Fexofenadine (commonly known by the brand name Allegra) is a second-generation antihistamine used to treat indoor and outdoor allergy symptoms like hay fever, sneezing, runny nose, and itchy eyes, as well as skin hives. It works by blocking histamine and is widely preferred because it rarely causes drowsiness.
