What is Coumadin
 Coumadin
is an anticoagulant (blood thinner).
Coumadin
reduces the formation of blood clots, which is important in
the prevention of heart attacks, strokes, and blockage of
major veins and arteries.
Coumadin
may also be used for purposes other than those listed in this
medication guide.
General medical information about Coumadin
Never take a double dose of this medication.
Do not take aspirin or nonsteroidal anti-inflammatory drugs
(NSAIDs) such as ibuprofen (Motrin, Advil, Nuprin, others),
ketoprofen (Orudis, Orudis KT, Oruvail), naproxen (Naprosyn,
Aleve, Anaprox), and others while taking Coumadin, except
under the direction of your doctor. These medicines increase
the risk of bleeding.
Avoid sudden changes in your
diet. Vitamin K decreases the effects of Coumadin. Large
amounts of vitamin K are found in foods such as liver, broccoli,
brussels sprouts, and green leafy vegetables (e.g., spinach,
Swiss chard, coriander, collards, cabbage). Do not change
the amount of these foods in your diet without first talking
to your doctor.
It will be necessary to regularly
monitor your therapy with a blood test called a "PT"
or an "INR." These tests help to determine the
amount of Coumadin that you need to take.

your doctor if you experience any unusual bruises or heavily
bleeding wounds, diarrhea, infection, or fever during treatment
