Xarelto (rivaroxaban) is an oral anticoagulant and Factor Xa inhibitor used to treat deep vein thrombosis (DVT) by blocking a key step in the blood clotting process and preventing the clot from growing or traveling to the lungs. One advantage is that it is taken as a pill and does not require routine blood monitoring, unlike older medications such as warfarin. It’s often chosen because it has simple dosing and is taken once daily after the initial treatment phase, which can be more convenient than some other Factor Xa inhibitors. It is commonly started at a higher dose initially and then reduced after the first few weeks of treatment.
