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. 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 immediately 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 immediately if you experience any of the symptoms listed above. Tell your doctor right away if you have any of these symptoms after stopping treatment.Who should not take bupropion HCl?
This medication is used in combination with a stop-smoking program (e.g., support group, counseling) to help you quit smoking. Bupropion can decrease your nicotine withdrawal symptoms (e.g., 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 chemicals (neurotransmitters) 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.
