Wellbutrin (bupropion) is an antidepressant medication. Taking a very high dose of Wellbutrin alone or in combination with other drugs can have toxic effects.
The standard dose of Wellbutrin is 150‒300 mg daily for adults. Taking a higher dose of Wellbutrin than prescribed, or misusing it, can risk negative side effects, including overdose.
Determining The Lethal Dose Of Wellbutrin
Wellbutrin is a non-addictive drug that is rarely fatal on its own. Survival has been reported following the ingestion of as much as 13.5 grams—or 45 times the maximum daily dose.
Overdose and seizures can occur after taking a higher-than-prescribed dosage of Wellbutrin. One case report described a fatal Wellbutrin overdose after a man ingested 23,000 mg of Wellbutrin.
Risk Factors For Wellbutrin Overdose
Wellbutrin overdose is uncommon, but it can occur. This may be a sign of drug abuse, stimulant drug addiction, or suicidal ideation.
Potential risk factors for Wellbutrin overdose include:
- history of substance abuse
- having a mental health disorder
- polysubstance abuse (abuse of multiple drugs)
- history of stimulant addiction
- impaired kidney or liver function
