Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Sumatriptan is a selective 5-HT1B/1D receptor agonist, causing vasoconstriction of cranial blood vessels and inhibition of trigeminal nerve transmission. Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis.
Selective 5-HT1B/1D receptor agonist; causes vasoconstriction of cranial arteries and inhibits trigeminal nerve transmission.

Avoid use in elderly due to increased risk of cardiovascular events, gastrointestinal bleeding, and renal impairment; if necessary, use lowest effective dose for shortest duration.
Limited data in elderly. Start with the lowest effective dose (e.g., oral 25 mg, subcutaneous 3 mg, nasal spray 5 mg). Caution due to potential for cardiovascular risk, hypertension, and reduced hepatic/renal function. Avoid in patients with uncontrolled hypertension or ischemic heart disease.
Cardiovascular and gastrointestinal risks: NSAIDs increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use. NSAIDs also increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Sumatriptan is contraindicated in patients with history of coronary artery disease or risk factors. Do not use within 24 hours of another 5-HT1 agonist or ergotamine-containing medication.

No significant food interactions. Avoid alcohol during migraine attacks as it can worsen headaches. May be taken with or without food.
Sumatriptan: Limited data; no increased risk of major congenital malformations observed in cohort studies. Avoid use in third trimester due to potential uterine vasoconstriction and reduced placental perfusion. Naproxen: First trimester – potential increased risk of cardiac defects; second trimester – generally safe with caution; third trimester – contraindicated due to risk of premature ductus arteriosus closure, oligohydramnios, and fetal renal dysfunction.
FDA Pregnancy Category C. In first trimester, no increased risk of major congenital malformations from available data; however, animal studies show embryo lethality and increased malformations at high doses. Second and third trimester risks include potential for uterine hypertonus and fetal hypoxia during maternal use for migraine attacks; avoid during third trimester due to risk of premature uterine contractions.
Sumatriptan: Excreted in breast milk with estimated relative infant dose of 3.5% of maternal weight-adjusted dose; M/P ratio not well defined. Naproxen: Excreted in breast milk with M/P ratio approximately 0.01; relative infant dose <1% of maternal dose. Both considered compatible with breastfeeding with monitoring for infant adverse effects.
Sumatriptan is excreted into human breast milk with a relative infant dose of 3.5% of maternal weight-adjusted dose (M/P ratio approximately 0.6-4.3). Clinical studies show no adverse effects in breastfed infants; however, wait at least 12 hours after injection or 24 hours after oral dose to breastfeed to minimize exposure.
No specific dose adjustments recommended for sumatriptan in pregnancy; however, limited data suggest no significant pharmacokinetic changes. Naproxen: Clearance may increase in later pregnancy; dose adjustments not well studied. Avoid naproxen in third trimester.
No specific dose adjustments required for pregnancy based on pharmacokinetic changes; however, lower starting doses may be considered due to increased sensitivity to vascular effects. Avoid use in preeclampsia or uncontrolled hypertension.
Sumatriptan/naproxen sodium is contraindicated within 24 hours of another triptan or ergotamine. Naproxen dose is fixed; avoid additional NSAIDs to prevent GI bleeding or renal impairment. Use with caution in patients with cardiovascular risk factors. Onset of action is 10-30 minutes; advise against driving if dizziness occurs.
Sumatriptan is a 5-HT1B/1D receptor agonist used for acute migraine. It is available in oral, nasal, subcutaneous, and rectal formulations. Onset of action is fastest with subcutaneous injection (10-15 minutes). Avoid use within 24 hours of other triptans or ergot alkaloids. Contraindicated in patients with ischemic heart disease, cerebrovascular disease, uncontrolled hypertension, or hemiplegic/basilar migraine. Monitor for serotonin syndrome when combined with SSRIs/SNRIs.

"Naproxen and meloxicam are both nonsteroidal anti-inflammatory drugs (NSAIDs) that inhibit cyclooxygenase (COX) enzymes, leading to decreased synthesis of prostaglandins, prostacyclin, and thromboxanes. Concomitant use increases the risk of dose-dependent adverse effects, particularly gastrointestinal ulceration, bleeding, and perforation, as well as renal impairment, due to additive inhibition of protective prostaglandins in the gut and kidney. Clinically, this combination may result in acute kidney injury, anemia from occult gastrointestinal bleeding, or life-threatening perforation, especially in elderly patients or those with pre-existing renal disease or peptic ulcer history."
"Bevantolol, a beta-1 selective adrenergic receptor antagonist, reduces cardiac output and suppresses renin release, thereby lowering blood pressure. Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX) enzymes, leading to decreased synthesis of vasodilatory prostaglandins and enhanced sodium and water retention. The net effect is an attenuation of bevantolol's antihypertensive efficacy, potentially resulting in elevated blood pressure and reduced cardiovascular protection."
"Betaxolol, a beta-1 selective adrenergic receptor antagonist, may reduce the antihypertensive efficacy of naproxen, a nonsteroidal anti-inflammatory drug (NSAID). Naproxen inhibits cyclooxygenase (COX) enzymes, leading to decreased synthesis of vasodilatory prostaglandins (e.g., prostacyclin) in the renal and vascular endothelium. This can result in sodium and fluid retention, increased systemic vascular resistance, and blunting of the blood pressure-lowering effects of beta-blockers like betaxolol, potentially compromising hypertension control."
"Concurrent use of sumatriptan, a serotonin 5-HT1B/1D receptor agonist, and rasagiline, a selective monoamine oxidase B (MAO-B) inhibitor, can lead to serotonin syndrome due to excessive serotonergic activity in the central nervous system. Rasagiline inhibits the metabolism of serotonin, while sumatriptan indirectly increases serotonin release; their combination may result in life-threatening neuromuscular excitation, autonomic instability, and altered mental status. Symptoms may include hyperthermia, rigidity, myoclonus, and rapid fluctuations in vital signs, requiring immediate medical intervention."
"Sumatriptan, a 5-HT1B/1D receptor agonist used for migraine, and sulpiride, a dopamine D2 receptor antagonist with atypical antipsychotic properties, may exhibit additive or synergistic effects on the central nervous system. This combination can potentially increase the risk of serotonin syndrome (due to sumatriptan's serotonergic activity) and may also lead to enhanced extrapyramidal symptoms or neuroleptic malignant syndrome via combined dopaminergic antagonism. Clinical outcomes may include hyperthermia, rigidity, altered mental status, and autonomic instability."
"The combination of sumatriptan (a 5-HT1B/1D receptor agonist) and paroxetine (a selective serotonin reuptake inhibitor) increases the risk of serotonin syndrome, a potentially life-threatening condition characterized by neuromuscular excitation, autonomic instability, and altered mental status. This interaction is due to additive serotonergic effects, as both drugs enhance serotonin activity in the central nervous system. Clinical outcomes range from mild symptoms (tremor, hyperreflexia, diaphoresis) to severe manifestations (hyperthermia, rigidity, seizures) and require immediate medical attention."
