Coumadin is one of the anticoagulant medications that are mainly used to prevent blood clots from forming and increasing in size in the body. This medication works by inhibiting the natural blood clotting process, which contributes to reducing the risk of blockage of blood vessels. Coumadin has multiple uses based on the medical conditions that require reducing the risk of clots. It helps in preventing and treating deep vein thrombosis (DVT), which can lead to serious complications such as pulmonary embolism if the clot moves to the lungs.
Coumadin is also used to prevent clots associated with atrial fibrillation, which is a heart rhythm disorder that increases the chances of clots forming and moving to the brain, which may cause a stroke.
