    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. Aspirin is a antiplatelet / nsaid and Desvenlafaxine is a snri antidepressant; 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 Aspirin and Desvenlafaxine, 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.
