Contributor: Nick Tsipis, MD

Educational Pearls:

  • Arsenic is a heavy metal that binds to multiple cellular enzymes and inhibits aerobic metabolism
  • It is primarily absorbed through the skin, respiratory and GI tract.
  • The classic symptoms of heavy metal exposure are GI irritation (watery diarrhea, vomiting and abdominal pain) with multisystem organ failure.
  • Neuropathy can present insidiously
  • Initial work up includes EKG, and basic lab work (expect a delayed rise in liver function tests).
  • Acute arsenic ingestions can sometimes show up on imaging as it is radioapaque
  • Diagnosis is usually made with the history and evidence of multisystem organ failure.
  • Treatment should be coordinated with your local Poison Control or toxicologist and involves predominantly supportive care along with chelating agents succimer (oral) or dimercaprol (intramuscular)
