Rivaroxaban is an anticoagulant medication that helps prevent blood clots. It works by inhibiting a specific protein in the blood called Factor Xa, which plays a crucial role in the clotting process. This makes it useful for treating conditions like deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as for reducing the risk of stroke in patients with certain heart conditions. Rivaroxaban is typically taken as a tablet and can be prescribed for both short-term and long-term use. Patients using this medication should follow their healthcare provider's instructions carefully and be aware of potential side effects, such as bleeding or bruising. Regular monitoring may be necessary to ensure safety and effectiveness.
