serotonin syndrome
Pronunciation: ser-uh-TONE-in SIN-drohm
A potentially life-threatening condition caused by excessive serotonergic activity, often resulting from drug interactions or overdose.
Full Definition
Serotonin syndrome is a serious adverse drug reaction characterized by a triad of altered mental status, autonomic hyperactivity, and neuromuscular abnormalities. The condition typically results from the concurrent use of multiple serotonergic medications, such as SSRIs, SNRIs, MAOIs, or certain supplements like St. John's wort. Clinical manifestations can range from mild symptoms like tremor and diarrhea to severe complications including hyperthermia, seizures, and coma. In psychiatric research, serotonin syndrome represents a critical safety concern, particularly in studies involving multiple psychoactive medications or drug interaction evaluations. The condition requires immediate medical intervention and discontinuation of offending agents. Recognition of serotonin syndrome is essential for clinical investigators conducting studies with serotonergic compounds.
