Warfarin, also known as Coumadin, is the most common medication used to prevent blood clots. It has many uses, and may be given to patients before surgery, to help manage heart disease, or to people with a history of blood clots. Despite its usefulness, warfarin may affect people differently and patients need to be watched closely to make sure each dose is working safely.
Regular anticoagulation checkups help you better monitor your medicine and get better results because you get immediate feedback and education about ways to avoid reactions.
