Clarinex

The active ingredient in Clarinex is desloratadine, which is an antihistamine. It inhibits histamine, a natural substance that can cause allergic symptoms such as itchy eyes, runny nose, sneezing, and hives. Clarinex treats perennial and seasonal allergic rhinitis by inhibiting histamine production.
