Lovastatin and Verapamil Interaction

Drug interaction information between Lovastatin and Verapamil.

Lovastatin and Verapamil have a documented moderate interaction in FDA labeling.

FDA drug labeling documents a moderate-severity interaction between Lovastatin and Verapamil. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.

Drug A

Lovastatin

HMG-CoA Reductase Inhibitor (Statin)

Drug B

Verapamil

Calcium Channel Blocker

How They Interact

Verapamil slows down the process of removing lovastatin from your body. This can cause lovastatin to reach high levels that increase the risk of muscle injury.

What To Do

Your doctor may need to limit your dose of lovastatin while you are on this medication. Tell your doctor immediately if you have unexplained muscle pain or weakness.

FDA Label Information

Danazol, Diltiazem, Dronedarone or Verapamil The risk of myopathy/rhabdomyolysis is increased by concomitant administration of danazol, diltiazem, dronedarone or verapamil particularly with higher doses of lovastatin (see WARNINGS , Myopathy/Rhabdomyolysis ; CLINICAL PHARMACOLOGY , Pharmacokinetics ).

Frequently Asked Questions

Can I take Lovastatin and Verapamil together?

This is a moderate interaction. Your doctor may need to limit your dose of lovastatin while you are on this medication. Tell your doctor immediately if you have unexplained muscle pain or weakness.

How serious is the interaction between Lovastatin and Verapamil?

This interaction is classified as "moderate" severity by the FDA. Moderate interactions may worsen your condition or change how your medications work.

Why do Lovastatin and Verapamil interact?

Verapamil slows down the process of removing lovastatin from your body. This can cause lovastatin to reach high levels that increase the risk of muscle injury.

Understanding the Lovastatin and Verapamil Interaction

FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Lovastatin belongs to the HMG-CoA Reductase Inhibitor (Statin) class and Verapamil belongs to the Calcium Channel Blocker class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Verapamil slows down the process of removing lovastatin from your body. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.

Context around a specific patient determines real-world impact. Lovastatin has 30 total documented interactions on file in this dataset, and Verapamil has 57. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Your doctor may need to limit your dose of lovastatin while you are on this medication. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.

An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Lovastatin or Verapamil based on a web page, speak with your prescriber or pharmacist before making any change.
