Carbamazepine can cause serious side effects, including:

1.

Carbamazepine may cause rare but serious rashes that may lead to death. These serious skin reactions are more likely to happen within the first four months of carbamazepine treatment but may occur at later times. These reactions can happen in anyone, but are more likely in people of Asian descent.

• hives
• sores in your mouth
• blistering or peeling of the skin

2.

Carbamazepine can also cause other types of allergic reactions or serious problems that may affect organs and other parts of your body such as your liver or blood cells. You may or may not have a rash when you get these types of reactions. Call your healthcare provider right away if you have any of these symptoms:

• swelling of your face, eyes, lips, or tongue

These symptoms may be the first signs of a serious reaction. A healthcare provider should examine you to decide if you should continue taking carbamazepine.

3.
