title: Recognizing serotonin toxicity in the pediatric emergency department.
abstract: The use of selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors in treating depression, mood disorders, and behavioral disorders has escalated dramatically in the last 20 years, resulting in increased risk and clinical presentation of serotonin toxicity. Health care providers must also be aware of other medications and substances with proserotonergic activity that can cause serotonin toxicity when used in combination with these medications. There are many adverse effects of selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors, although their toxicity profile compared to older antidepressants seems to be safer. Serotonin syndrome is described as a clinical triad of mental status changes, autonomic hyperactivity, and neuromuscular abnormalities. It encompasses a spectrum of clinical findings ranging from a few nonspecific symptoms to significant clinical toxicity that can result in death. The objectives of this article are to review specific serotonergic medications including their adverse effects and toxicity in overdose, to describe other medications/substances that have proserotonergic effects, which could result in serotonin excess in combination with traditional serotonergic agents, and to define the criteria for serotonin syndrome/toxicity and its treatment.
