoxicillin s/f suspension: 62.5mg three times a day Age from 1 month to 11 months Amoxicillin 125mg/5ml s/f susp. Take 2.5ml three times a day for 5 days. Supply 100 ml. Antibiotics may cause side-effects such as diarrhoea or feeling sick. Antibiotics Prescribe amoxicillin first-line, if an antibiotic is required. There is evidence from randomized controlled trials (RCTs) that it is more effective than placebo and as effective as other antibiotics in the treatment of acute otitis media (AOM). The following factors also favour its use]: Amoxicillin s/f suspension: 125mg three times a day Age from 1 year to 4 years 11 months Amoxicillin 125mg/5ml s/f susp.

Supply 20 tablets. 1st line pen allerg: high dose erythromcyin 7 Drugs not included Antihistamines or decongestants are not recommended for use in AOM, as they are not effective and have adverse effects Antibiotics © NHS Institute for Innovation and Improvement Broad-spectrum penicillin-derived antibiotics (other than amoxicillin) do not offer any advantages compared with amoxicillin. In general, there is less evidence from randomized controlled trials to support the use of alternative broad-spectrum antibiotics, and in addition: Ampicillin has to be taken more frequently than amoxicillin Phenoxymethylpenicillin is effective against Streptococcus pneumoniae, but lacks efficacy against Haemophilus influenzae Co-amoxiclav is not necessary in the initial treatment of AOM It is a suitable second-line treatment if initial treatment is unsuccessful Cephalosporins are not usually recommended in the first-line treatment of AOM. Although recent RCTs have confirmed the efficacy of ceftriaxone, it is taken as an intramuscular injection, which is inconvenient for use in primary care. In addition, cephalosporins are not suitable for people with allergies to penicillin, who may be cross-sensitive to cephalosporins Quinolones are contraindicated in children under 16 years of age. In addition, they should only be used in adults when the organism sensitivity to them is known, as there are growing concerns about the development of resistance to these drugs in the community. If used, a quinolone with enhanced anti-pneumococcal activity should be selected (e.g. moxifloxacin) Trimethoprim and co-trimoxazole are not recommended, owing to safety and resistance issues. Analgesia and other drugs Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs), other than ibuprofen, are excluded because of their relatively extensive adverse-effect profiles. In addition, aspirin should not be used in children under the age of 16 years 8 Refer? Admission or immediate referral to an Ear, Nose, and Throat (ENT) specialist is indicated in children with: Persistent acute otitis media/ treatment failure Which therapy? This guidance is primarily intended for the treatment of children with acute otitis media (AOM). Although AOM can occur in adults, it is less common, and there is little evidence on which to base guidelines. In the absence of good evidence or guidelines on the treatment of AOM in adults, treatment should be the same as in children. If an antibiotic has not been given previously, prescribe a first-line antibiotic. Amoxicillin is the usual first-line antibiotic. Treat for 5 days with high doses (double the standard dose). Erythromycin or clarithromycin are alternative antibiotics if the child has a documented allergy to penicillin (treat with high doses of erythromycin or standard doses of clarithromycin for 5 days). If an antibiotic has been prescribed previously and symptoms have not resolved, check compliance. If this was unsatisfactory, consider represcribing a first-line antibiotic (this may also be an option if symptoms have improved but not cleared completely). If compliance was satisfactory, prescribe a second-line antibiotic. Co-amoxiclav is the preferred antibiotic. Prescribe a high dose (double standard dose) for 5 days. If the child is allergic to penicillin and has already taken erythromycin or clarithromycin, seek specialist advice from a microbiologist. Continue analgesia if pain is present. Paracetamol is the preferred treatment. Ibuprofen is an alternative to paracetamol. Sudden severe hearing loss (except in simple perforation) Sudden dizziness with nystagmus Signs suggesting meningitis Progression to mastoiditis Elective referral to an ENT department is indicated in: Children with persistent problems with effusion, discharge, or perforation (if not healed after 6 weeks) Children with frequent episodes of acute otitis media and proven hearing loss (four episodes or more in a period of 6 months) Children in whom there is persisting effusion or impaired hearing after 3 to 6 months (see the CKS topic on Otitis media with effusion). Seek specialist advice if acute symptoms of otitis media persist despite the use of a second-line antibiotic. Note: have a low threshold for referral of children with serious craniofacial abnormalities or immune deficiencies that are not responding to primary care management, as they are at high risk of developing head and neck complications. Investigate? Consider sending a swab for culture and microbial sensitivity testing if there is perforation of the tympanic membrane that allows for a sample to be taken. This may be especially useful if first-line antibiotic treatment has failed. Practical prescribing points Broad-spectrum antibiotics may cause gastrointestinal adverse effects such as vomiting. A skin rash may also occur. Ibuprofen may occasionally cause gastrointestinal adverse effects, such as discomfort, nausea, and diarrhoea. Co-amoxiclav: the Committee on Safety of Medicines has advised that the incidence of cholestatic jaundice with co-amoxiclav is about six times greater than with amoxicillin alone. Older people (over 65 years) are at greatest risk, and cases in children are rare. The condition is usually selflimiting and very rarely fatal. Ask the parent to arrange a follow-up appointment if symptoms have not significantly improved after 3 days. Check for complications. If a first-line antibiotic has been used, consider trying a second-line antibiotic. If a second-line antibiotic has been used, seek specialist advice. Consider active follow-up in the following circumstances: 9 The person is a young child (under 2 years of age). There are systemic symptoms such as high temperature (> 39°C) or vomiting. There is discharge from the ear. Visualisation of the tympanic membrane can be difficult when there is discharge present. Reexamine after 2 weeks to assess the integrity of the membrane and to check for complications. If there is a perforation still present, monitor the situation and consider referral if it has not healed after 6 weeks.

They are effective and relatively safe antipyretics and analgesics in both children and adults Second-line antibiotics Co-amoxiclav is the preferred second-line antibiotic in children who are not allergic to penicillin. It is a combination of amoxicillin and clavulanic acid (a beta-lactamase inhibitor Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs), other than ibuprofen, are excluded because of their relatively extensive adverse-effect profiles. In addition, aspirin should not be used in children under the age of 16 years Antihistamines or decongestants are not recommended for use in AOM, as they are not effective and have adverse effects Antibiotics Prescribe amoxicillin first-line, if an antibiotic is required. There is evidence from randomized controlled trials (RCTs) that it is more effective than placebo and as effective as other antibiotics in the treatment of acute otitis media (AOM). The following factors also favour its use Amoxicillin provides coverage against most of the bacteria involved in AOM, including penicillin-intermediate Streptococcus pneumoniae (bacteria in an intermediate stage of developing full penicillin resistance) when used at adequate doses. Clarithromycin is generally better tolerated than erythromycin, and is a suitable alternative if erythromycin is poorly tolerated. It also has a more convenient dosing regimen. It is effective against beta-lactamase-producing bacteria, including Moraxella catarrhalis, Haemophilus influenzae and most strains of Streptococcus pneumoniae (although it is less effective against resistant strains). It is well absorbed and forms good concentrations in the middle ear. There is evidence from randomized controlled trials that co-amoxiclav is as effective as other beta-lactamase-resistant antibiotics (e.g. thirdgeneration cephalosporins) and azithromycin. It is taken orally, and is inexpensive. When used in short courses, it has relatively few adverse effects. Broad-spectrum penicillin-derived antibiotics (other than amoxicillin) do not offer any advantages compared with amoxicillin. In general, there is less evidence from randomized controlled trials to support the use of alternative broad-spectrum antibiotics, and in addition: There is no advantage in using an antibiotic to cover beta-lactamaseresistant organisms (e.g. co-amoxiclav) in the initial treatment of AOM It demonstrates favourable pharmacokinetics, with high concentrations forming in the middle ear. Amoxicillin has a relatively narrow spectrum of microbiological activity (compared with some other broadspectrum antibiotics), targeting most of the bacteria involved in AOM. Consequently it has relatively few adverse effects, and a lower potential for causing antibiotic resistance. The macrolides are suitable alternatives to amoxicillin in people allergic to penicillin. They are active against most of the bacterial pathogens involved in otitis media, although resistance to them is increasing, especially in H. influenzae. Erythromycin is a commonly used option, but requires frequent dosing and may cause adverse effects. 11 Ampicillin has to be taken more frequently than amoxicillin Phenoxymethylpenicillin is effective against Streptococcus pneumoniae, but lacks efficacy against Haemophilus influenzae Cephalosporins are not usually recommended in the first-line treatment of AOM. Although recent RCTs have confirmed the efficacy of ceftriaxone, it is taken as an intramuscular injection, which is inconvenient for use in primary care. In addition, cephalosporins are not suitable for people with allergies to penicillin, who may be crosssensitive to cephalosporins Quinolones are contraindicated in children under 16 years of age. In addition, they should only be used in adults when the organism sensitivity to them is known, as there are growing concerns about the development of resistance to these drugs in the community. If used, a quinolone with enhanced anti-pneumococcal activity should be selected (e.g. moxifloxacin) Trimethoprim and co-trimoxazole are not recommended, owing to safety and resistance issues. PATIENT INFORMATION The ear infection is still present. An antibiotic is likely to clear the infection. Amoxicillin is the common antibiotic used for ear infections. Alternatives are: o Co-amoxiclav, if you have already had a course of amoxicillin that has not worked (some bacteria are resistant to some antibiotics) o Erythromycin or clarithromycin for people allergic to penicillin Antibiotics may cause side-effects such as diarrhoea or feeling sick. Painkillers such as paracetamol or ibuprofen are an important treatment in addition to antibiotics. Use regularly until the pain eases. © NHS Institute for Innovation and Improvement 12 ACUTE SINUSITIS If the infection is suspected to be of dental origin, refer to a dentist. General management Prescribe analgesia to reduce pain and temperature. Paracetamol or ibuprofen are usually sufficient. Codeine can be added if required. Investigate? Routine diagnostic tests are not helpful in the initial assessment of acute sinusitis. Plain X-rays, blood tests, nasal swabs, sinus puncture, and transillumination of the sinuses are of limited value in primary care, and are not recommended. Referral for computed tomography is not routinely recommended. Intranasal decongestants may give additional relief to antibiotic treatment in the short term. Other symptomatic treatments are not generally recommended. Antibiotics Antibiotics should not be prescribed routinely. Prescribe if: Symptoms have persisted for 7 days or more. Symptoms are severe, or are deteriorating significantly. If an antibiotic is indicated, prescribe: Amoxicillin as the first-line antibiotic. Doxycycline, erythromycin or clarithromycin, if amoxicillin is unsuitable (e.g. allergy to penicillin) Erythromycin, in pregnant or breastfeeding women. Follow-up advice Routine follow-up is not required in people whose symptoms resolve with or without treatment. If a person is not treated with an antibiotic: Advise review if symptoms get worse or are not improving within 7 days. Consider the use of a first-line antibiotic. If a person is being treated with an antibiotic: Advise review if symptoms are not improving within 72 hours or if the antibiotic is poorly tolerated (e.g. vomiting). Consider the use of a second-line antibiotic Practical prescribing points Ibuprofen: as with other nonsteroidal anti-inflammatory drugs, ibuprofen may worsen or precipitate gastrointestinal haemorrhage, asthma, hypertension, renal impairment, or cardiac failure. Avoid if there is a history of peptic ulcers, and avoid in pregnant women. Doxycyline: contraindicated in pregnancy, breastfeeding, porphyria, and in children aged under 12 years. Use with caution in people with hepatic impairment. Doxycycline may cause photosensitivity reactions (avoid exposure to excessive sunlight or sunlamps). Intranasal decongestants can cause severe rebound effects, and should not be used continuously for more than 7 days. Analgesia Paracetamol is an effective and safe analgesic and antipyretic drug. Ibuprofen is an effective alternative to paracetamol, with a longer duration of action. Codeine (in combination with paracetamol): higher-dose codeine is included for use for up to a few days with regular paracetamol for additional pain relief. Codeine 60 mg combined with paracetamol has been shown to provide more pain relief than either codeine 60 mg alone or paracetamol 1000 mg Intranasal decongestants Intranasal decongestants are effective in relieving nasal congestion in the short term, and may be of benefit in sinusitis. They should not be used for more than a week because of the risk of rebound congestion on cessation of treatment Ephedrine and xylometazoline are sympathomimetic drugs, both available on prescription Should I refer or investigate? Refer? Admit if there are: Suspected complications (e.g. periorbital infection). Urgently refer to an Ear, Nose and Throat (ENT) department if there is a: Suspected sinonasal tumour (persistent unilateral symptoms, such as bloodstained discharge, crusting, or facial swelling). Consider ENT referral for: Unremitting or progressive facial pain. Shared decision making Sinusitis (infected sinus) is common, and often follows a cold. Many people with sinusitis do not require any treatment. The immune system usually clears away the infection. 13 Painkillers may be needed: Amoxicillin 500mg capsules. Take one capsule three times a day for 7 days. Supply 21 capsules. Paracetamol will usually be sufficient. Ibuprofen is an alternative. Codeine can be added if paracetamol alone is not sufficient. 1st-line: penicillin allergy Doxycycline capsules: 100mg once a day Age from 16 years onwards Doxycycline 100mg capsules.

Clarithromycin suspension: 250mg twice a day Age from 10 years to 11 years 11 months Clarithromycin 250mg/5ml susp. Take one 5ml spoonful twice a day for 7 days. Supply 70 ml. Clarithromycin tablets: 250mg twice a day Age from 12 years onwards Clarithromycin 250mg tablets. Take one tablet twice a day for 7 days. Supply 14 tablets. Decongestants may help to ease symptoms. You should not use decongestant drops or sprays for more than 5–7 days as a 'rebound' blockage of the nose may occur. Antibiotics are not usually needed. They may be advised if symptoms are severe, getting worse, or last longer than 7 days. Amoxicillin is recommended as the first-line antibiotic in most people. It is active against most of the causative organisms implicated in acute bacterial sinusitis, and has been shown to be effective in clinical trials. It is inexpensive and generally well tolerated Doxycycline is an alternative to amoxicillin if there is a true allergy to penicillin. It has similar antibacterial activity to amoxicillin and, unlike other tetracyclines, only requires once-daily administration. It is contraindicated in children under the age of 12 years Erythromycin or clarithromycin are alternatives to amoxicillin when there is a true allergy to penicillin. Both drugs are active against most of the causative organisms implicated in sinusitis, although resistance to Haemophilus influenzae is increasing. Clarithromycin has fewer gastrointestinal adverse effects than erythromycin [Erythromycin is less effective against Haemophilus influenzae, but is recommended for use in pregnant or breastfeeding women due to its safety record. 1st-line antibiotic: amoxicillin Amoxicillin s/f suspension: 125mg three times a day Age from 1 year to 1 year 11 months Amoxicillin 125mg/5ml s/f susp.

Take one tablet four times a day for 7 days. Supply 28 tablets. 14 Intranasal decongestants Ephedrine 0.5% nose drops Age from 1 year onwards Ephedrine 0.5% nose drops. Put one to two drops into each nostril up to four times a day when required for nasal blockage. Do not use for more than 7 days. Supply 10 ml. Xylometazoline 0.05% nose drops Age from 1 year to 11 years 11 months Xylometazoline paed nose drops. Put one to two drops into each nostril once or twice a day when required for nasal blockage. Do not use for more than 7 days. Supply 10 ml. Xylometazoline 0.1% nose drops Age from 12 years onwards Xylometazoline 0.1% nose drops. Put two to three drops into each nostril 2 to 3 times a day when required for nasal blockage. Do not use for more than 7 days. Supply 10 ml. Co-trimoxazole should only be used under exceptional circumstances, according to a recommendation from the Committee on Safety of Medicines Other drugs for symptomatic treatment Fixed-dose combination analgesics containing weak opioids (e.g. codeine) are not recommended, as they do not allow titration of the most effective and safe analgesic dose to match the person's requirements. Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs), other than ibuprofen, are excluded because of their greater adverse-effect profiles. In addition, aspirin should not be used in children under the age of 16 years. Oral decongestants are not as effective as intranasal decongestants, can cause systemic adverse effects, and may interact with other medications. Intranasal corticosteroids are unlikely to be beneficial in the treatment of acute sinusitis, as they take time (probably at least 7 days) to exert their effects. Antihistamines (oral or intranasal) are not included, as they are unlikely to reduce symptoms of bacterial sinusitis (although they may provide some relief if a person has underlying allergic symptoms). Mucolytics are not included, as they have not been shown to be beneficial in acute sinusitis. Drugs not included Antibiotics Penicillins other than amoxicillin are not included, as none have been shown to have any additional benefits compared with amoxicillin: Phenoxymethylpenicillin has been recommended previously by national guidelines . However, it has not been studied as extensively as amoxicillin, and is less active against Haemophilus influenzae and Moraxella catarrhalis. Co-amoxiclav is recommended for second-line treatment. Tetracyclines other than doxycycline are not included. Oxytetracycline has been recommended previously in national guidelines but requires four doses a day, which may reduce compliance Cephalosporins are not recommended for the first-line treatment of acute sinusitis. Older cephalosporin drugs are not effective against beta-lactamase-producing strains such as H influenzae, whereas newer cephalosporins may require parenteral administration and are more suited for second-line treatment . In addition, people who are allergic to penicillin may be cross-sensitive to cephalosporins Quinolones are not recommended for the first-line treatment of acute sinusitis. To reduce the potential for the development of antibiotic resistance, they should be reserved for use when other antibiotics have proved ineffective]. In addition, newer fluoroquinolones have not been shown to be more effective than more conventional antibiotics Metronidazole is effective against anaerobic bacteria, which are usually associated with sinusitis secondary to dental infection. © NHS Institute for Innovation and Improvement 15 SINUSITIS TREATMENT FAILURE Follow up advice Routine follow-up is not required in people whose symptoms resolve with second-line antibiotic treatment. People should seek medical advice if their symptoms get worse or are not improving after second-line antibiotic treatment (or treatment with an alternative first-line antibiotic). Consider seeking specialist advice. An alternative second-line antibiotic could be tried, if appropriate, if symptoms are stable. Reassess for other possible diagnoses, consider the possibility of complications, and check compliance with treatment. Prescribe a second-line antibiotic (co-amoxiclav) if: An initial course of antibiotics has proved ineffective. Symptoms are not improving after 72 hours. If there is a true allergy to penicillin, consider prescribing a first-line antibiotic that has not been used previously. Use erythromycin or clarithromycin if doxycycline was used first. Use doxycyline if a macrolide was used first. Continue analgesia to reduce pain and temperature. Paracetamol or ibuprofen are usually sufficient, but codeine can be added if required. Consider recommending an intranasal decongestant if this has not been used previously. Other treatments should not be initiated without specialist advice. Analgesia Paracetamol is an effective and safe analgesic and antipyretic drug. Ibuprofen is an effective alternative to paracetamol, with a longer duration of action. Codeine (in combination with paracetamol): higher-dose codeine is included for use for up to a few days with regular paracetamol for additional pain relief.

Admit if there are: Suspected complications (e.g. periorbital infection). Urgently refer to an Ear, Nose and Throat (ENT) department if there is a: Suspected sinonasal tumour (persistent unilateral symptoms, such as bloodstained discharge, crusting, or facial swelling). Consider an ENT referral if: Second-line antibiotic treatment has been tried (or erythromycin in pregnant women), and there are no alternative antibiotic options. There is unremitting or progressive facial pain. If the infection is suspected to be of dental origin, refer to a dentist. Antibiotics Co-amoxiclav is indicated as second-line treatment when amoxicillin has failed. It is a combination product consisting of amoxicillin and clavulanic acid. It is effective against beta-lactamase-producing bacteria, including Moraxella catarrhalis and resistant strains of Streptococcus pneumoniae. Co-amoxiclav is as effective as other antibiotics that are betalactamase resistant (e.g. third-generation cephalosporins), is taken orally, and is inexpensive. Doxycycline is an alternative to co-amoxiclav if there is a true allergy to penicillin and it has not been used before. It has similar antibacterial activity to amoxicillin and, unlike other tetracyclines, only requires oncedaily administration. It is contraindicated in children under the age of 12 years Erythromycin or clarithromycin are recommended when there is a true allergy to penicillin and a macrolide has not been used before.

Chronic sinusitis is defined as symptoms persisting for more than 90 days. In all people: Prescribe analgesia to reduce pain (if necessary). Paracetamol or ibuprofen is usually sufficient, and codeine can be added if required. Identify predisposing factors, and manage these (where possible): o Allergies — o Anatomical abnormalities (e.g. nasal septal deviation) — consider referral. o Pre-existing asthma — optimize asthma control. o Dental infection — give advice on good dental hygiene, and ask the person to see a dentist promptly if a dental infection is suspected. Smoking — advise the person to stop smoking and avoid exposure to passive smoking. o Divers with nasal or sinus pathology — advise on the potentially serious consequences of sinus barotrauma, and refer for specialist advice. In people with recurrent sinusitis: Treat as an acute episode and consider referral for Ear, Nose and Throat (ENT) assessment.

Treat any skin condition such as eczema, psoriasis. Consider using acidifying ear drops or spray (no prescription is needed). Initial management When should I investigate someone with acute diffuse otitis externa? Investigations are rarely useful. However, if treatment fails or otitis externa recurs frequently, consider sending an ear swab for bacterial and fungal microscopy and culture. Which people with acute diffuse otitis externa should be followed up? Consider follow up for people with diabetes or compromised immunity, or with cellulitis which has spread outside the auditory canal. How should I treat acute diffuse otitis externa? Remove or treat any precipitating or aggravating factors. Prescribe or recommend an analgesic for symptomatic relief. Paracetamol or ibuprofen are usually sufficient. Codeine can provide additional analgesia for severe pain. Prescribe a topical ear preparation for 7 days. Options include preparations containing: Both a non-aminoglycoside antibiotic and a corticosteroid e.g. flumetasone–clioquinol (Locorten–Vioform®) ear drops. Both an aminoglycoside antibiotic and a corticosteroid (contraindicated if the tympanic membrane is perforated). Topical preparations containing only an antibiotic (gentamicin ear drops are contraindicated if the tympanic membrane is perforated). If there is sufficient earwax or debris to obstruct topical medication, consider cleaning the external auditory canal (may require referral). If there is extensive swelling of the auditory canal, consider inserting an ear wick (may require referral). Provide appropriate self-care advice. When should I refer or seek specialist advice for someone with acute diffuse otitis externa? Admit urgently if malignant otitis is suspected. Consider seeking specialist advice if: Symptoms have not improved despite treatment and treatment failure is unexplained. Treatment with a quinolone is indicated. Consider referral to secondary care if there is: Extensive cellulitis. Extreme pain or discomfort. Considerable discharge or extensive swelling of the auditory canal, and microsuction or ear wick insertion is required. How should I manage treatment failure of acute diffuse otitis externa? Review the diagnosis and exclude and manage other conditions. Assess and manage ongoing triggers (e.g. exposing ears to moisture, trauma to the ear canal by attempts to clean or scratch it). Assess and manage any compliance problems. Assess and manage factors that would impede delivery of topical medication to affected areas. If contact dermatitis due to neomycin or other aminoglycoside is suspected, consider switching to a preparation which does not contain an aminoglycoside. If there are systemic signs of infection, or if the infection is spreading outside the ear canal, prescribe an oral antibiotic (i.e. flucloxacillin; or erythromycin if penicillin sensitive; or clarithromycin if erythromycin and flucloxacillin are both contraindicated). If these measures have been tried, or are not applicable: Consider culturing a specimen of the ear canal to identify fungi and resistant bacteria. Consider the possibility of a fungal infection and treat with topical preparation containing an antifungal, such as clotrimazole 1% ear What methods should I consider for cleaning the external auditory canal in someone with acute diffuse otitis externa? Gentle syringing or irrigation — to remove debris, provided that the tympanic membrane is intact; regarded as controversial by some experts. Dry swabbing — to gently mop out thin secretions from the external auditory canal. Microsuction — if irrigation and swabbing are ineffective or inappropriate. Microsuction will usually require referral to secondary care. What advice should I give about preventing otitis externa? Avoid damaging the external ear canal. Keep the ears dry and clean. Avoid ear drops containing neomycin if of an allergic disposition. 20 drops (Canesten®), or flumetasone pivalate 0.02%, clioquinol 1% ear drops (Locorten-Vioform®). Otherwise seek specialist advice. . 1st-line antibiotic: flucloxacillin for 7 days Flucloxacillin oral solution: 62.5mg four times a day Age from 3 months to 1 year 11 months Flucloxacillin 125mg/5ml oral solution.

Referral for investigation should be considered for women with recurrent urinary tract infection (UTI), or who persistently fail to respond to treatment. Referral guidelines for suspected cancer published by the National Institute for Health and Clinical Excellence [NICE, 2005] recommend urgent referral to a team specializing in the management of urological cancer, depending on local arrangements, for people: Of any age with painless macroscopic haematuria: o If there are also symptoms suggestive of UTI, culture the urine and treat any infection. If infection is not confirmed, or if haematuria persists after treatment of infection, refer urgently. Aged 40 years or older who present with recurrent or persistent UTI associated with haematuria. Aged 50 years or older who are found to have unexplained microscopic haematuria. With an abdominal mass identified clinically or on imaging that is thought to arise from the urinary tract. Scenario: Cystitis in otherwise healthy women who are not pregnant Follow local guidelines if they recommend different antibiotics. Take local rates of bacterial resistance into account when choosing antibiotics. The following apply to otherwise healthy women who are not pregnant, and who have a suspected lower urinary tract infection (UTI). If there is vaginal irritation or discharge, consider other diagnoses. (Bacterial vaginosis, Candida - female genital, and Chlamydia). If UTI is diagnosed and there is fever and flank or loin or back pain or tenderness, upper UTI is likely and antibiotic treatment for 7 days is indicated. If the symptoms are mild, the woman may wish to consider not taking an antibiotic, as UTIs usually resolve spontaneously in a few days. If lower UTI is suggested by multiple typical symptoms and signs (e.g. dysuria, frequency, suprapubic discomfort), treat empirically with trimethoprim or nitrofurantoin for 3 days. If lower UTI is suggested by only one or vague symptoms and signs, dipstick-test the urine. o If the dipstick test is positive for nitrite and leucocyte esterase, treat empirically with trimethoprim or nitrofurantoin for 3 days. o Otherwise, use clinical judgement to decide on management. Consider culturing the urine to help make a definitive diagnosis. If symptoms are mild, consider waiting to confirm UTI with culture results before treating, otherwise, treat empirically with trimethoprim or nitrofurantoin for 3 days. If trimethoprim has been taken in the past 3 months, some clinicians recommend using an alternative antibiotic for empirical treatment. Treat pain and raised temperature with paracetamol or ibuprofen. Investigate? Urine dipstick — use only in women with vague or few typical symptoms of cystitis (e.g. dysuria, frequency, suprapubic discomfort). Positive for nitrite and leucocyte esterase (LE): diagnose urinary tract infection. Negative for nitrite and/or LE: consider urine culture to help diagnosis. Urine culture is indicated when: Cystitis is suspected, but the dipstick is negative for nitrites or leucocytes. Treatment has failed. Symptoms recur. Investigations for sexually transmitted diseases should be considered in sexually active women (e.g. chlamydia screen). Follow Up Follow up according to the clinical situation. Review is recommended if symptoms have not resolved with treatment. If urine has been cultured, check the results and ensure antibiotic treatment is appropriate. Practical prescribing points Nitrofurantoin should not be used in people known to be glucose-6phosphate dehydrogenase (G6PD)-deficient. Ibuprofen, as with other nonsteroidal anti-inflammatory drugs (NSAIDs), may worsen or precipitate gastrointestinal haemorrhage, asthma, hypertension, renal impairment, or cardiac failure. Avoid if there is a history of peptic ulcers. Should I refer or investigate? 23 Drugs included Trimethoprim is the antibiotic of choice for empirical treatment in uncomplicated urinary tract infection (UTI). It is effective, safe, and inexpensive. It should not be used if the patient has a history of recurrent infections resistant to this drug, or has recently (i.e. within about 3 months) taken trimethoprim. Nitrofurantoin is a useful alternative antibiotic, effective against most urinary pathogens. For most people the standard tablet formulation is suitable. The macrocrystalline capsules and the twice-daily modifiedrelease formulation may be better tolerated if nausea is troublesome, and are offered as alternatives. Age from 14 years onwards Nitrofurantoin 50mg capsules. Take one capsule four times a day for 3 days. Supply 12 capsules. Patient Information: This medicine may cause your urine to turn more yellow than normal. Passing urine regularly may help to relieve symptoms - do not 'hang on' if you need to go to the toilet. Also wipe from front to back to avoid transferring germs. Nitrofurantoin m/r capsules: 100mg twice a day Age from 14 years onwards Nitrofurantoin 100mg m/r caps. Take one capsule twice a day for 3 days. Supply 6 capsules. Patient Information: This medicine may cause your urine to turn more yellow than normal. Passing urine regularly may help to relieve symptoms - do not 'hang on' if you need to go to the toilet. Also wipe from front to back to avoid transferring germs. Paracetamol is an effective and safe analgesic and antipyretic. Ibuprofen is an effective alternative to paracetamol if there are no contraindications. Drug rationale Drugs not included In general, antibiotics that are not used for first-line empirical treatment of lower UTI are not included. Penicillins such as amoxicillin are unsuitable for treatment unless culture results indicate that the bacterium is sensitive. Around 50% of urinary pathogens are amoxicillin-resistant. First-generation cephalosporins (e.g. cefalexin) have similar antibiotic sensitivities and adverse-effect profiles, and are more expensive. There is greater relapse with cephalosporins than with trimethoprim Co-amoxiclav, quinolones, and pivmecillinam should be reserved for second-line treatment, in order to limit the development of resistance and to preserve their efficacy. Urine alkalinizing agents are of unproven benefit and there is some evidence that they do not relieve the symptoms of cystitis © NHS Institute for Innovation and Improvement Shared decision making An antibiotic for 3 days is the common treatment for women with cystitis. Paracetamol or ibuprofen will help with pain or discomfort. 'Drink plenty of fluid' is common advice, in order to 'flush out the bladder'. However, this is unproven, and passing urine more often may be unpleasant. If symptoms have not gone or nearly gone after 3 days, consult a doctor. If cystitis becomes a recurring problem, consult a doctor. Prescriptions 1st-line antibiotic for 3 days Trimethoprim tablets: 200mg twice a day Age from 14 years onwards Trimethoprim 200mg tablets. Take one tablet twice a day for 3 days. Supply 6 tablets. Patient Information: Passing urine regularly may help to relieve symptoms - do not 'hang on' if you need to go to the toilet. Also wipe from front to back to avoid transferring germs. Nitrofurantoin tablets: 50mg four times a day Age from 14 years onwards Nitrofurantoin 50mg tablets.

Passing urine regularly may help to relieve symptoms - do not 'hang on' if you need to go to the toilet. Also wipe from front to back to avoid transferring germs. Nitrofurantoin capsules: 50mg four times a day 24 Scenario: Recurrent cystitis in non-pregnant women Follow local guidelines if they recommend different antibiotics. Take local rates of bacterial resistance into account when choosing antibiotics. Treat acute episodes of recurrent urinary tract infection (UTI) in a woman with an analgesic/antipyretic and a 3-day course of trimethoprim or nitrofurantoin, or an antibiotic to which the organism is sensitive. Treatments that are not recommended include: Oestrogen use for the routine prevention of recurrent UTI in postmenopausal women. Seek specialist advice before prescribing oestrogen treatment for preventing recurrent cystitis in a postmenopausal woman. Practical prescribing points Nitrofurantoin should not be used in people who are known to be glucose-6-phosphate dehydrogenase (G6PD)-deficient. Ibuprofen, as with other nonsteroidal anti-inflammatory drugs (NSAIDs), may worsen or precipitate gastrointestinal haemorrhage, asthma, hypertension, renal impairment, or cardiac failure. Avoid if there is a history of peptic ulcers. Cranberry extracts: Cranberry juice has been reported to interact with warfarin, and the Committee on Safety of Medicines (CSM) has advised that people taking warfarin should avoid cranberry products [ Cranberry extracts have not been studied in older women and their safety in this population is not established. Cranberry products are not available on the NHS, but are readily available from pharmacies, health food shops, herbalists, and supermarkets. However, cranberry products are not regulated medicines, and preparations are not standardized. Cranberry capsules may be more convenient than juice; higher doses may be more effective than lower doses. Comprehensively assess the problem: Review urine culture results, or, if not available, send urine for culture during an acute episode. Assess clinical presentations (mild, moderate, or severe illness). Review medical and surgical history (may suggest risk factors — e.g. stones, papillary necrosis, vesicoureteric reflux). Review recent antibiotic treatment (bacterial resistance is more probable). Assess whether previous antibiotics have been taken as prescribed, and note that some clinicians recommend avoiding repeating trimethoprim within 3 months. Check that there are no features suggestive of cancer. Consider the following management options if there are three or more episodes per year: Patient-initiated antibiotics for new episodes (i.e. 'stand-by antibiotics'), or Professional-initiated antibiotics for new episodes (i.e. usual treatment when required), or Continuous antibiotic prophylaxis: o Low dose for 6 months o Repeat course if infection recurs o If infection occurs while taking prophylactic antibiotics, send the urine for culture before starting treatment with a different antibiotic. Restart prophylaxis with an antibiotic that is active against the infecting organism. A trial of cranberry extract (available from shops but not the NHS) If recurrence is related to sexual intercourse, consider the above options and: o Single-dose antibiotic prophylaxis — to be taken before or soon after intercourse o Advising change of contraceptive method if diaphragm (female condom) or spermicide is being used o Advising voiding after intercourse o Advising use of a lubricant if symptoms seem to be due to trauma rather than infection Refer for specialist assessment if: Recurrent cystitis fails to respond to the above measures There are features suggestive of cancer Referral guidelines for suspected cancer published by the National Institute for Health and Clinical Excellence [NICE, 2005] recommend urgent referral to a team specializing in the management of urological cancer, depending on local arrangements, for people: Of any age with painless macroscopic haematuria: If there are also symptoms suggestive of urinary tract infection (UTI), culture the urine and treat any infection. If infection is not confirmed, or if haematuria persists after treatment of infection, refer urgently. Aged 40 years or older who present with recurrent or persistent UTI associated with haematuria. Aged 50 years or older who are found to have unexplained microscopic haematuria. 25 With an abdominal mass identified clinically or on imaging that is thought to arise from the urinary tract. Penicillins such as amoxicillin are unsuitable for empirical treatment because about 50% of all urinary pathogen isolates are amoxicillin-resistant. First-generation cephalosporins (e.g. cefalexin) have similar antibiotic sensitivities and adverse-effect profiles, and are more expensive. There is greater relapse with cephalosporins than with trimethoprim Co-amoxiclav, quinolones, and pivmecillinam should be reserved for secondline treatment, in order to limit the development of resistance and to preserve their efficacy. Topical oestrogens are not recommended for the routine prevention of recurrent urinary tract infection in postmenopausal women, as they are less effective than prophylactic antibiotics Urine alkalinizing agents are of unproven benefit and there is some evidence that they do not relieve the symptoms of cystitis Investigate? Urine culture is needed to confirm a microbial cause for at least one episode of urinary tract infection (before commencing long-term prophylactic treatment). Urine culture and sensitivity tests are helpful to manage breakthrough infections. Urinary tract imaging is rarely indicated. Cystoscopy is rarely indicated. If prophylactic antibiotics are prescribed, follow-up after 6 months (or sooner if clinically indicated). Shared decision making Some women tend to have recurrent bouts of cystitis. A kidney or bladder problem is sometimes the cause, but usually the reason for recurring cystitis is not clear. Some women tend to get cystitis after having sex. In these circumstances the chance of cystitis can be reduced by: Changing the method of contraception if either spermicides or a diaphragm are used. Going to the toilet and fully emptying the bladder after sex. Lubrication — this helps if symptoms are due to irritation. Taking a single dose of an antibiotic after sex. Antibiotic prevention is an option in other circumstances. This means taking a low dose of an antibiotic every day (or sometimes three times a week). It is best to take the antibiotic at bedtime. It is usual to take a course for 3–6 months and then to review the situation. A change of antibiotic may be needed if cystitis recurs. Cranberry extracts: Cranberry extracts can help prevent cystitis. However: Cranberry extracts have not been shown to be safe in older people or in young children. Cranberry is unsafe to take with certain medicines, for example warfarin. Cranberry extracts can be bought from supermarkets, chemists, and health stores. High-dose capsules may be better than low-dose capsules or juice. If a urine culture test is done, telephone for the results in 2 or 3 days. Ask if it is necessary to change the antibiotic. Standby antibiotics (3 days) Standby prescriptions are offered for the woman to initiate when symptoms recur. Trimethoprim is effective against most urinary tract pathogens, and safe and inexpensive. It should not be used if the patient has recently taken trimethoprim (some clinicians recommend avoiding repeating trimethoprim within 3 months), or has a history of recurrent infections resistant to this drug. Nitrofurantoin is a useful alternative antibiotic, effective against most urinary pathogens. For most people the standard tablet formulation is suitable. The macrocrystalline capsules and the twice-daily modifiedrelease formulation may be better tolerated if nausea is troublesome, and are offered as alternatives. Trimethoprim tablets: 200mg twice a day Age from 14 years onwards Trimethoprim 200mg tablets. Take one tablet twice a day for 3 days. Supply 6 tablets.

Nitrofurantoin m/r capsules: 100mg twice a day Age from 14 years onwards Nitrofurantoin 100mg m/r caps. Take one capsule twice a day for 3 days. Supply 6 capsules. Drugs not included 26 against the use of trimethoprim for women who are pregnant or planning to become pregnant. Nitrofurantoin should not be prescribed if the mother is glucose-6phosphate dehydrogenase (G6PD)-deficient. It can otherwise be used during pregnancy, but should not be taken near term as it can cause haemolysis in the fetus. Cefalexin is a broad-spectrum antibiotic and is therefore more likely to cause diarrhoea and vaginal thrush. In high dosages cefalexin may cause diarrhoea, but can be taken with food or milk to try to avoid stomach upset. Rarely, cefalexin may cause pseudomembranous colitis. If pseudomembranous colitis is suspected, stop cefalexin immediately. During pregnancy — cefalexin has not been shown to cause harm to the fetus. Women can continue to breastfeed while taking cefalexin. Low concentrations are present in breast milk, which may cause changes to the bacteria in the infant's gastrointestinal tract. Scenario: Cystitis and asymptomatic bacteriuria in pregnancy Follow local guidelines if available. Take local rates of bacterial resistance into account when choosing antibiotics. Asymptomatic bacteriuria: Screen for asymptomatic bacteriuria on the first antenatal visit by sending urine for culture. If symptomatic bacteriuria is found, confirm its presence with a second urine culture. Treat confirmed asymptomatic bacteriuria for 7 days with an antibiotic to which the organism is sensitive: o First-line options when the sensitivities are known are trimethoprim, nitrofurantoin, amoxicillin, and cefalexin o Send urine cultures to screen for asymptomatic bacteriuria at every antenatal visit until delivery. o Treat pain and raised temperature with paracetamol. Acute lower urinary tract infection: Send urine for culture. Treat with an appropriate antibiotic for 7 days. First-line choices for empirical treatment are trimethoprim, nitrofurantoin, cefalexin, or amoxicillin. Review progress with culture results and adjust treatment accordingly. Send urine cultures to screen for asymptomatic bacteriuria 7 days after completion of treatment. Treat pain and raised temperature with paracetamol. Refer? Admit if there is systemic illness or if pyelonephritis is suspected. Refer if urine culture is still positive 1–2 weeks after treatment. Refer if urinary tract infection recurs in pregnancy: obtain specialist advice with regard to prophylactic antibiotics. Investigate? Culture urine before starting antibiotics. Empirical treatment may need to be modified in the light of the results. Samples taken for culture should be taken mid-stream, placed in a preservative-containing bottle or refrigerated, and cultured as soon as possible. Practical prescribing points Trimethoprim is a folate antagonist, and there have been concerns over its use during pregnancy, as it may limit the availability of folic acid to the fetus and impair normal development. In women with a low folate status (i.e. women with established folic acid deficiency or low dietary intake, or in those already taking known folate antagonists such as antiepileptics and proguanil), trimethoprim should be avoided unless the woman is also taking a folate supplement. In women with normal folate status, short-term use of trimethoprim is unlikely to induce folate deficiency. Note: women who are pregnant, or at risk of pregnancy, should be taking folic acid until week 12 of their pregnancy in order to prevent neural tube defects in the fetus. However, the BNF cautions against the use of trimethoprim in the first trimester of pregnancy because the manufacturers recommend that it not be used then. The manufacturer's information leaflet also advises Follow-up advice Review according to the clinical situation, (for example, at around 72 hours) to ensure the individual is responding to treatment and to check the results of the urine culture. After treatment of acute lower urinary tract infection, repeat the urine culture 7 days after an antibiotic course has been completed. After confirmed asymptomatic bacteriuria has been treated, send urine cultures to screen for asymptomatic bacteriuria at every antenatal visit until delivery. If a group-B streptococcus is isolated, inform the antenatal care service, as prophylactic antibiotics may be indicated during labour and delivery. 27 Cefalexin tablets: 500mg twice a day Age from 14 years to 59 years 11 months Cefalexin 500mg tablets.

Take one capsule twice a day for 7 days. Supply 14 capsules. Drugs included Amoxicillin is recommended only if the organism is known to be sensitive. Penicillins are not associated with any increased risk to the fetus. Cefalexin is a first-generation cephalosporin. It is not associated with any increased risk to the fetus and is effective against most urinary pathogens. Trimethoprim can be used during pregnancy except in women who are folate deficient, or who are taking folate antagonists (unless a folate supplement is taken). It should not be used if the woman has recently taken trimethoprim (some clinicians recommend avoiding repeating trimethoprim within 3 months), or has a history of recurrent infections resistant to this drug. Nitrofurantoin is effective against most urinary tract infections. It should not be prescribed if the mother is glucose-6-phosphate dehydrogenase (G6PD)-deficient. Nitrofurantoin can otherwise be used in pregnancy, but may cause haemolysis in a G6PD-deficient infant if used close to term. For most people the standard tablet formulation is suitable. The macrocrystalline capsules and the twice-daily modified-release formulation may be better tolerated if nausea is troublesome, and are offered as alternatives. Paracetamol is an effective and safe analgesic and antipyretic. Drugs not included Quinolones are not recommended in any trimester because of safety concerns. Co-amoxiclav is not generally recommended for use during pregnancy, as there are insufficient data on the safety of clavulanic acid. It should only be used if thought to be essential. First-generation cephalosporins other than cefalexin have similar antibiotic sensitivities and adverse-effect profiles, and are more expensive. Second-generation cephalosporins are not as well absorbed orally as first-generation cephalosporins, have a greater incidence of gastrointestinal adverse effects, and are more expensive than the firstgeneration agents. Third-generation cephalosporins generally require parenteral administration and are reserved for use in secondary care for serious infections. Pivmecillinam is not known to be teratogenic, but it is not recommended in pregnancy because of insufficient safety data. Urine alkalinizing agents are of unproven benefit and there is some evidence that they do not relieve the symptoms of cystitis. Sodium citrate should be avoided in pregnancy because of the high sodium content. 1st-line antibiotic for 7 days Trimethoprim tablets: 200mg twice a day Age from 14 years to 59 years 11 months Trimethoprim 200mg tablets.

A course of an antibiotic is the usual treatment for pregnant women with a urine infection. Paracetamol will help with pain or discomfort. (Ibuprofen is best avoided during pregnancy.) Usually a urine culture test will be done. Telephone for the result after 3 days. Ask if it is necessary to change the antibiotic treatment. 'Drink plenty of fluid' is common advice, to 'flush out the bladder'. However, this is unproven, and passing urine more often may be unpleasant. Your urine should be tested one week after you finish the antibiotic, to check that the infection has gone. Regular urine checks throughout pregnancy are usual. © NHS Institute for Innovation and Improvement 29 Acute cystitis treatment failure Follow local guidelines if they recommend different antibiotics. Take local rates of bacterial resistance into account when choosing antibiotics. The following apply to otherwise healthy women who are not pregnant, with a suspected lower urinary tract infection that has failed to respond to first-line treatment. If urine culture results are available, use the sensitivity report to guide choice of a different antibiotic to which the organism is sensitive. Otherwise: Send a urine sample for culture. If symptoms are mild, wait for sensitivity results to guide choice of antibiotic. If symptoms are particularly troublesome: o Change to a different first-line antibiotic (trimethoprim or nitrofurantoin), or o Consider use of a second-line antibiotic (i.e. cefalexin, coamoxiclav, a quinolone, or pivmecillinam). Paracetamol or ibuprofen can be used to treat pain and high temperature. Of any age with painless macroscopic haematuria: o If there are also symptoms suggestive of UTI, culture the urine and treat any infection. If infection is not confirmed, or if haematuria persists after treatment of infection, refer urgently. Aged 40 years or older who present with recurrent or persistent UTI associated with haematuria. Aged 50 years or older who are found to have unexplained microscopic haematuria. With an abdominal mass identified clinically or on imaging that is thought to arise from the urinary tract. Investigate? Urine culture should be obtained whenever treatment has failed. The sample should be taken with care to avoid contamination, placed in a preservative-containing bottle or refrigerated, and cultured as soon as possible. Consider testing for chlamydia and other sexually transmitted diseases in sexually active women. Follow-up advice Review with culture results to ensure that treatment is appropriate. Consider reviewing by telephone. Practical prescribing points Nitrofurantoin should not be used in people who are known to be glucose-6-phosphate dehydrogenase (G6PD)-deficient. Quinolones may cause tendon damage (Committee on Safety of Medicines advice); stop treatment if pain or inflammation of a tendon occurs. They can induce convulsions in people with epilepsy or in those with conditions that predispose to seizures. People concurrently taking nonsteroidal anti-inflammatory drugs (NSAIDs) may also be susceptible. The risks and benefits of prescribing a quinolone should be considered on an individual basis for these people. Ibuprofen, as with other NSAIDs, may worsen or precipitate gastrointestinal haemorrhage, asthma, hypertension, renal impairment, or cardiac failure. Avoid if there is a history of peptic ulcers. Drugs included Where available, sensitivities should guide antibiotic choice. Trimethoprim is effective against most urinary tract pathogens, and safe and inexpensive. It should not be used if the patient has recently (i.e. within about 3 months) taken trimethoprim, or has a history of recurrent infections resistant to this drug. Nitrofurantoin is a useful alternative antibiotic, effective against most urinary pathogens. For most people the standard tablet formulation is suitable. The macrocrystalline capsules and the twice-daily modifiedrelease formulation may be better tolerated if nausea is troublesome, and are offered as alternatives. Cefalexin is a first-generation cephalosporin effective against most urinary pathogens, but there is less relapse with trimethoprim than with cephalosporins Co-amoxiclav is a suitable second-line alternative. It is effective against up to 90% of urinary pathogens. Ciprofloxacin and norfloxacin are recommended as second-line fluoroquinolones. They are effective against most urinary pathogens (only around 5% of pathogens are resistant) and are currently the least expensive of the quinolones available. Other fluoroquinolones (i.e. Refer? Referral for investigation should be considered for women with recurrent urinary tract infection (UTI), or who persistently fail to respond to treatment. Referral guidelines for suspected cancer published by the National Institute for Health and Clinical Excellence [NICE, 2005] recommend urgent referral to a team specializing in the management of urological cancer, depending on local arrangements, for people: 30 ofloxacin, levofloxacin) can be substituted according to local formulary recommendations. Pivmecillinam is highly active against many Gram-negative pathogens and is an appropriate second-line treatment. Paracetamol is an effective and safe analgesic and antipyretic. Drugs not included Amoxicillin should only be used to treat urinary tract infection when the infecting organism has been shown to be sensitive to amoxicillin, as about 50% of all urinary pathogen isolates are resistant to amoxicillin. Urine alkalinizing agents are of unproven benefit and there is some evidence that they do not relieve the symptoms of cystitis [Brumfitt et al, 1990].

Shared decision making Cystitis sometimes does not clear with an antibiotic. This may be because the germ is 'resistant' to the antibiotic (or in some cases, because the cystitis has not been caused by an infection). A urine test is needed to see whether a germ is present, and which germ it is. A second antibiotic will usually work. It is best to wait until the urine result is back to see which germ is present and which antibiotic kills it. Paracetamol or ibuprofen will help with pain or discomfort. Telephone for the result of the urine test in 3 days. Ask if it is necessary to change the treatment. 'Drink plenty of fluid' is common advice, to 'flush out the bladder'. But this is unproven, and passing urine more often may be unpleasant. Consult a doctor if cystitis still does not clear, or becomes a recurring problem. © NHS Institute for Innovation and Improvement 2nd choice antibiotic Cefalexin tablets: 500mg twice a day Age from 14 years onwards Cefalexin 500mg tablets.
