HIGH-DOSE LEVOTYROXIN RECEPTION IN CHILDREN: CASE REPORTS REVIEW OF THE LITERATURE AND DOSE-SYMPTOM-TREATMENT RELATION

Abstract

Levothyroxine (LT4) intoxication, which is rare in adults, is more common in children. In this study, we presented four cases who presented to the emergency department with excess LT4 intake. Only one case had prominent clinical symptoms such as headache, tremor, and convulsions. All the cases followed up ten days and cases did not develop any complication during this period. It is recommended to measure thyroid hormone levels for 10 days after acute LT4 intoxication. The cut-off of toxic dose is unclear. While symptoms may be seen after minimal overdose in adolescents, symptoms may not be seen at high doses in many cases. Symptoms may appear days or even months after taking the medication. The recommendations of guidelines depend on the quantity of LT4 that has been ingested. It is necessary to establish treatment protocols for LT4 intoxication.
