Anticoagulation therapy is a medical treatment that helps prevent blood clots from forming or growing larger. This therapy is often used for patients with conditions like deep vein thrombosis or atrial fibrillation, where the risk of clot formation is higher. Common anticoagulants include medications like warfarin and heparin, which work by interfering with the blood's clotting process. Patients on anticoagulation therapy require regular monitoring to ensure the medication is effective and to minimize the risk of bleeding complications. Healthcare providers may adjust dosages based on factors such as blood tests and individual patient needs, ensuring safe and effective treatment.
