Rhabdomyolysis After Risperidone Overdose in a Patient With Schizophrenia: A Case Report.

A 50-year-old woman with schizophrenia overdosed on risperidone, lormetazepam, and lorazepam and subsequently developed rhabdomyolysis, with elevated creatine kinase (CK) and myoglobin levels. Intravenous treatment stabilized her condition. Risperidone was restarted at a regular dose, and rhabdomyolysis did not recur. She was discharged after 29 days, and she continued outpatient care without further complications. There have been no reports of rhabdomyolysis caused by overdosing on risperidone alone. This case is important for understanding the risk profile of this drug.
