Bupropion is an antidepressant used to treat a variety of conditions, including depression, other mental/mood disorders, and smoking cessation. Antidepressants can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience new or worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. It is very important to talk with the doctor about the risks and benefits of antidepressant medication, even if treatment is not for a mental/mood condition.

Tell the doctor right away if you notice new or worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.

If you are using bupropion to quit smoking, stop taking bupropion and contact your doctor right away if you experience any of the symptoms listed above. Tell your doctor right away if you have any of these symptoms after stopping treatment.

This medication is used in combination with a stop-smoking program (such as a support group, counseling) to help you quit smoking. Bupropion can decrease your nicotine withdrawal symptoms (such as irritability, anxiety, restlessness) and your urge to smoke. Quitting smoking decreases your risk of heart and lung disease, as well as cancer.

This medication belongs to a class of medications known as antidepressants. It is not known exactly how bupropion works to reduce smoking urges. It may work by restoring the balance of certain natural substances (dopamine, norepinephrine) in the brain.

Discuss the risks and benefits of this medication, as well as other ways to quit smoking (such as nicotine replacement treatment), with your doctor.

Do not take more or less medication or take it more often than prescribed. Taking more than the recommended dose of bupropion may increase your risk of having a seizure.

It is recommended that you do not try to quit smoking until you have been taking bupropion for 1 week so that the drug can reach a high enough level in your blood. Set a date for quitting, and stop smoking sometime in the second week of taking the drug.

If necessary, this medication may be combined with nicotine patches or gum to help you quit smoking. Ask your doctor for more information. The combination of nicotine and this medication may increase your blood pressure. Your doctor may need to monitor your blood pressure closely.
