    Moderate interaction

    Reviewed by the OmniRx Health clinical team•Last reviewed Jul 4, 2026

    Severity: Moderate

    Severity basis: drug interactions section (keywords: may increase). Combining Cyclosporine (Calcineurin inhibitor immunosuppressant) and Naproxen (Nonsteroidal anti-inflammatory drug (NSAID)) is classified as a moderate interaction.

    What to Do

    Use this combination with caution. Your prescriber may monitor you more closely or adjust doses.

    How This Interaction Works

    Interactions like this one can happen when two medicines have overlapping effects, or when one changes how the other is absorbed, broken down, or cleared from the body. Cyclosporine is a calcineurin inhibitor immunosuppressant and Naproxen is a nonsteroidal anti-inflammatory drug (nsaid); together they are documented as a moderate interaction. How much this matters depends on your dose, your other medications, and your overall health.

    If You Take Both Medications

    If you have been prescribed both Cyclosporine and Naproxen, do not start, stop, or change either medication on your own — some medicines are unsafe to stop suddenly. Tell your prescriber and pharmacist that you take both so they can decide whether the combination is right for you, adjust the dose, monitor you more closely, or suggest an alternative.
