Xarelto 2.5 mg Tablet is used to prevent and treat deep vein thrombosis (blood clots in leg veins) and pulmonary embolism (blood clots in the lung) by reducing blood clot formation. It contains Rivaroxaban, which works by inhibiting the production of clotting factors by decreasing the action of vitamin K. This prevents the conversion of fibrinogen (soluble protein) to fibrin (insoluble protein), thereby preventing blood clots formation. You may experience bleeding, anemia (low number of red blood cells), and nausea. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
