When to talk to the pharmacist before buying
- You're already on a daily antihistamine and symptoms aren't controlled — we can switch you to a stronger one (some are P-only).
- You have asthma alongside hay fever — uncontrolled allergy can flare asthma; the pharmacist will check your inhaler use.
- You're pregnant or breastfeeding — most antihistamines are safe but some are preferred over others; ask first.
- You're considering antihistamines for a young child — age limits vary by product.
- Symptoms include facial swelling, breathing difficulty, or whole-body hives — this is anaphylaxis territory, call 999 — do not wait for OTC.
Walk in, phone 0113 244 1551, or message WhatsApp.
Always: read the patient information leaflet before taking any medicine. Report any suspected side effects via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk.
