Table of contents:

Clarinex Syrup is a prescription medication used to treat allergy symptoms such as itching, sneezing, runny nose, and watery eyes. It contains the active ingredient desloratadine, which is an antihistamine.

Desloratadine works by reducing the effects of histamine, a natural substance produced by the body in response to an allergy, such as runny nose, watery eyes, itchiness, and sneezing. By blocking the action of histamine, Clarinex helps to relieve allergy symptoms.
