Abstract

It is the most frequently prescribed antipsychotic drug in children and adolescents worldwide. This drug has several adverse effects, however, palpebral ptosis is rarely reported with its usage. In the few published case reports, palpebral ptosis after the administration of risperidone was considered a presentation or an exacerbation of myasthenia gravis. The purpose of this case report is to present a 5-year-old boy who developed a palpebral ptosis after the initiation of 0.15 ml of risperidone for a sleep disorder (night terrors).
