Product overview
About Phenergan 25mg Tablets
The multi-purpose sedating antihistamine: promethazine 25mg, trusted for decades against allergies, hives and itchy rashes, travel sickness, and short-term sleeplessness. A pharmacy pack of 56 tablets.
One active, several jobs
Promethazine blocks histamine hard — that settles allergic reactions from hay fever to pet allergy to nettle rash — and its calming side makes it the classic choice for motion sickness and restless nights. The pack icons say it plainly: travel, sleep, pollen, pets.
How to take
Adults: allergies — 25mg at night, up to 25mg twice daily if needed. Travel sickness — 25mg the night before travelling. Sleeplessness — 25–50mg at bedtime, short courses only. Children's dosing varies by age and use: check the leaflet.
Good to know
This is the drowsy kind of antihistamine by design — modern non-drowsy tablets suit daytime allergy better, but nothing modern beats promethazine when sedation is part of the point. No alcohol, no driving until you know its effect.

Frequently asked questions
Phenergan or a non-drowsy antihistamine?
For daytime hay fever, non-drowsy loratadine or cetirizine wins. Phenergan earns its place when itching ruins sleep, for travel sickness, or when sedation helps.
Can children take it?
From age 5 for some uses at reduced doses — and never for sleep in children without medical advice. Check the leaflet or ask our pharmacist.
How long before travel should I take it?
The night before a long journey, or 1–2 hours before a shorter one. Expect drowsiness — it's part of how it settles motion sickness.
