Summary
Meloxicam impairs platelet function and can cause gastrointestinal ulceration, which substantially increases bleeding risk in patients on warfarin. Meloxicam may also modestly affect INR.
What this interaction means in plain words
Meloxicam and Warfarin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Meloxicam belongs to Musculoskeletal; Warfarin belongs to Cardiovascular.
Why it happens
Additive hemostatic impairment through NSAID platelet inhibition and mucosal injury plus vitamin K antagonist anticoagulation, with possible minor protein binding or CYP2C9 effects.
What to do
Avoid the combination where possible and use paracetamol or topical options. If unavoidable, monitor INR closely, watch for bleeding and consider a proton pump inhibitor.
