Accumulating human registry data have not demonstrated a clear increase in major birth defects, but data are still limited. Many neurologists consider sumatriptan among the more reasonable options when triptan therapy is clearly needed during pregnancy, after non-drug measures and acetaminophen have been tried.

Drug Interactions
Sumatriptan activates 5-HT1B/1D receptors and is partly metabolized by monoamine oxidase A. The most important interactions involve serotonergic, vasoconstrictive, or MAO-related effects.
- MAO-A inhibitors (e.g., phenelzine, tranylcypromine, linezolid): Greatly increase sumatriptan exposure and risk of hypertensive or serotonin reactions. Sumatriptan is contraindicated within 14 days of MAO inhibitor use.
- Ergot derivatives (e.g., ergotamine, dihydroergotamine, methysergide): Additive coronary and peripheral vasoconstriction can cause prolonged ischemia. Do not use within 24 hours of each other.
- Other triptans: Combining triptans within 24 hours may produce excessive vasoconstriction. Use one triptan at a time per attack.
- SSRIs and SNRIs (e.g., sertraline, fluoxetine, venlafaxine, duloxetine): Theoretical risk of serotonin syndrome — confusion, autonomic instability, neuromuscular signs. The risk in clinical practice appears low, and the FDA has clarified that combination is generally acceptable with patient counseling and vigilance for symptoms.
- Vasoconstrictor decongestants and other ergotamine-class agents: Additive blood pressure elevation. Use cautiously, particularly in patients with hypertension.
