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 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 or if you have any of these symptoms after stopping treatment.

This medication is used to treat depression. It can improve your mood and feelings of well-being. It may work by restoring the balance of certain natural chemicals (neurotransmitters) in the brain.

This medication must be swallowed whole. Do not crush, chew or break the tablets. Doing so will destroy the slow release of the drug and increase your risk of side effects, including seizures.

Since this drug may cause sleeplessness at first, it is best not to take it near bedtime. Your dose may be slowly increased to limit side effects such as sleeplessness, and to decrease the risk of seizures.

Do not take more or less medication than prescribed. Taking more than the recommended dose of bupropion will increase your risk of having a seizure. There are 2 forms of extended release bupropion (bupropion hydrochloride and bupropion hydrobromide). The usual maximum dose is 450 milligrams per day of bupropion hydrochloride or 522 milligrams of bupropion hydrobromide. The maximum dose depends on your medical condition and response to treatment. Ask your pharmacist for more details or if you have any questions.
