Rivaroxaban is used to prevent blood clots from forming due to a certain irregular heartbeat (atrial fibrillation) or after hip or knee replacement surgery. It is also used to prevent blood clots from forming in high-risk patients with limited mobility during their hospital stay and after discharge. In addition, rivaroxaban is used to treat blood clots (such as in deep vein thrombosis-DVT or pulmonary embolus-PE) and to prevent the blood clots from forming again. Rivaroxaban may be used in children to prevent blood clots from forming after a certain heart surgery (Fontan procedure).

Rivaroxaban is an anticoagulant that works by blocking certain clotting proteins in your blood.
