Amoxicillin overdose in the pediatric emergency department: A descriptive study.

Objective: To describe the characteristics of pediatric patients treated in the  emergency department due to amoxicillin overdosing.
Method: A retrospective single-center observational study was conducted on  patients aged 0 to 16 years treated in a pediatric emergency department due  to amoxicillin overdosing between 2011 and 2021. Epidemiological and  anthropometric data was collected as well as information on the circumstances  of overdosing, clinical manifestations, emergency department management,  and discharge destination.
Results: The study comprised 15 patients, 66.6% of them male, with a median age of 3.8 years (interquartile range: 1.9). The most frequent cause  of overdosing was accidental ingestion (8/15; 53.3%). Amoxicillin was mainly ingested in liquid form, except for one case with autolytic attempt,  where it was ingested in the form of tablets. Eighty percent of subjects (12/15) received a single dose of the drug. The median time to presentation to  emergency department was 2.1 hours from ingestion (interquartile range: 2.7) and the median dose of amoxicillin was 219 mg/kg/dose (interquartile range:  148). All patients were asymptomatic, with a normal physical examination.  Blood tests were performed in 7 patients (46.6%) and urinary sediment  analysis in 2 (13.3%), all of them without alterations. Activated charcoal was  administered to 5 (33.3%), patients with a median time to administration of  one hour (interquartile range: 1.2). All patients were discharged to their  homes. Eleven cases (73.3%) required withdrawal of amoxicillin.
Conclusions: Amoxicillin overdosing in this study did not appear to result in  adverse effects, despite the fact that the recommended doses were  significantly exceeded.
