3 Warfarin / Coumadin ® : What it is and What it Does What is warfarin? An anticoagulant that helps reduce the formation of clots in your blood Why was warfarin prescribed for you? Sometimes medical conditions can make blood clot too easily and quickly This could cause serious health problems because clots can block the flow of blood to the heart or brain Warfarin can prevent harmful clots from forming

4 How does warfarin work? Blood clots are formed through a series of chemical reactions in your body. Vitamin K is necessary for those reactions. Warfarin works by decreasing the activity of vitamin K which lengthens the time it takes for a clot to form Warfarin / Coumadin ® : What it is and What it Does

5 How to Take Warfarin Take warfarin at the same time every day as directed by the Anticoagulation Clinic. Warfarin can be taken with food or other medications. If you forget a dose, take it as soon as you remember, as long as it is the same day. Never skip a dose or take a double dose.

6 Blood Tests How much warfarin you need will depend upon the results of your blood tests The International Normalized Ratio (INR) is the blood test we will use to evaluate how long it takes your blood to clot You will need to get your INR checked regularly as directed by the Anticoagulation Clinic
