Methotrexate and Meloxicam Interaction
Drug interaction information between Methotrexate and Meloxicam.
Methotrexate and Meloxicam have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Methotrexate 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
Meloxicam can cause methotrexate to build up in your body to unsafe levels. This can lead to serious issues like low blood cell counts and kidney damage.
What To Do
Your doctor should monitor you closely for signs of drug toxicity while you are taking both medications. You may need frequent blood tests to check your kidneys and blood.
FDA Label Information
Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). Intervention: During concomitant use of meloxicam and methotrexate, monitor patients for methotrexate toxicity.

Understanding the Methotrexate and Meloxicam Interaction
FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Methotrexate belongs to the Disease-Modifying Antirheumatic Drug (DMARD) 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: Meloxicam can cause methotrexate to build up in your body to unsafe levels. 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. Methotrexate has 38 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: Your doctor should monitor you closely for signs of drug toxicity while you are taking both medications. 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 Methotrexate or Meloxicam based on a web page, speak with your prescriber or pharmacist before making any change.
