By Mayo Clinic staffTaking more than one serotonin-related medication may increase your risk of serotonin syndrome. This can be especially true if you're taking a serotonin reuptake inhibitor or a serotonin and norepinephrine reuptake inhibitor. Talk to your doctor about possible risks. Don't stop taking any such medications on your own. If your doctor prescribes a new medication, make sure he or she knows about all the other medications you're taking — especially if you receive prescriptions from more than one doctor.
If you and your doctor decide the benefits of combining certain serotonin-level-affecting drugs outweigh the risks, be alert to the possibility of serotonin syndrome.
