You should not take warfarin if you are allergic to it, or if you have:
- hemophilia or any bleeding disorder that is inherited or caused by disease;
- a blood cell disorder such as anemia (lack of red blood cells) or a low level of platelets in your blood;
- blood in your urine or stools, or if you have been coughing up blood;
- an infection of the lining of your heart (also called bacterial endocarditis);
- stomach or intestinal bleeding or ulcer;
- recent head injury, aneurysm, or bleeding in the brain;
- if you have recently had or will soon have any type of surgery (especially brain, spine, or eye surgery); or
- if you undergo a spinal tap or receive spinal anesthesia (epidural).
You should not take warfarin if you cannot be reliable in taking it because of alcoholism, psychiatric problems, dementia, or similar conditions.
Warfarin may cause you to bleed more easily, especially if you have:
- a history of bleeding problems;
- high blood pressure or severe heart disease;
- kidney or liver disease;
- surgery or a medical emergency;
- a disease affecting the blood vessels in your brain;
- a history of stomach or intestinal bleeding;
- if you are 65 or older; or
- if you are severely ill or debilitated.
To make sure you can safely take warfarin, tell your doctor if you have any of these other conditions:
- celiac sprue (an intestinal disorder);
- congestive heart failure;
- overactive thyroid;
- a connective tissue disorder such as Marfan Syndrome, Sjogren syndrome, scleroderma, rheumatoid arthritis, or lupus; or
- if you have ever had low blood platelets after receiving heparin.
Follow your doctor's instructions about taking warfarin while you are pregnant. Warfarin can harm an unborn baby or cause birth defects. However, the benefits of preventing blood clots in certain women may outweigh any risks to the baby. Tell your doctor right away if you become pregnant during treatment. Use effective birth control while you are using this medication.
It is not known whether warfarin passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take warfarin (Coumadin)?
Follow the directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Never take a double dose of this medication.

Call your doctor if you have any illness with diarrhea, fever, chills, body aches, or flu symptoms.
While taking warfarin, your blood will need to be tested often. Visit your doctor regularly.
Wear a medical alert tag or carry an ID card stating that you take warfarin. Any doctor, dentist, surgeon, or other medical care provider who treats you should know that you are taking this medication.
