Metoprolol and Verapamil Interaction
Drug interaction information between Metoprolol and Verapamil.
Metoprolol and Verapamil have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Metoprolol 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.
How They Interact
These drugs both work to lower your heart rate and slow down the electrical conduction in your heart. Using them at the same time increases the risk of your heart rate becoming dangerously slow.
What To Do
Your healthcare provider should check your heart rhythm regularly. Your doctor may need to adjust your dosages to ensure your heart rate stays in a safe range.

Understanding the Metoprolol and Verapamil Interaction
FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Metoprolol belongs to the Beta-Blocker 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: These drugs both work to lower your heart rate and slow down the electrical conduction in your heart. 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. Metoprolol has 18 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 healthcare provider should check your heart rhythm regularly. 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.

Never start, stop, or adjust either Metoprolol or Verapamil based on a web page, speak with your prescriber or pharmacist before making any change.
