While taking

Clemastine is used to relieve hay fever and allergy symptoms, including sneezing; runny nose; and red, itchy, tearing eyes. 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. 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.

Clemastine comes as a tablet and a liquid to take by mouth. It is usually taken two or three times a day. Follow the directions on your prescription label or package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take clemastine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or directed by the label.

If you are taking the liquid, do not use a household spoon to measure your dose. Use the measuring spoon or cup that came with the medication or use a spoon made especially for measuring medication.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
