Sertraline-Induced Rhabdomyolysis, Trismus, and Cardiac Arrest in a Child.

Selective serotonin reuptake inhibitors are a commonly used and often effective class of medications in the treatment of mood disorders such as anxiety and depression. Sertraline (1S,4S-N-methyl-4-[3,4-dichlorophenyl]-1,2,3,4-tetrahydro-1-naphthylamine [Zoloft; Pfizer, New York City, NY]) is a frequently used selective serotonin reuptake inhibitor that has shown efficacy in children, adolescents, and adults. We report the case of a 13-year-old boy with sertraline-induced rhabdomyolysis and renal failure, trismus, and cardiopulmonary arrest. Pharmacogenetic testing later revealed our patient had serotonin transporter polymorphisms and enzymatic alterations that put him at risk for increased levels of sertraline and greater likelihood for untoward side effects.
