How to take Zyban:

Swallow Zyban whole. Do not crush or chew them or the sustained activity of the drug will be destroyed and the chances of side effects occurring may be increased. Take as directed, usually twice daily for 7 to 12 weeks.

Do not take more or less medication than prescribed. Since Zyban can cause sleeplessness at first, it is best not to take near bedtime. It is advised to continue smoking for the first week after starting this drug, until it reaches higher levels in your blood. Do not smoke if using any nicotine products with this drug. Too much nicotine can cause serious side effects.

Zyban Cautions:

Before taking Zyban tell the prescribing 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 this drug. Tell your doctor if you are pregnant or plan to become pregnant before taking this drug. This drug 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.
