Combining Diclofenac Sodium and Warfarin is a major interaction and should generally be avoided without close medical supervision.
Taking diclofenac, an anti-inflammatory pain reliever, with warfarin, a blood thinner, significantly increases your risk of serious bleeding, including stomach bleeding. Your doctor will likely recommend avoiding this combination.
Mechanism: Diclofenac inhibits cyclooxygenase enzymes, reducing prostaglandin synthesis, which impairs platelet function and can damage the gastrointestinal mucosa. Warfarin works by blocking vitamin K-dependent clotting factors, leading to a decreased ability of blood to clot. The combination results in additive antiplatelet effects and increased gastrointestinal toxicity, potentiating the anticoagulant effect of warfarin.

Diclofenac Sodium
Diclofenac has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of diclofenac sodium, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Diclofenac is a potent inhibitor of prostaglandin synthesis in vitro. Diclofenac concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in induc…
