Amiodarone and Ezetimibe Interaction

Drug interaction information between Amiodarone and Ezetimibe.

Amiodarone and Ezetimibe have a documented major interaction in FDA labeling.

FDA drug labeling documents a major-severity interaction between Amiodarone and Ezetimibe. 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

Amiodarone

Class III Antiarrhythmic

Drug B

Ezetimibe

Cholesterol Absorption Inhibitor

How They Interact

Taking these drugs together can cause the cholesterol medicine to build up in your body, which increases the risk of serious muscle damage.

What To Do

Your doctor should limit your dose of ezetimibe and simvastatin to no more than 10 mg/20 mg daily.

FDA Label Information

Amiodarone, Dronedarone, Ranolazine, or Calcium Channel Blockers Clinical Impact: The risk of myopathy and rhabdomyolysis is increased by concomitant use of amiodarone, dronedarone, ranolazine, or calcium channel blockers with ezetimibe and simvastatin. For patients taking amiodarone, amlodipine, or ranolazine, do not exceed ezetimibe and simvastatin 10 mg/20 mg daily [see Dosage and Administration ( 2.3 )].

Understanding the Amiodarone and Ezetimibe Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Amiodarone belongs to the Class III Antiarrhythmic class and Ezetimibe belongs to the Cholesterol Absorption Inhibitor class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Taking these drugs together can cause the cholesterol medicine to build up in your body, which increases the risk of serious muscle damage. 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. Amiodarone has 42 total documented interactions on file in this dataset, and Ezetimibe has 25. 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 should limit your dose of ezetimibe and simvastatin to no more than 10 mg/20 mg daily. 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 Amiodarone or Ezetimibe based on a web page, speak with your prescriber or pharmacist before making any change.
