Coumadin rx is an anticoagulant (blood thinner). It is prescribed to:
* Prevent and/or treat a blood clot that has formed within a blood
vessel or in the lungs.
* Prevent and/or treat blood clots associated with certain heart conditions
or replacement of a heart valve.
* Aid in the prevention of blood clots that may form in blood vessels anywhere
in the body after a heart attack.
* Reduce the risk of death, another heart attack, or stroke after a heart attack.
Most important fact about Coumadin rx without a prescriptions
The most serious risks associated with Coumadin rx treatment are hemorrhage
(severe bleeding resulting in the loss of a large amount of blood)
in any tissue or organ and, less frequently, the destruction of skin
tissue cells (necrosis) or gangrene. The risk of hemorrhage usually
depends on the dosage and length of treatment with Coumadin rx.
Hemorrhage and necrosis have been reported to result in death or permanent
disability. Severe necrosis can lead to the removal of damaged tissue
or amputation of a limb. Necrosis appears to be associated with blood
clots located in the area of tissue damage and usually occurs within
a few days of starting Coumadin rx treatment. How should you take Coumadin rx?
The objective of treatment with a blood-thinner is to control the
blood-clotting process without causing severe bleeding, so that a clot
does not form and cut off the blood supply necessary for normal body
function. Therefore, it is very important that you take this medication
exactly as prescribed by your doctor and that your doctor monitor your
condition on a regular basis. Be especially careful to stick to the
exact dosage schedule your doctor prescribes.
Effective treatment with minimal complications depends on your cooperation
and communication with the doctor.
Do not take or discontinue any other medication unless directed to
do so by your doctor. Avoid alcohol, salicylates such as aspirin, larger
than usual amounts of foods rich in vitamin K (including liver, vegetable
oil, egg yolks, and green leafy vegetables), which can counteract the
effect of Coumadin rx, or any other drastic change in diet.
Note that Coumadin rx often turns urine reddish-orange.
You should carry an identification card that indicates you are taking
Coumadin rx.
If you miss a dose...
Take the forgotten dose as soon as you remember, then go back to your
regular schedule. If you do not remember until the next day, skip the
dose. Never try to "catch up" by doubling the dose. Keep
a record for your doctor of any doses you miss.
Storage instructions...
Coumadin rx can be stored at room temperature. Close the container tightly
and protect from light. Coumadin (Warfarin) side effects

causing the blockage of a blood vessel. If you notice any of the following
symptoms, contact your doctor immediately:
Abdominal pain; abrupt and intense pain in the leg, foot, or toes;
blood in the urine; bluish mottling of the skin of the legs and hands;
foot ulcers; gangrene; high blood pressure; muscle pain; "purple
toes syndrome" (see below); rash; or thigh or back pain.

or she will have to consider the risks against the benefits before
giving you Coumadin rx.
An infectious disease or intestinal disorder
A history of recurrent blood clot disorders in you or your family
An implanted catheter
Dental procedures
Inflammation of a blood vessel
Moderate to severe high blood pressure
Moderate to severe kidney or liver dysfunction
Polycythemia vera (blood disorder)
Severe diabetes
Surgery or injury that leaves large raw surfaces
Trauma or injury that may result in internal bleeding
Purple toes syndrome can occur when taking Coumadin rx, usually 3 to
10 weeks after the start of anticoagulation therapy. Symptoms include
dark purplish or mottled color of the toes that turns white when pressure
is applied and fades when you elevate your legs, pain and tenderness
of the toes, and change in intensity of the color over a period of
time. If any of these symptoms develop, notify your doctor immediately.
If you are taking Coumadin rx, your doctor should periodically check
the time it takes for your blood to start the clotting process (prothrombin
time). Numerous factors such as travel and changes in diet, environment,
physical state, and medication may alter your response to treatment
with an anticoagulant. Clotting time should also be monitored after
your release from the hospital and whenever other medications are started,
discontinued, or taken sporadically.

an injury. Remain cautious after you stop taking Coumadin rx. It will
continue to work for 2 to 5 days.

have you tested regularly.

fever develops; if any unusual symptoms, such as pain, swelling, or
discomfort, appear; or if you see prolonged bleeding from cuts, increased
menstrual flow, vaginal bleeding, nosebleeds, bleeding of gums from
brushing, unusual bleeding or bruising, red or dark brown urine, red
or tarry black stool, headache, dizziness, or weakness. Possible food and drug interactions when taking Coumadin
