Combining Naproxen and Rivaroxaban is a major interaction and should generally be avoided without close medical supervision.
Combining naproxen with rivaroxaban significantly increases your risk of bleeding, especially from the stomach or intestines. This combination should generally be avoided due to the serious potential for harm.
Mechanism: Naproxen, a non-steroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis and impairing platelet aggregation, while also causing direct gastric irritation. Rivaroxaban is a direct oral anticoagulant (DOAC) that selectively inhibits Factor Xa, preventing thrombin generation and clot formation. The concomitant use of these agents results in additive antiplatelet and anticoagulant effects, leading to a synergistic increase in bleeding risk.

Naproxen
Naproxen has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of naproxen, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in ani…
Rivaroxaban
Rivaroxaban is a selective inhibitor of FXa. It does not require a cofactor (such as Anti-thrombin III) for activity. Rivaroxaban inhibits free FXa and prothrombinase activity. Rivaroxaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, rivaroxaban decreases thrombin generation.
