ALLEGRA ALLERGY (fexofenadine hydrochloride) is a non-sedating H1-receptor antagonist oral tablet approved for allergic rhinitis and chronic urticaria. It works by blocking histamine receptors to reduce allergy symptoms without crossing the blood-brain barrier, minimizing sedation. The drug is a selective peripheral antihistamine used as first-line therapy for mild-to-moderate allergic conditions.
