Severity basis: drug interactions section. Combining Fluconazole (Azole antifungal) and Simvastatin (HMG-CoA reductase inhibitor (statin)) is classified as a minor interaction.

What to Do

This is generally a minor interaction, but review it with your pharmacist to be sure it is safe for you.

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. Fluconazole is a azole antifungal and Simvastatin is a hmg-coa reductase inhibitor (statin); together they are documented as a minor 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 Fluconazole and Simvastatin, 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.
