Massive ingestion of sustained-release verapamil with a concretion and bowel infarction

Gastric concretions secondary to a drug overdose are uncommon but potentially fatal if not recognized and treated. They may continue to release drug into the stomach for hours or days after the ingestion, complicating diagnosis and treatment. We describe the case of a man with the previously unreported association of bowel infarction with a verapamil ingestion and concretion. This case illustrates the need for a heightened awareness of this potential complication.
