Nicardipine and Propranolol Interaction

Drug interaction information between Nicardipine and Propranolol.

Nicardipine and Propranolol have a documented minor interaction in FDA labeling.

FDA drug labeling documents a minor-severity interaction between Nicardipine and Propranolol. 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

Nicardipine

Calcium Channel Blocker

Drug B

Propranolol

Non-Selective Beta-Blocker

How They Interact

Propranolol does not change the way nicardipine binds to proteins in your bloodstream.

What To Do

You can typically take these two drugs together without needing a dose adjustment.

FDA Label Information

When therapeutic concentrations of furosemide, propranolol, dipyridamole, warfarin, quinidine or naproxen were added to human plasma (in vitro), the plasma protein binding of nicardipine hydrochloride capsules were not altered.

Frequently Asked Questions

Why do Nicardipine and Propranolol interact?

Propranolol does not change the way nicardipine binds to proteins in your bloodstream.

Understanding the Nicardipine and Propranolol Interaction

FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Nicardipine belongs to the Calcium Channel Blocker class and Propranolol belongs to the Non-Selective Beta-Blocker class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Propranolol does not change the way nicardipine binds to proteins in your bloodstream. 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. Nicardipine has 14 total documented interactions on file in this dataset, and Propranolol has 44. 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: You can typically take these two drugs together without needing a dose adjustment. 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 Nicardipine or Propranolol based on a web page, speak with your prescriber or pharmacist before making any change.
