Serotonin Syndrome in a Pediatric Patient After Vilazodone Ingestion.

Serotonin syndrome (SS) is a serious toxicity that manifests with symptoms such as tremor, hyperthermia, agitation, and altered mental status that may lead to seizures, coma, or death. Selective serotonin reuptake inhibitors may precipitate SS, particularly in combination with other drugs that possess serotonergic activity. We present a case of SS in a 14-month-old after an ingestion of the selective serotonin reuptake inhibitor vilazodone.
