title: Management of a child with acute thyroxine ingestion.
abstract: We report a case of thyroxine overdose in a child. Despite extremely high thyroxine (T4RIA) levels on admission, the patient's only symptoms were mild hypertension and tachycardia. Both symptoms responded to propranolol, with a drop in pulse rate and a decrease in blood pressure to normal levels. After four days of cardiac monitoring, the patient was released and received propranolol for five additional days as an outpatient.
