Side Effects - Zyban is generally well tolerated. Dry mouth, headache, increased sweating, constipation, anxiety and fatigue may occur. If these effects persist or worsen, notify your doctor.
Precautions - Before taking bupropion tell your doctor if you have a history of seizures, head injury, brain tumor; heart, liver or kidney disease, an eating disorder or any mental conditions, diabetes or if you have any allergies. Limit or avoid consumption of alcoholic beverages; alcohol can increase your risk of seizures. Chronic alcohol users who suddenly stop the intake of alcohol while taking bupropion may increase the risk of having seizures. Suddenly stopping certain tranquilizers (e.g., diazepam, chlordiazepoxide) is not recommended because doing so may increase the risk of having seizures. Elderly patients may be more sensitive to the effects of Zyban. Tell your doctor if you are pregnant or plan to become pregnant before taking this prescription medicine to help you quit smoking. Zyban is excreted into breast milk. Because of the potential risk to the infant, breast-feeding while using Zyban is not recommended. Consult your doctor before breast-feeding.

Excess caffeine intake can increase the chance of seizures with Zyban. Check all nonprescription/prescription drug labels for caffeine. Consult doctor or pharmacist. A certain product used to help quit smoking contains bupropion. Do not take that product while using Zyban.
