Best hay fever tablets UK: antihistamines compared
Which hay fever tablets work best in the UK — non-drowsy vs sedating antihistamines, when to add a nasal spray, and how to start before pollen season.
Hay fever affects roughly 1 in 5 UK adults. Tablet choice matters less than starting early and using the right combination for your symptoms.
Non-drowsy antihistamines (first choice)
Modern once-daily tablets block histamine with minimal sedation — suitable for work, driving and exams. They help:
- Sneezing and runny nose
- Itchy eyes and palate
- General allergy itch
Take consistently through your season rather than only on bad days.
Sedating antihistamines — when they still help
Older antihistamines cause more drowsiness but can help night-time symptoms when itching disrupts sleep. Avoid driving until you know how you respond.
When tablets alone are not enough
Add a steroid nasal spray if:
- Your nose is blocked most days
- You lose smell
- You mouth-breathe at night
Sprays need 2–3 days of regular use before full effect — another reason to start early.
Eye symptoms
Antihistamine eye drops target ocular itch directly when tablets are insufficient.
UK pollen calendar (rough guide)
- Tree pollen: March–May
- Grass pollen: May–July (peak for most sufferers)
- Weed pollen: June–September
Check daily pollen forecasts and increase treatment on high-count days.

Frequently asked questions
What are the best hay fever tablets in the UK?
Non-drowsy once-daily antihistamines are first choice for most adults. Add a steroid nasal spray if congestion is the main problem. Start 1–2 weeks before your pollen season.
Are non-drowsy antihistamines really non-drowsy?
Second-generation antihistamines cause less sedation than older sedating types, but individual response varies — try the first dose when you do not need to drive until you know how you react.
Can I take hay fever tablets every day all season?
Yes — many people take non-drowsy antihistamines daily throughout pollen season. Follow pack instructions and pharmacist advice.
Tablet or nasal spray for hay fever?
Tablets help sneezing and itching; nasal sprays target blocked nose and often work better for moderate-severe rhinitis. Many people use both.
