Fexofenadine is the active metabolite of terfenadine. It is a selective histamine H 1 receptor antagonist that does not cross the blood brain barrier; therefore, it is not associated with sedation or adverse cognitive effects. Unlike older antihistamines, fexofenadine does not have anticholinergic activity.here have been no comparative trials with fexofenadine and the intranasal nonsedating antihistamines (azelastine and levocabastine) in patients with seasonal allergic rhinitis. As with other oral nonsedating antihistamines, fexofenadine has little effect on nasal congestion.
Fexofenadine is an antihistamine. It is used to relieve the symptoms of hay fever (seasonal allergic rhinitis) and hives of the skin (chronic idiopathic urticaria) . Antihistamines work by preventing the effects of a substance called histamine, which is produced by the body.
