We present the case of a 25-year-old woman who, although normotensive on presentation, had a severe hypotensive episode more than 12 h after initial ingestion of sustained release verapamil. Management of asymptomatic patients who have overdosed on a sustained release preparation of a calcium channel blocker is discussed.
