About Carbamazepine 200 mg Tablet

This medicine is used to control seizures in epilepsy, to relieve the sharp face pain of trigeminal neuralgia, and sometimes to steady mood in bipolar disorder. It can rarely cause serious skin reactions, especially in people of Asian ancestry with a certain gene, and it affects many other medicines. Do not stop it suddenly.

How to use
Take it exactly as your doctor prescribed, usually with or after food. Swallow the tablet with water. If you have a slow-release tablet, do not crush or chew it. Do not stop it suddenly.
How it works
It calms overactive nerve cells by blocking sodium channels, which reduces the spread of abnormal electrical signals in the brain and nerves.
