Like all medicines, Zyban may cause side effects. Do not rely on this summary alone for information about side effects. Your doctor can discuss with you a more complete list of side effects that may be relevant to you. Hypertension (high blood pressure), in some cases severe, has been reported when taking Zyban alone and in combination with nicotine replacement therapy (for example a nicotine patch). The most common side effects include dry mouth and difficulty sleeping. These side effects are generally mild and often disappear after a few weeks. If you have difficulty sleeping, avoid taking your medicine too close to bedtime. The most common side effects that stopped taking Zyban during clinical studies were shakiness and skin rash. Stop taking Zyban and contact your doctor or health care professional if you have signs of an allergic reaction such as a rash, hives, or difficulty in breathing. It is not possible to predict whether a mild rash will develop into a more serious reaction. Therefore, if you experience a skin rash, hives, fever, swollen lymph glands, painful sores in the mouth or around the eyes, or swelling of lips or tongue, tell a doctor immediately, since these symptoms may be the first signs of a serious reaction. Discuss any other troublesome side effects with your doctor.
