Bupropion overdose can result in severe neurological and cardiovascular toxicity. We describe a 16-year-old girl who ingested 4.2 g of extended-release bupropion (90.3 mg/kg), presenting with seizures and out-of-hospital cardiac arrest. After 21 min of cardiopulmonary resuscitation, she was resuscitated and admitted with profound metabolic acidosis and electrocardiographic abnormalities. Serum testing confirmed markedly elevated bupropion levels. During hospitalization, she developed delayed rhabdomyolysis, hypoxic encephalopathy, and persistent neurological sequelae, including Parkinsonism and cognitive deficits. Supportive care led to gradual recovery, with normalization of cardiac conduction and drug clearance by day 20, though residual deficits remained at discharge after seven weeks. This case highlights the life-threatening complications of bupropion toxicity, the delayed risk of seizures, and the need for vigilance for secondary complications such as rhabdomyolysis.
