Background
- Bupropion is a norepinephrine/dopamine reuptake inhibitor used for depression, ADHD, and smoking cessation

- Develops within first 1-4hr for regular-release, up to 8hr for delayed release forms
- Hypotension and cardiogenic Shock
Differential Diagnosis
Evaluation
- CBC, CMP
- ECG to eval for QT prolongation
Management
- GI decontamination
- Consider whole-bowel irrigation for sustained-release formulations
- Seizure Treatment
- Benzos are 1st line
- Barbiturates are 2nd line
- Early vasopressor and ionotropic agents for hemodynamic instability (Bupropion depresses myocardial contractility)
- Intralipid for refractory cases
Disposition
- Consider discharge if asymptomatic after 8hr for regular-release ingestions
