Overview
Serotonin syndrome is a serious drug reaction. It is caused by medications that build up high levels of serotonin in the body.
Symptoms
Serotonin syndrome symptoms usually occur within several hours of taking a new drug or increasing the dose of a drug you're already taking.
Causes
Excessive accumulation of serotonin in the body creates the symptoms of serotonin syndrome.
Risk factors
Some people are more likely to be affected by the drugs and supplements that cause serotonin syndrome than are others, but the condition can occur in anyone.
Complications
Serotonin syndrome generally doesn't cause any problems once serotonin levels are back to their original levels.
Prevention
Taking more than one serotonin-related medication or increasing your dose of a serotonin-related medication increases your risk of serotonin syndrome. Know what medications you take and share a complete list of your medications with your doctor or pharmacist.
Diagnosis
No single test can confirm a serotonin syndrome diagnosis. Your doctor will diagnose the condition by ruling out other possibilities.
