Nicardipine and Naproxen have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Nicardipine and Naproxen. 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
Naproxen does not affect how nicardipine sticks to proteins in the blood.
What To Do
No special precautions or dose changes are required for this combination.

Understanding the Nicardipine and Naproxen 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 Naproxen belongs to the Nonsteroidal Anti-Inflammatory Drug (NSAID) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Naproxen does not affect how nicardipine sticks to proteins in the blood. 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 Naproxen has 23. 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: No special precautions or dose changes are required for this combination. 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 Nicardipine or Naproxen based on a web page, speak with your prescriber or pharmacist before making any change.
