Causes

Serotonin syndrome is caused by drugs that raise your serotonin levels. In most cases, it happens when you take two drugs that should not be used together. It can also happen when you take a new dosage of a drug. This syndrome can be triggered by certain pain relievers, antidepressants, and other drugs. It has been linked to some dietary supplements. And, it can be caused by certain illegal drugs.

Treatment

Treatment depends on your needs. You may need to stop taking a certain drug. You may need other medicines to help get your serotonin levels under control. If your symptoms are severe, you'll need treatment in a hospital. Your healthcare provider can create a plan that's right for you.
