Oxaprozin and Meloxicam Interaction
Drug interaction information between Oxaprozin and Meloxicam.
Oxaprozin and Meloxicam have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Oxaprozin and Meloxicam. 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
Both drugs belong to the same family of medicines called NSAIDs, and taking them together is like taking a double dose. This increases the risk of side effects like stomach ulcers and kidney problems without providing extra pain relief.
What To Do
Avoid taking these two medications together. Talk to your doctor about using only one type of NSAID to manage your symptoms safely.
FDA Label Information
In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration.

Understanding the Oxaprozin and Meloxicam Interaction
FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Oxaprozin belongs to the Nonsteroidal Anti-Inflammatory Drug (NSAID) class and Meloxicam belongs to the Nonsteroidal Anti-Inflammatory Drug (NSAID) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Both drugs belong to the same family of medicines called NSAIDs, and taking them together is like taking a double dose. 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. Oxaprozin has 15 total documented interactions on file in this dataset, and Meloxicam has 17. 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: Avoid taking these two medications together. 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 Oxaprozin or Meloxicam based on a web page, speak with your prescriber or pharmacist before making any change.
