Abstract
We present the case of a 57-year-old Type2 diabetic man with chronic renal failure under hemodialysis, who injected himself with 1,200 units of regular insulin subcutaneously in a suicide attempt. He had been diagnosed with chronic hepatitis C and treated for depression. He was admitted to our hospital two hours after the overdose injection, because of severe hypoglycemia and unconsciousness. Despite continuous glucose injection, hypoglycemia persisted for twenty-four hours. He recovered completely without any complications.
