Serotonin syndrome

Serotonin syndrome is any of a group of symptoms which may be an indication of any number of potentially life-threatening drug interactions that may occur following therapeutic drug use, combination, overdose of particular drugs, or the recreational use of certain drugs. Serotonin syndrome is not an idiopathic drug reaction; it is a predictable consequence of excess serotonin on the CNS and/or peripheral nervous system. For this reason, some experts strongly prefer the terms serotonin toxicity or serotonin toxidrome which more accurately reflect that it is a form of poisoning.
