Using Your Pharmacy
What can a pharmacy give me for hay fever?
By Pick My Pharmacy Editorial · Updated 9 July 2026
Antihistamine tablets — compare the ingredient, not the brand
The first-line hay fever treatment for most adults is a once-daily non-drowsy antihistamine, and pharmacies stock three without prescription: cetirizine, loratadine and fexofenadine. Fexofenadine 120mg was prescription-only until 2021 and is now on pharmacy shelves too. The single most useful money-saving habit is to read the active ingredient on the box rather than the brand name: a generic cetirizine tablet is the same medicine as the heavily advertised branded version, often at a tenth of the price — pennies per tablet against £5–£10 for a branded month. Older sedating antihistamines (such as chlorphenamine) still have a place for night-time itching but cause drowsiness, so avoid driving until you know how you respond. Individual response varies, so if one antihistamine doesn't suit you, it's reasonable to try another.
Nasal sprays and eye drops — for symptoms tablets miss
Tablets help sneezing, itching and a runny nose, but they're often not enough on their own for a blocked nose. That's where steroid nasal sprays come in — beclometasone, fluticasone and mometasone are all available over the counter for adults. They dampen the inflammation itself rather than just blocking histamine, but they need a few days of regular daily use before the full effect arrives, which is one reason pharmacists recommend starting before your season rather than mid-flare. Technique matters too — ask the pharmacist to check your spray angle. For itchy, watery eyes that tablets don't settle, antihistamine or sodium cromoglicate eye drops act directly where the symptom is. Many people with moderate hay fever do best on a tablet plus a spray together.
Timing: start before the pollen does
Hay fever treatment works noticeably better started early. Beginning your antihistamine — and especially a steroid nasal spray — one to two weeks before your usual symptom season gives the medicines time to build effect before pollen counts peak. In the UK, tree pollen typically runs March to May, grass pollen (the trigger for most people) May to July, and weed pollen June to September, so knowing which season hits you tells you when to start. Alongside medicines, exposure control genuinely helps: check the daily pollen forecast, keep windows closed on high-count days, shower and change clothes after time outdoors, and a smear of barrier balm around the nostrils can trap pollen before it's inhaled. Taking a non-drowsy antihistamine daily all season is fine for most people.
When hay fever needs a GP instead
Most hay fever is managed entirely at the pharmacy, but some situations warrant a GP review. Book one if your symptoms haven't improved after around two weeks of regular, correctly used treatment; if they run year-round (which may be perennial rhinitis rather than hay fever); or if hay fever is making asthma symptoms worse — that combination needs proper review. GPs can prescribe stronger or combination treatments, and severe cases that resist everything else can be referred for specialist options such as immunotherapy. A pharmacist is the right first stop, though: they can look at what you've already tried, fix technique problems, and tell you honestly whether a GP appointment is warranted. This is general information, not medical advice — speak to a pharmacist or GP about your own symptoms.
People Also Ask
Which hay fever tablet is strongest?
No single over-the-counter antihistamine is best for everyone — cetirizine, loratadine and fexofenadine are all effective, and individual response varies. Fexofenadine is often tried when another hasn't worked well. If one doesn't suit you, switching to another is reasonable; a pharmacist can advise.
Are non-drowsy antihistamines really non-drowsy?
They cause far less sedation than older antihistamines, but a minority of people still feel drowsy — cetirizine slightly more often than loratadine or fexofenadine. Take your first dose when you don't need to drive until you know how you react.
Can I take hay fever tablets every day all season?
Yes — daily use of a non-drowsy antihistamine through the pollen season is common and generally fine. Follow the pack instructions, and speak to a pharmacist or GP if you seem to need them year-round or they aren't controlling your symptoms.
Do I need a prescription for a steroid nasal spray?
Not usually — beclometasone, fluticasone and mometasone sprays are available over the counter for adults with hay fever. Children's use, long-term use and higher-strength versions may still need a prescription, so check with the pharmacist.
