Fatal nifedipine ingestions in children.

Nifedipine is a prototypical dihydropyridine calcium channel "blocker" that can cause hypotension and cardiac conduction abnormalities. When compared to other calcium channel antagonists, overdoses have been reported to be relatively benign with treatment consisting mainly of supportive care. We report two pediatric cases of death secondary to accidental ingestion of long acting nifedipine (Adalat). Both cases did not respond to aggressive supportive care that included calcium, atropine, epinephrine, glucagon, sodium bicarbonate, and transthoracic pacing.
