Medication Summary

The treatment of acute toxicity from arsenic consists primarily of maintaining hydration and electrolyte balance. The use of chelating agents hastens the removal of arsenic from the system. Management of arsine toxicity generally addresses the acute hepatorenal complications. The use of chelating agents in these cases is debatable.
