Olanzapine overdose in an 18-month-old child.

Olanzapine is an atypical antipsychotic medication that was approved for use in the United States in 1996. While it is a widely used medication in adults, there has been minimal investigation into its effect on children. We present the case of an 18-month-old boy who ingested 30-40 mg of olanzapine, which resulted in significant symptoms, including respiratory distress and mental status changes. Previously reported pediatric cases of olanzapine ingestion have described similar symptoms. Therefore, the pediatric population should be monitored closely when ingestions of olanzapine occur.
