The U.S.Food and Drug Administration has issued a public health advisory about potential risks of taking certain migraine medications - triptans - together with certain antidepressants. The advisory states, “A life-threatening condition called serotonin syndrome may occur when triptans are used together with a SSRI or a SNRI.”

Serotonin syndrome occurs when the body has too much of serotonin, a chemical found in the nervous system. Serotonin syndrome may be more likely to occur when starting or increasing the dose of a triptan, SSRI or SNRI. Symptoms of serotonin syndrome may include:

• restlessness
• hallucinations
• loss of coordination
• fast heart beat
• rapid changes in blood pressure
• increased body temperature
• overactive reflexes
• nausea
• vomiting
• diarrhea
