Brand names: Coumadin, Jantoven, Marevan, Waran
Warfarin (brand names Coumadin, Jantoven, Marevan, Waran) is an anticoagulant. Warfarin is a synthetic derivative of coumarin, a chemical found naturally in many plants. Warfarin reduces the formation of blood clots by blocking the formation of certain clotting factors. Warfarin is used to prevent heart attacks, strokes, and blood clots in veins, arteries and lungs. Warfarin is also used to reduce the risk of death or blood clotting events after a heart attack.

What are warfarin tablets?
WARFARIN (Coumadin®) is an anticoagulant. Warfarin helps to treat or prevent clots in the veins, arteries, lungs, or heart. Warfarin stops clots from forming or getting bigger, and lets the body naturally dissolve the clots. Sometimes warfarin is called a blood thinner because you may bleed more easily while taking it; however, warfarin does not actually thin the blood.
What should I tell my health care provider before I take this medicine?
They need to know if you have any of these conditions:
If you frequently drink alcohol-containing beverage
blood disease, bleeding disorders, hemorrhage, hemophilia or aneurysm
bowel disease, diverticulitis, or ulcers
heart valve infection
high blood pressure
protein or vitamin deficiency
an unusual or allergic reaction to warfarin, other medicines, foods, dyes, or preservatives
pregnant or trying to get pregnant
How should I take this medicine?
Take warfarin tablets by mouth. Follow the directions on the prescription label. Warfarin is usually taken once a day. Swallow the tablets with a drink of water. Take your dose at the same time each day. Record your daily dose on a calendar when you take it. Do not take warfarin more often than directed.
What if I miss a dose?
Try not to miss doses. If you do miss a dose, take it as soon as you can that same day. If it is almost time for your next dose, take only that dose. Do not double doses, and do not take two doses in one day unless your prescriber or health care professional tells you to; this can increase the risk of bleeding. If you miss a dose, record the date of the missed dose and tell your prescriber or health care professional at your next visit. If you miss doses for two or more days, call your doctor for instructions.

Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
What side effects might I notice from taking warfarin?

What should I watch for while taking warfarin?
Visit your prescriber or health care professional for regular checks on your progress. You will need to have your blood checked regularly to make sure you are getting the right dose of warfarin. The blood test that is used to monitor warfarin therapy is called the protime (PT) or INR. Your prescriber or health care professional will check your PT or INR and decide whether or not your dose of warfarin needs to be changed. When you first start warfarin, these tests are done frequently. Once the correct dose is determined and you take your medication properly, these tests can be done less often.
While you are taking warfarin, carry an identification card with your name, the name and dose of medicine(s) being used, and the name and phone number of your prescriber or health care professional or person to contact in an emergency.
You should discuss your diet with your prescriber or health care professional. Many foods contain high amounts of vitamin K, which can interfere with the effect of warfarin. Your prescriber or health care professional may want you to limit your intake of foods that contain vitamin K. Foods that have moderate to high amounts of vitamin K include brussel sprouts, kale, green tea, asparagus, avocado, broccoli, cabbage, cauliflower, collard greens, liver, soybean oil, soybeans, certain beans, mustard greens, peas (blackeyed peas, split peas, chick peas), turnip greens, parsley, green onions, spinach, and lettuce.
Warfarin can cause birth defects or bleeding in an unborn child. Women of childbearing age should use effective contraception while receiving warfarin therapy. If a woman becomes pregnant while taking warfarin, she should discuss the potential risks and her options with her health care professional.
Do not change brands of warfarin without talking to your prescriber or health care professional. Also, always check the color of your medicine when you get a new prescription. If you notice a change in the color of your warfarin tablet, check with your pharmacist or health care professional to make sure you received the correct medicine.
Alcohol can affect the way warfarin works. Ask your prescriber or health care professional how much, if any, alcohol you may consume.
Do not take any over-the-counter medicines without first talking to your prescriber or health care professional. Do not take any aspirin or aspirin-containing products, ibuprofen (Motrin®, Advil®, or Nuprin®) naprosyn (Aleve®), ketoprofen (Orudis-KT®) or other medicines known as nonsteroidal anti-inflammatory agents without talking to your prescriber or health care professional first.
Be careful to avoid sports and activities that might cause injury while you are using warfarin. Severe falls or injuries can cause unseen bleeding. Be careful when using sharp tools or knives. Consider using an electric razor. Take special care brushing or flossing your teeth. Report any injuries, bruising, or red spots on the skin to your prescriber or health care professional.
If you have an illness that causes vomiting, diarrhea, or fever for more than a few days, contact your doctor. Also check with your doctor if you are unable to eat for several days. These problems can change the effect of warfarin.
Even after you stop taking warfarin, it takes several days before your body recovers its normal ability to clot blood. Ask your prescriber or health care professional how long you need to be cautious. If you are going to have surgery or dental work, tell your prescriber or health care professional that you have been taking warfarin.

Frequently asked questions:
What is a generic medication?
Wikipedia gives the following definition: “Generic drug (pl. generic drugs, short: generics) is a drug which is produced and distributed without a brand name. A generic must contain the same active ingredients as the original formulation. In most cases, it is considered bioequivalent to the brand name counterpart with respect to pharmacokinetic and pharmacodynamic properties. By extension, therefore, generics are assumed to be identical in dose, strength, route of administration, safety, efficacy, and intended use. Mind that the pills you will receive from us differ in appearance from the brand name ones. The looks of medications as well as brand names are the intellectual property of the brand manufacturer. Thus to avoid any accusation of copyright infringement we have to change the shape and the color of the generic pills as well as use the name of the active ingredient (generic name) instead of the brand name for printing on pills. Please be aware that the generic pills differ in appearance from the brand name medications. Our pills are round shaped and blister packed (10 pills per each blister). The name of the active ingredient as well as the weight are specified on the pill itself.
Why are generic pills cheaper than the brand name ones?
The principal reason for the reduced price of generic medicines is that the creation of the generic drug runs up less cost and therefore a lower price can be offered and still maintain profitability.
Manufacturers of generic drugs are mainly able to avoid the following three costs that brand name pharmaceutical companies incur: (1) costs associated with the research and development of the drug; (2) costs associated obtaining regulatory approval (i.e. proving safety and efficacy of a drug); and (3) marketing costs.
First, Generic manufacturers do not incur the cost of drug discovery and instead reverse-engineer existing brand name drugs to allow them to manufacture bioequivalent versions.
Second, generic manufacturers do not bear the burden of proving the safety and efficacy of the drugs through clinical trials - rather, generic manufacturers must prove the generic drug’s bioequivalancy to the existing drug.
Third, these companies receive the large benefit of the marketing and advertising that goes into pushing the innovator drug. The brand name drug has to prove itself in the eyes of the consumer, generic ones do not. The drugs that generic manufacturers are selling have been on the market for usually a decade or more and do not need additional advertising. For the same reason, generic manufacturers also do not give away sample doses to promote their products. The significant research, development and marketing costs incurred by the large pharmaceutical companies in introducing a new drug to the market is often cited as the reason for the high cost of new agents - they wish to recover these costs before the patent expires. Generic manufacturers do not incur these costs, with bioequivalence testing and manufacturing costing relatively little, and are able to charge significantly less than the brand.
