Bupropion is an antidepressant used for smoking cessation and to treat a variety of conditions, including depression and other mental/mood disorders. Antidepressants can help prevent suicidal thoughts/attempts and provide other important benefits. However, 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. Therefore, 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 and experience any of these symptoms, stop taking it and contact your doctor right away. Also, tell your doctor right away if you have any of these symptoms after stopping treatment with bupropion.Who should not take Zyban?
