Hay fever/Seasonal Allergic Rhinitis and Conjunctivitis
(adults)
Key Messages
Diagnosis and management of seasonal (spring/summer) allergic
rhinitis/conjunctivitis. For seasonal allergic rhinitis see separate guidelines.
Assessment
Bilateral nasal itching, congestion and rhinorrhoea, sneezing, or bilateral
conjunctivitis.
Differential diagnosis
- Perennial rhinoconjunctivitis (non-seasonal)
- Infective rhinosinusitis
- Non-allergic (eg hormonal, drug-induced, vasomotor) rhinitis
For diagnostic algorithm see
http://www.bsaci.org/Guidelines/Algorithm-RhinitisPCGL.pdf
Red Flags
Unilateral symptoms, polyps, persistent blood stained discharge or persistent
purulent discharge – consider referral to ENT.
Investigations
No investigations recommended prior to referral.
Management
1. Mild symptoms should be treated with oral non-sedating antihistamines at
doses up to twice BNF maximum dosing (cetirizine 10mg, loratadine 10mg, or
fexofenadine 180mg up to twice daily).
2. Moderate-severe symptoms should be treated with intranasal corticosteroid
(eg Beconase, two sprays into each nostril twice daily; consider trying
alternative, eg Nasonex or Avamys) in addition to non-sedating
antihistamines. Consistent daily use of intranasal use is vital, given maximal
effect may not be apparent for at least two weeks.
a. Start antihistamines and intranasal corticosteroids two weeks
before usual symptom onset and continue throughout season
b. Training in appropriate nasal spray technique essential. Guidance is

3. Systemic corticosteroids (in addition to intranasal corticosteroid) at doses of
15-20mg for a maximum of 5 days as a one-off treatment can be used for
severe symptoms uncontrolled on conventional therapy, to control symptoms
during important periods (eg exams or other major events).
4. Topical cromoglicate and nedocromil eyedrops are useful to manage allergic
conjunctivitis.
Consider a concomitant diagnosis of asthma and manage according to guidelines
- Montelukast can be added to conventional therapy in patients with seasonal
allergic rhinitis and concomitant asthma.

Treatment failure should prompt a review of the diagnosis, compliance with therapy
(regular therapy is more effective than “as required” treatment), and intranasal
corticosteroid technique.
Experience from Peninsula Immunology and Allergy Service suggests that 70% of
patients referred with severe symptoms achieve satisfactory symptom control using
non-sedating antihistamines and regular intranasal corticosteroids alone.
