Serotonin syndrome is an "adverse drug interaction characterized by altered mental status, autonomic dysfunction, and neuromuscular abnormalities. It is most frequently caused by use of both serotonin reuptake inhibitors and monoamine oxidase inhibitors, leading to excess serotonin availability in the CNS at the serotonin 1A receptor."[1][2]
Cause/etiology
The serotonin syndrome may be caused by many drugs including antidepressants. Coadministration of drugs that inhibit the cytochrome P-450 CYP2D6 and CYP3A4 metabolism of antidepressants may increase the risk.[2]
Notable cases
The death of Libby Zion was due to serotonin syndrome caused by a combination of meperidine and phenelzine.[2] This case had a profound impact on graduate medical education and residency work hour limitations.[3]
