Warfarin / Coumadin®:
What it is and What it Does
 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
How to Take Warfarin
 Take warfarin at the same time every day as
directed by the Anticoagulation Clinic.

remember, as long as it is the same day.
 Never skip a dose or take a double dose.
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

regularly as directed by the Anticoagulation
