A 22-day-old male neonate was referred to our emergency department from a community hospital after realization that an acute acetaminophen overdose had occurred, following routine circumcision.

The patient had been born at 40 weeks’ gestation after an uneventful delivery to a gravida 1 mother. The pregnancy had been complicated by pregnancy-induced hypertension, treated with labetalol. Prior to the overdose, the baby had been well.
