Common Use

This medication suppresses the effects of vitamin K, which plays a key role in blood clotting. By doing so, it helps prevent the formation of blood clots. Blood clots can develop in various parts of the body, such as the extremities after prolonged immobility, the lungs causing pulmonary embolism, or around artificial heart valves, leading to symptoms like shortness of breath and chest pain. Coumadin is commonly prescribed to treat blood clots in the lower extremities, pulmonary embolism, atrial fibrillation, and for certain orthopedic surgeries like knee or hip replacements, as well as following myocardial infarction.
