Clemastine

Clemastine is used to prevent and relieve allergic conditions which cause itching and some allergic skin reactions.
The most common side effects are drowsiness and dry mouth.

About clemastine

Type of medicine	Antihistamine
Used for	Relief of allergic conditions
Also called	Tavegil
Available as	Tablets

Exposure to pollen, pet fur, house dust or an insect bite can cause the body to release a chemical called histamine. The release of histamine causes allergic symptoms that can include sneezing, watery eyes, a running or blocked nose and sometimes skin reactions such as itching, swelling and rashes. Antihistamines lessen the effects of histamine and help to relieve these symptoms.

Before taking clemastine

Before taking clemastine make sure your doctor or pharmacist knows:

If you are pregnant, trying for a baby or breast-feeding.
If you suffer from liver, kidney or prostate problems.
If you suffer from epilepsy, porphyria or glaucoma.

How to take clemastine

Take clemastine exactly as directed by your doctor.
