What is bupropion?
The Zyban brand of bupropion is used to help people stop smoking by reducing cravings and other withdrawal effects.
Bupropion may also be used for purposes not listed in this medication guide.
How should I take bupropion?
Take bupropion exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Too much of this medicine can increase your risk of a seizure.
Do not crush, chew, or break an extended-release tablet. Swallow the tablet whole.
You should not change your dose or stop using bupropion suddenly unless you have a seizure while taking this medicine. Stopping suddenly can cause unpleasant withdrawal symptoms.
Ask your doctor how to safely stop using bupropion.
If you take Zyban to help you stop smoking, you may continue to smoke for about 1 week after you start the medicine. Set a date to quit smoking during the second week of treatment. Talk to your doctor if you are having trouble quitting after you have used Zyban for at least 7 to 12 weeks.
Your doctor may prescribe a nicotine replacement product (such as patches or gum) to help you stop smoking. Start using the nicotine replacement product on the same day you stop (quit) smoking or using tobacco products.
