This case report describes a nearly fatal case of amlodipine poisoning in an 11-month old infant. The infant received 6 doses of 15mg of amlodipine which was mistakenly dispensed instead of amoxicillin. Within hours, the infant developed vomiting, lethargy, bradycardia, respiratory distress, and hypotension. Laboratory tests showed hyperglycemia, electrolyte abnormalities, and elevated liver enzymes. The infant was treated with insulin, calcium gluconate, ionotropes, and peritoneal dialysis. The infant's condition gradually improved and was discharged after 10 days. The authors conclude that hyperinsulinemia therapy is beneficial in treating calcium channel blocker toxicity and
