Serotonin Syndrome
Medically reviewed by Drugs.com. Last updated on Jun 5, 2024.
Serotonin syndrome is a drug reaction that is caused by high levels of serotonin in your body. A severe reaction can be life-threatening. Drugs that affect serotonin levels, interactions between 2 or more drugs, and drug overdoses increase your risk. Even when used as directed, prescription drugs to treat depression, seizures, migraines, pain, vomiting, and Parkinson disease can lead to serotonin syndrome. St John's wort, cocaine, ecstasy, and cough syrup that contains dextromethorphan may also cause it.
