serotonin syndrome
A potentially life-threatening condition caused by excessive serotonergic activity, typically resulting from medication interactions.
Full Definition
Serotonin syndrome is a drug-induced condition characterized by altered mental status, neuromuscular abnormalities, and autonomic hyperactivity resulting from excessive central and peripheral serotonergic activity. The syndrome most commonly occurs with combinations of serotonergic medications such as SSRIs, SNRIs, MAOIs, and certain illicit drugs. Clinical presentation ranges from mild symptoms to severe, life-threatening complications including hyperthermia, seizures, and cardiovascular collapse. The Hunter Criteria provide standardized diagnostic guidelines for clinical assessment.
Usage
Usage note: Distinguish clearly from neuroleptic malignant syndrome in differential diagnosis documentation.
