Stronger treatments when OTC relief is not enough
When over-the-counter antihistamines don't fully control your symptoms, prescription options offer stronger relief. Fexofenadine is a potent non-drowsy antihistamine available on prescription in the UK at higher strengths. Steroid nasal sprays like mometasone reduce inflammation, while Dymista combines an antihistamine with a corticosteroid for dual-action nasal relief.
Fexofenadine Strengths
Fexofenadine 120mg is used for general hay fever symptoms, while the 180mg dose is typically prescribed for urticaria or more severe allergic rhinitis. Unlike cetirizine, fexofenadine does not cross the blood-brain barrier, making drowsiness very unlikely.
Nasal Spray Technique
Aim the spray away from the nasal septum (the centre wall of your nose) and breathe in gently. Correct technique ensures the medication reaches the nasal lining where it is most effective.
Dymista Dual Action
Dymista combines azelastine (an antihistamine) with fluticasone (a corticosteroid). It works within 15 minutes and is one of the most effective nasal sprays available for moderate to severe hay fever.
Quick tips
- Start using steroid nasal sprays two weeks before your pollen season for maximum benefit.
- Do not take fexofenadine with fruit juice — it can reduce absorption by up to 36%.
- Mometasone nasal spray can be used alongside oral antihistamines for comprehensive relief.
- If symptoms persist despite treatment, ask your pharmacist or GP about combination therapy.
