Non-Drowsy Antihistamine for Hayfever & Allergic Reactions
Fexofenadine is a prescription-only antihistamine used to treat seasonal hayfever (allergic rhinitis) and chronic urticaria (hives). It helps relieve sneezing, itchy or watery eyes, runny nose, and skin irritation — all without causing drowsiness.
It’s the generic form of Telfast, offering the same active ingredient at a lower cost.
