Bupropion (Zyban) overdose can cause serious neurological and cardiac issues, including seizures and arrhythmias. Healthcare providers should consider these risks when prescribing this smoking cessation aid.

Area of Science:

  • Pharmacology
  • Toxicology
  • Clinical Medicine

Background:

  • Bupropion hydrochloride, formulated as Zyban, is a smoking cessation aid.
  • Bupropion is a monocyclic antidepressant structurally related to amphetamine.

Observation:

  • 12 overdose cases of Zyban reported in Ireland within 6 months.
  • 8 patients exhibited toxicity symptoms: tachycardia, drowsiness, hallucinations, and convulsions.
  • Two patients experienced severe cardiac arrhythmias, one requiring resuscitation from cardiac arrest.

Findings:

  • Bupropion overdose can lead to significant neurological toxicity, including seizures.
  • Cardiovascular toxicity, such as tachycardia and arrhythmias, is a notable risk.
  • A severe case involved a 31-year-old female requiring ICU admission for 13.5g bupropion ingestion.
