Side effects of bupropion in detail

Below you’ll find details on some of the side effects of bupropion oral tablet.

Risk of suicidal thoughts and behaviors in certain people

Bupropion has a boxed warning for the risk of suicidal thoughts and behaviors in certain people. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).

In studies involving bupropion oral tablet and other antidepressant medications, a small increase in the risk of suicidal thoughts and behaviors occurred. The increase was observed in adolescents and young adults up to age 24 years. This side effect may be serious.

It’s important to point out that:

  • depression (which bupropion is prescribed to treat) and other mental health conditions are the biggest risk factor for developing suicidal thoughts and behaviors; and
  • bupropion and other antidepressants did not increase this risk in adults ages 25 years and older in these studies; and
  • bupropion and other antidepressants lowered this risk in adults ages 65 years and older

This risk is most notable when beginning treatment with bupropion and whenever the dose is increased.

With suicidal thoughts and behaviors, you have thoughts of harming yourself. Symptoms may include expressing that you wish you weren’t alive. They may also include treating people as if you may not see them again. 

Ways to manage

If you experience symptoms or have concerns about suicidal thoughts and behaviors, tell your doctor right away. They can review possible treatments for your symptoms. They’ll also likely recommend stopping treatment with bupropion and reviewing treatments for depression with you.

If you feel comfortable doing so, it may be helpful to let a close family member or friend know you’re taking bupropion. They can help watch for changes in your behaviors, moods, or thinking while you’re taking the medication.

Suicide prevention

If you or someone you know is in crisis and considering suicide or self-harm, please seek support:

If you’re calling on behalf of someone else, stay with them until help arrives. You may remove weapons or substances that can cause harm if you can do so safely.

If you are not in the same household, stay on the phone with them until help arrives.

* Bupropion oral tablet has a boxed warning for this side effect. A boxed warning is the most serious warning from the FDA. To learn more, see the “Risk of suicidal thoughts and behaviors in certain people” section just above.
