Product overview

About Piriton Allergy Tablets

The allergy tablet that works when the modern ones don't quite: chlorphenamine, the classic fast-acting antihistamine for hay fever, pet and dust allergies, hives and itchy rashes — trusted for decades and still the one many households swear by. Pharmacy medicine. 30 tablets, up to three packs per order.

Classic versus modern antihistamines

Cetirizine and loratadine are once-daily and non-drowsy — the sensible default. Chlorphenamine is faster, stronger on skin symptoms like hives and itching, and dosed through the day — at the price of drowsiness. For flare-ups, reactions and nights when itching stops sleep, the classic earns its keep.

How to take

Adults and children 6+ per the pack: one tablet every 4–6 hours, within the daily maximum.

Good to know

The drowsiness is genuine — no driving until you know how it affects you, no alcohol. Sudden severe reactions with swelling or breathing difficulty are 999 territory, not a tablet's.
