Quick Summary

Serotonin syndrome is a medical condition that occurs when there is too much serotonin in the brain and body, often due to certain medications. Serotonin is a neurotransmitter derived from the amino acid tryptophan that plays a role in mood, sleep, and sex drive.12

While lower serotonin levels are linked to conditions like anxiety and depression, excessive serotonin activity can lead to symptoms such as migraines and nausea. If left untreated, severe serotonin syndrome can be fatal. Milder cases are managed by discontinuing the offending medications until serotonin levels return to normal.21
