Neuroleptic Malignant Syndrome Due to Risperidone Overdose in a Child: A Case Report

Neuroleptic malignant syndrome due to risperidone overdose in a child: a case report Neuroleptic malignant syndrome is a rare, but potentially fatal idiosyncratic reaction to antipsychotic drugs that manifests itself consistently with hyperthermia, muscle rigidity, akinesia, altered mental state, autonomic instability, high creatine phosphokinase levels, and leukocytosis. We report here a case of risperidone-induced neuroleptic malignant syndrome in a 2.5-year-old boy who was given by mistake 2.5 mg risperidone instead of 0.25mg, as it is the youngest case reported in the literature.
