title: Encainide overdose in an infant.
abstract: Ingestion of as little as a single tablet of encainide resulted in life-threatening ventricular arrhythmias in a child. Insertion of an intraosseous line permitted prompt delivery of medications and fluids. Prehospital care providers must be aware that apparently trivial amounts of some adult dosage forms can be toxic to small children.
