Benadryl 10mg One a Day – 14 Tablets

Description

Benadryl 10mg One a Day – 14 Tablets

Benadryl Allergy One a Day tablets contain cetirizine hydrochloride, a non-drowsy antihistamine used to relieve the symptoms of hay fever and other allergies, such as reactions to pet hair, house dust mites, and mould.

⸻

How It Works

Cetirizine hydrochloride works by blocking histamine receptors in the body. Histamine is a natural chemical released during an allergic reaction, and it is responsible for symptoms such as sneezing, itching, a runny nose, and watery eyes. By blocking histamine, cetirizine helps to reduce or prevent these symptoms with just one tablet a day.
