What medical condition makes combining certain antidepressants and migraine drugs risky?

Answer

Serotonin syndrome

Combining certain classes of medications, such as specific antidepressants with particular migraine treatments, can trigger a potentially fatal condition known as serotonin syndrome. This occurs because the pharmacological interaction leads to an unsafe, excessive accumulation of serotonin in the body. Because the physiological outcome is potentially life-threatening, this specific combination of drugs is often viewed as a contraindication—either relative or absolute depending on the dosages and agents involved—requiring extreme vigilance or avoidance to prevent a systemic toxicity that can rapidly become a medical emergency.
