Xarelto is a brand name for rivaroxaban, an oral anticoagulant developed by Bayer and Janssen Pharmaceuticals. Approved by the FDA in 2011, Xarelto is used to prevent and treat various types of blood clots. It works by directly inhibiting Factor Xa, an enzyme crucial for blood clotting. Xarelto is commonly prescribed for conditions such as atrial fibrillation, deep vein thrombosis, pulmonary embolism, and to prevent blood clots after certain surgeries. Known for its convenient once-daily dosing, Xarelto typically does not require routine blood monitoring, but it is important to follow dosage instructions carefully to manage bleeding risks.
