Table of contents:

Tavist is an oral medication used to treat symptoms such as itching, runny nose, watery eyes, and sneezing caused by allergies. Prescription strength clemastine is also used to relieve the itching and swelling of hives. Clemastine helps control symptoms of allergies and colds but does not treat the cause of these symptoms or speed recovery.

The active ingredient in Tavist is called Clemastine. Clemastine is in a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. By blocking another natural substance made by your body (acetylcholine), it helps dry up some body fluids to relieve symptoms such as watery eyes and runny nose.

Use and Dosage

Tavist comes as a tablet medication that should be taken by mouth, with or without food, and according to the directions on the label or as directed by your doctor. If stomach upset occurs, Tavist can be taken with food or milk.
