Short Overview of Coumadin (Warfarin)
Coumadin, also known by its generic name Warfarin, is a commonly prescribed anticoagulant medication used to prevent blood clots in patients at risk for stroke, heart attack, and deep vein thrombosis. It belongs to a class of medications called vitamin K antagonists and works by blocking the formation of clotting factors in the liver.
When a patient is prescribed Coumadin, they are typically monitored regularly through blood tests to ensure that their international normalized ratio (INR) falls within the therapeutic range. This helps prevent both bleeding and clotting complications.
Coumadin is available in tablet form and is usually taken once a day at the same time. It is essential for patients to adhere to their prescribed dosage and follow-up appointments to ensure the medication’s effectiveness.
Common side effects of Coumadin include bruising, bleeding gums, and nosebleeds. In cases of bleeding episodes or significant changes in health status, patients are advised to seek medical attention promptly.
