Combining Piroxicam and Warfarin is a major interaction and should generally be avoided without close medical supervision.
Combining piroxicam with warfarin significantly increases your risk of bleeding, including serious internal bleeding. Your doctor will likely avoid this combination due to the high risk.
Mechanism: Piroxicam, a non-selective NSAID, inhibits cyclooxygenase enzymes, reducing prostaglandin synthesis. This leads to decreased platelet aggregation and can cause gastrointestinal mucosal damage. Warfarin is an anticoagulant that inhibits vitamin K-dependent clotting factors. The concurrent use results in an additive antiplatelet effect and impaired coagulation, exacerbated by potential GI irritation from the NSAID.

Piroxicam
Piroxicam has analgesic, anti-inflammatory, and antipyretic properties.

Piroxicam is a potent inhibitor of prostaglandin (PG) synthesis in vitro. Piroxicam concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in in…
