Does Lovastatin Interact With Spironolactone?
Caution should also be exercised if an HMG-CoA reductase inhibitor or other agent used to lower cholesterol levels is administered to patients also receiving other drugs (e.g., spironolactone, cimetidine) that may decrease the levels or activity of endogenous steroid hormones.
Severity: Moderate
Severity basis: drug interactions section (keywords: caution, may decrease). Combining Lovastatin (HMG-CoA reductase inhibitor (statin)) and Spironolactone (Potassium-sparing diuretic) 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. Lovastatin is a hmg-coa reductase inhibitor (statin) and Spironolactone is a potassium-sparing diuretic; 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 Lovastatin and Spironolactone, 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.
