Combining Fondaparinux Sodium and Indomethacin is a major interaction and should generally be avoided without close medical supervision.
Combining indomethacin with fondaparinux significantly increases your risk of serious bleeding, including internal bleeding. Your doctor will likely avoid this combination.
Mechanism: Indomethacin, a non-selective NSAID, inhibits cyclooxygenase (COX-1 and COX-2) enzymes, leading to reduced prostaglandin synthesis and impaired platelet aggregation. Fondaparinux is a selective factor Xa inhibitor, which prevents thrombin generation and clot formation. The concomitant use results in additive antihemostatic effects, primarily through impaired platelet function from the NSAID and direct anticoagulant action from fondaparinux.

Fondaparinux Sodium Overview
Fondaparinux sodium is a medication that helps prevent and treat blood clots. It works by thinning the blood, specifically by blocking a substance in the body called Factor Xa, which is involved in clot formation. This medicine is used to prevent deep vein thrombosis (DVT) after major surgeries like hip, knee, or abdominal surgery, and also to treat existing DVT or pulmonary embolism (PE).

Fondaparinux Sodium
The antithrombotic activity of fondaparinux sodium is the result of antithrombin III (ATIII)-mediated selective inhibition of Factor Xa. By selectively binding to ATIII, fondaparinux sodium potentiates (about 300 times) the innate neutralization of Factor Xa by ATIII. Neutralization of Factor Xa interrupts the blood coagulation cascade and thus inhibits thrombin formation and thrombus development. Fondaparinux sodium does not inactivate thrombin (activated Factor II) and…
