Can Naproxen (Naxdom) Be Used for 3 Days for Migraine?

Yes, naproxen can be safely used for up to 3 consecutive days for migraine treatment, but this should be limited to no more than twice weekly overall to prevent medication-overuse headache. 1, 2

Dosing Strategy for Acute Migraine

• Initial dose: 500-825 mg of naproxen sodium at migraine onset, ideally when pain is still mild 1, 3
• Repeat dosing: Can be repeated every 2-6 hours as needed, with a maximum of 1.5 g per day 1
• Duration: While 3 consecutive days is acceptable for a single prolonged attack, the critical limitation is total frequency per week, not consecutive days 2

Critical Frequency Limitation to Prevent Medication-Overuse Headache

• Limit acute migraine medication use to no more than 2 days per week (not 2 attacks, but 2 calendar days) to avoid medication-overuse headache 2
• Using naproxen for 3 consecutive days for a single severe or prolonged attack is reasonable, but this should not become a weekly pattern 1, 2
• If you find yourself needing acute treatment more than twice weekly, preventive therapy is indicated rather than increasing acute medication frequency 4, 2

Efficacy Considerations

• Naproxen 500-825 mg provides pain-free response in only 17% of patients at 2 hours (NNT = 11), which is modest compared to triptans 5
• Headache relief (reduction but not complete resolution) occurs in 45% at 2 hours (NNT = 6.0) 5
• Naproxen works better for common migraine than classical migraine 6
• Onset of pain relief typically begins within 1 hour 3

Enhancing Efficacy with Adjunctive Therapy

• Add an antiemetic (metoclopramide 10 mg or prochlorperazine 25 mg) 20-30 minutes before naproxen to treat nausea and provide synergistic analgesia 1, 7
• This combination significantly improves outcomes compared to naproxen alone 1
• The antiemetic helps even without vomiting, as nausea itself is disabling 2

When to Escalate Beyond Naproxen

• If naproxen fails after 2-3 migraine episodes, switch to a triptan (sumatriptan, rizatriptan, or others) for moderate-to-severe attacks 1, 2
• For severe attacks unresponsive to NSAIDs, consider dihydroergotamine (DHE) 1, 7
• If attacks occur more than twice weekly despite optimal acute treatment, initiate preventive therapy (propranolol, topiramate, or candesartan as first-line options) 4

Common Pitfalls to Avoid

• Do not exceed twice-weekly use even if individual attacks last multiple days, as this creates a vicious cycle leading to daily headaches 2
• Do not delay treatment—naproxen is most effective when taken early in the attack while pain is still mild 2, 3
• Do not use naproxen in patients with renal impairment (creatinine clearance <30 mL/min), aspirin/NSAID-induced asthma, or active GI bleeding 1, 3
• Monitor total daily acetaminophen if using combination products to avoid exceeding 4 g/day 2

Safety Profile

• Adverse events with naproxen 500-825 mg are mostly mild to moderate (dizziness, rash, GI upset, constipation) and rarely lead to withdrawal 1
• The 500 mg dose has a more favorable side effect profile than 825 mg 5
• Use the lowest effective dose for the shortest duration consistent with treatment goals 3
