What does it do?

Fexofenadine hydrochloride is a second-generation antihistamine that is used to inhibit allergic reactions. It is primarily included in medications to alleviate allergy symptoms such as rhinitis or urticaria.

This ingredient binds to histamine receptors in the body, blocking the action of histamine. As a result, allergy symptoms such as sneezing, itching, and runny nose are reduced.
