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.
