Xarelto (rivaroxaban) is a prescription drug anticoagulant, or blood thinner. The medication is produced by Janssen Pharmaceuticals, Inc. (a Johnson & Johnson company), under license from Bayer HealthCare AG of Germany. Xarelto was approved by the Food and Drug Administration (FDA) to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation.
Xarelto is in a class of medications called factor Xa inhibitors. It works by decreasing the clotting ability of the blood. Like other newer blood thinners, it does not require regular monitoring of the blood.
