Apixaban is an oral 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 reducing the risk of stroke in patients with atrial fibrillation and for treating or preventing deep vein thrombosis and pulmonary embolism. Apixaban is typically taken twice daily and does not require regular blood monitoring, unlike some other anticoagulants. Common side effects may include bleeding, bruising, and gastrointestinal issues. Patients should inform their healthcare provider about any other medications they are taking to avoid potential interactions.
