title: Fatal cardiovascular collapse following acute colchicine ingestion.
abstract: BACKGROUND
  A previously published prognostic rule predicts 100% survival after ingestion of cochicine doses less than 0.5 mg/kg and 100% mortality after ingestion of more than 0.8 mg/kg. This rule inaccurately predicted survival in a recent case.
  
  
  METHODS
  We present a case of fatal colchicine poisoning in an adult who ingested a maximum of 39.6 mg of colchicine (0.40 mg/kg). He subsequently developed hypotension which was refractory to fluid resuscitation and infusion of vasopressors. He died of cardiovascular collapse approximately 35 hours after ingestion.
  
  
  CONCLUSIONS
  Fatal outcomes are possible even with colchicine doses less than 0.5 mg/kg. Physicians caring for colchicine-poisoned patients must be prepared for the possibility of acute cardiovascular collapse and ventricular dysrhythmias regardless of the reported dose of colchicine.
