How does this medication work? What will it do for me?Rivaroxaban belongs to the family of medications called anticoagulants. Anticoagulants prevent harmful blood clots from forming in the blood vessels by reducing the ability of the blood to clot. Rivaroxaban is used to prevent blood clots for people who have had total hip replacement or knee replacement surgery. It is used to treat blood clots for people who have had a deep vein thrombosis (DVT; a blood clot in the major arteries, particularly the leg) or pulmonary embolism (blood clot in the lung), and to prevent these clots from happening again.
Rivaroxaban is also used to prevent stroke or blood clots in people with atrial fibrillation.
