Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

ConditionStarting DoseMaintenance Dose
Mild-to-moderate pain (adults)250–500 mg orally every 12 hoursMax 1,250 mg/day for short-term; 1,000 mg/day for chronic use
Osteoarthritis or rheumatoid arthritis250–500 mg orally twice daily500–1,000 mg/day in divided doses
Acute gout flare750 mg orally once, then 250 mg every 8 hoursContinue until attack subsides (typically 5–7 days)

OTC self-care (adults)220 mg every 8–12 hoursMax 660 mg/24 hours; not more than 10 days without medical advice

Side Effects

Common side effects may include:

Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Naproxen shares the standard NSAID interaction profile, with longer plasma half-life (12–17 hours) than most other NSAIDs, prolonging both efficacy and the duration of interactions.

  • Anticoagulants (e.g., warfarin, DOACs) and antiplatelet agents: Significantly increase the risk of GI and other bleeding. Avoid combination when possible; use the shortest course and consider gastroprotection.
  • Low-dose aspirin (cardioprotective): Naproxen taken before aspirin may block the antiplatelet effect of aspirin by occupying COX-1. If both are needed, take aspirin at least 30 minutes before naproxen, or 8 hours after.
  • ACE inhibitors, ARBs, and diuretics: Naproxen can blunt antihypertensive effect and increase risk of acute kidney injury, particularly when all three classes are combined.
  • Lithium: Reduces renal lithium clearance, raising serum levels and the risk of toxicity. Monitor lithium concentrations closely.
  • Methotrexate: Can reduce methotrexate clearance and increase toxicity, especially at oncology-level doses. Use cautiously.
  • SSRIs / SNRIs: Combined use increases the risk of upper GI bleeding. Consider gastroprotection in higher-risk patients.
  • Cyclosporine: Concurrent use increases the risk of nephrotoxicity. Monitor renal function carefully.

Frequently Asked Questions

Naproxen sodium (the form in Aleve) is absorbed more quickly than the base form (Naprosyn), providing faster onset of pain relief — typically within 30 minutes. The two forms have equivalent total exposure once absorbed, just different absorption profiles. Naproxen 500 mg is roughly equivalent to naproxen sodium 550 mg.
Some observational evidence suggests that naproxen may have a more favorable cardiovascular safety profile than other NSAIDs at high doses, but this advantage is modest, and all NSAIDs carry a cardiovascular boxed warning. For patients with established cardiovascular disease, the lowest effective dose for the shortest duration remains the best approach regardless of NSAID choice.
OTC labeling recommends not exceeding 10 days for pain or 3 days for fever without consulting a healthcare provider. Longer-term use should be supervised by your doctor, with periodic monitoring of kidney function, blood pressure, and stomach symptoms. Older adults face higher risk of complications even at OTC doses.
Yes. Acetaminophen and naproxen work through different mechanisms and can safely be taken together for additional pain relief, often more effective than either alone for moderate pain. Stay within the recommended dose limits for each medication, and avoid combining naproxen with other NSAIDs.
Take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. Do not double up to make up for a missed dose — this can increase side effects without proportional benefit. For as-needed pain control, simply take the next dose when needed.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

  • Given my age, blood pressure, and kidney function, is naproxen a safe choice for me long-term?
  • How does naproxen interact with my other medications, particularly any blood thinners or blood pressure pills?
  • What stomach-protective measures should I be taking while on this NSAID?
  • Are there non-medication strategies that could reduce my need for daily NSAIDs?
  • When should I be reassessed for whether I still need this medication?
