About Telfast 120mg Tablets

Telfast 120mg Tablets contain fexofenadine hydrochloride, a fast-acting, non-drowsy antihistamine used to relieve the symptoms of hay fever (seasonal allergic rhinitis).

It provides effective 24-hour relief from sneezing, runny or blocked nose, itchy nose, and itchy, red or watery eyes. Each tablet works by blocking histamine — a natural chemical released during allergic reactions — to help you feel clear and comfortable all day.

Telfast 120mg is suitable for adults and adolescents aged 12 years and over. It begins to work within 1 hour of taking and does not usually cause drowsiness, making it ideal for daytime allergy relief.
