Acute hemolysis following iodine tincture ingestion

Abstract

Iodine tincture poisoning is uncommon regardless of its widespread use as an antiseptic in daily practice. Previously reported effects of iodine-containing antiseptic poisoning included topical irritation, corrosive effects, allergic response, and hepatic or renal injury, which mainly resulted from complications of topical use during surgical procedures. We herein reported an unusual case of severe hemolysis and acute renal failure following intentional ingestion of iodine tincture containing 60 mg/ml iodine and 40 mg/ml potassium iodide in 70% v/v ethanol. The patient completely recovered 8 weeks later after receiving supportive treatment, plasma exchange, and temporary hemodialysis.
