Bupropion (Zyban) has recently been launched in the UK as an aid to smoking cessation. As a result of the considerable publicity, there has been unprecedented demand for this new drug in primary care. Within a few weeks of its launch, four patients presented to our A&E department having taken bupropion as an intentional overdose. Three recovered with simple supportive measures; one one was critically ill and required admission to the intensive care unit. There are several case reports on bupropion overdose in the US but none so far in the UK.

Background: More than 1 million people in the United States meet the criteria for cocaine use disorder (CUD), and over 19,000 people died from cocaine-related overdoses in 2020, but there are currently no FDA-approved medications for the treatment of CUD. Bupropion is an antidepressant currently prescribed to treat depression and nicotine addiction that acts by inhibiting norepinephrine and dopamine transporters.
Methods: In this study, we tested the effect of several doses of systemic bupropion on cocaine self-administration in male and female Wistar rats.

: Bupropion, an atypical antidepressant and smoking cessation aid, is known for its potential to cause seizures, cardiotoxicity and neurotoxicity in overdose scenarios. However, overdoses may present variably, and muscular and renal complications, such as rhabdomyolysis and acute kidney injury (AKI), can emerge in unexpected ways. Previous reports have shown that severe overdoses can lead to a spectrum of complications, but the precise mechanisms linking bupropion overdose with rhabdomyolysis remain poorly understood.
