Case in brief
A patient presented with nausea, vomiting, tremors, and visual changes after an oral ingestion of levamisole, leading to bradycardia and pulseless electrical activity cardiac arrest. Despite treatment efforts, the patient succumbed. Post-mortem testing confirmed levamisole at a concentration of 19,000 ng/mL, establishing the cause of death as levamisole overdose.
Diagnostic / clinical pearl
Clinicians should be aware that levamisole can cause severe toxicity, including cardiovascular collapse, even in the absence of coingestants.
