Coumadin Brand is Being Discontinued – Generic Warfarin is Still Available

Bristol-Myers Squibb announced that the sale and distribution of all strengths of Coumadin (Warfarin Sodium) tablets will be discontinued in the United States, Canada, Latin America, and Saudi Arabia, due to an unexpected manufacturing issue. It will begin on June 1, 2020 . Original source: https://www.bms.com/assets/bms/ca/documents/productmonograph/CANADA-Coumadin-deletion_D-HCP-Communication_FINAL_EN_04.23.2020.pdf


COUMADIN (warfarin sodium) is a prescription medication that interferes with normal blood clotting (coagulation). It is also called an anticoagulant. 

Millions of people depend on anticoagulants – also known as “blood thinners” – to prevent life-threatening blood clots. While these medications do not actually “thin” the blood, they do slow the body’s ability to form dangerous blood clots, such as blood clots in the arms or legs (deep vein thrombosis or DVT) and blood clots in the lungs (pulmonary embolism or PE).


Stopping blood thinners can increase your risk for blood clots, due to the underlying risk factor(s) for which your blood thinner was originally prescribed. These bleeding and clotting risks can be complicated for your healthcare providers to manage.

For patients currently using Coumadin® (warfarin sodium) tablets, healthcare providers will be required to consider alternatives. Prescribing an alternate product is the clinical decision of the healthcare professional in consultation with the patient.

The generic version of Coumadin® is one option. Even though generic warfarin and brand name Coumadin® are considered interchangeable, your health care provider may want you to have your levels checked when making a change like this.  Therefore, it is important to have this discussion with your healthcare team.

In Canada, therapeutic alternatives, including generics, are available. Please check the following information.

  1. Due to an unexpected manufacturing issue that cannot be resolved Coumadin is no longer available. Seriously?!?!?!?! Is profitability more important than someone’s life who is dependent upon Coumadin? Apparently so.

    • Thank you for your feedback. Although it can be frustrating for some to find out that brand name Coumadin is being discontinued, the generic version of Coumadin (warfarin) is and has been available in Canada for many years. As the article states, there are alternatives that may work for you. This article was posted to create awareness and to encourage people to engage their physicians with this information. We recommend you have a discussion with your physician regarding any changes that may be possible considering Coumadin brand name is being discontinued

      • This is horrific!!! The generic cause more INR instability thus requiring more lab tests. The US drug companies are greedy monsters!

        • Warfarin sodium is MUCH cheaper. I have been taking Coumadin for years…it is now $270.00 for a 90 day supply. Warfarin is $6 for 90 days supply..
          I do my own INR on a little machine provided thru ny cardiologist office..
          I do agree that the pharmaceutical companies are greedy monsters.

        • I agree. This is the reason I take Coumadin because Warfarin causes my INR to go dangerously high in a short period of time…

      • Generic warfarin is NOT the same! It is made up of different binders that do interfere with its blood thinning capabilities. Also current investigations into Generic medications coming out of China have revealed high levels of known carcinogen has been a constant finding in generic medications. Many people have died from cancer caused by there generic medications including the generic form of valsartin known to have killed over 500,000 people as an investigation this year revealed. Also investigators learned that too often the key ingredients of these generic medications were not measured correctly. With a blood thinner it’s critical that a 4 mg tablet only have 4 mg of its main ingredient. What is happening is that people who take generic warfarin have a difficult time keeping the INR LEVELS ACCURATE! Example one week I would be at a 2.5 INR the following with the exact same dose my INR was at 7.5 a deadly level as internal organs began to bleed out. Other times the levels would bounce the opposite direction and my INR would drop to 1.0 basically non existent blood thinning and I had to deal with life threatening DVT BLOOD CLOTS.
        Absolutely this is an outrage for a manufacture to be so careless in regards to a life saving medication that for many who can not take the new series of daily blood thinning medications out now because those thin on the wrong playlet levels for people with FULL HETEROZYGOUS FACTOR V LEIDEN blood clotting disorder. I will be finding alternative brands for any other medications I currently take that are made by this clown manufacturer as I will not give them another dime of bussiness in my name!

    • Really this is a real blow to me as I have been on coumadin (jantoven) for 28 years for a mechanical heart valve. It is the only drug that keeps my INR stable. Have you really done research on this.you are putting many people’s lives in jeopardy.

  2. All about money. They want people to switch to Eliquis which is $500/month. What manufacturing issue could cause them to discontinue manufacturing of a drug they’ve been making for decades? They should give more details if it’s not. Still available all over Europe. Pitiful. Brand Name Coumadin shows better INR control in some individuals. This will have a potentially damaging impact on those people.

    • It is all about money. I have tried other drugs and all have failed.
      Coumadin is literally keeping me alive. Until it directly impacts them they will never understand. Manufacturers could care less about anything other than money.

    • Eliquis and others like this do not work for people who have FACTOR V LEIDEN as it thins on the wrong playlet level. So there is no viable option for people this seemingly rare blood disorder. Those with both genes are that much more at risk. 3000 times more likely to throw a DVT BLOOD CLOT then the normal person.

  3. I would like to know if the decision to discontinue Coumadin is based upon a safety factor or if it no longer cost effective
    for Bristol Meter to produce ir. Generics may have the same main ingredient as the name Brand but the binding factors can be different for each company producing the generic and therefore be absorbed in different parts of the GI tract therefore provide varying dosage absorption. This can result in varying dose absorption. Unfortunately larger companies dispensing pharmaceuticals, each time they purchase a drug, Generally purchase from the cheapest source. So, there is no guarantee that you are receiving the same dosage being absorbed in your body regardless of the dose identified on the bottle.

  4. I have been on both the generic and Coumadin. Coumadin works for me. I have Factor Five and have had many blood clots. This is an awful blow for me. The new meds, the expensive ones, make me very ill.

    • Carol this is a blow to me also. I cannot take generic only the name brand. I have Factor V and a protein C problem. I also have a inferior vena cava obstruction so coumadin has saved my life. I am going to talk with my hematologist this week. They dont want to put me on those other drugs. I feel bad for you

      • Generic warfarin is dangerous for those with factor V.. because the manufacturers are not FDA regulated. The tablets do not have the correct dose of warfarin I’m them. So keeping an even INR is impossible . I had DVTs and a pulmonary Embolism on generic warfarin. I also had a critical high INR that caused my kidney to bleed out. All I’m the same dose the whole time. Finally a doctor at UCSD told me about the problems with the binders put in generic warfarin causing trouble with the metabolism of warfarin and irregular INR. Since then the CHINESE GENERIC PHARMACEUTICALS ARE CURRENTLY UNDER INVESTIGATION FOR NOT PUTTING THE CORRECT DOSAGE OF MEDICINES IN MOST ALL THE GENERICS THEY MAKE. Making drugs like blood thinners dangerous to take as well as blood pressure medicines killing people because they were in to high of a dose or too low because the generic tablets don’t have consistent doses of the main drug in them. Also look up generic Valsartin you will see a current lawsuit and investigations for deaths caused by stage four lung cancer in patients because they put known carcinogens in the drugs they have been selling to America. Why our insurance companies are still insisting we take generic over name brand is amazing. They are not without fault or negligence because they all know the FDA DOES NOT REGULATE GENERIC DRUG MANUFACTURERS LIKE THEY DO NAME BRAND MANUFACTURERS. This known negligence will get these insurance companies sued in the deaths caused by these generic drugs. 500,000 cancer deaths are now known to be connected to Generic Valsartin blood pressure medicine. That’s just the beginning. CHINA MANUFACTURERS MOST ALL OF THE UNITED STATES GENERIC PHARMACEUTICALS!
        Beware !

  5. As a former pharmacist, and now retired pulmonary critical care physician I am most disappointed. I had an aortic valve replacement in 2006. My INR’s were quite variable with generic Warfarin, but stable with Trade name Coumadin – 4 mg daily. I was willing to pay the difference for the stability provided by Coumadin. I am most disappointed to learn Coumadin is being discontinued.

  6. my mom been on Coumadin for 12 years. This really sad how the Bristol-Myers care more for money. Then human life my mom has try Warfarin. Her blood will be a fine one month then the next month all over the place. Her doctor told her is cause Warfarin is made by different companies. He changed her to the Brand name and it help. The time we living there is no compassion. Come go Bristol-Myers please you guys are playing with human life.

  7. This is horrific!! My 99 year old mother who is very sensitive to medications is on Coumadin. Trying to find the next drug suitable for her will be trial and error not a risk we want to take!!!
    We were having some questions that only the manufacture would know they kept referring me to ask the pharmacist. This call was in March or April we had heard that it was being discontinued but she denied that would happen. Well here we are……

  8. My husband was on Coumadin for years. Then when he changed jobs they required him to take generic drugs and his INR went all over the place. We could not get it under control! His doctor requested that he only take Coumadin and NOT Warfarin! Once we went back to Coumedin he has been good ever since and that’s been at least 15 years now!!!

  9. This is unbelieveable i ve been on coumadin 22 years i have aortic valve and mitral valve replacement can t take generic all over the place very dangerous DR. said no generic ever should be a law against it.And just what i don t need getting upset .

  10. My husband has taken Coumadin for 20 yrs, Dr gave him generic warfarin at first and he had constant pain and body aches. Then was switched to Coumadin and no pain, it worked great with little INR variation. We are very disappointed to hear he will not have access to his med that has saved his life. Is this due to covid-19? Is there any pharmaceutical company that will pick up the manufacturing of coumidin going forward. From what I read,the newer blood thinners appear to be more hazardous to ones health.

  11. It is so sad that we are being placed in a dangerous position because warfarin is a dangerous drug for me because it makes my mouth and nose bleeds. COUMADIN has worked for me for 10 years 5 months and now manufacturer wants to stop making this medication. I had to fight to get my insurance to provide for COUMADIN and now no more. I am a US Army Disabled soldier that was stationed on a very toxic military base (Ft. McClellan, Alabama) and we had mystery illnesses for 28 years. February 3, 2010, I was hospitalized with deadly blood clots in the arteries and both of my legs had to be cut open from ankle to thigh. My surgeon came a hair of amputating both of my legs but Thank God, Jesus showed up and showed out. They found a tumor camouflaged like my organs and removed that and the woman with the issue of blood was no more. I was in the hospital for 38 days. When I arrived at the hospital walking and talking; my blood count was a 3 and I didn’t have enough oxygen to circulate through my entire body. I was in surgery for 13 1/2 hours. My doctor said if I hadn’t shown up at the hospital, I would have surely died within that night. I haven’t had no issues being on BRAND COUMADIN and now it is gone like that. I have been calling every pharmacy here in Los Angeles, CA trying to get prescriptions filled. So what did the manufacturer do with all those extra COUMADIN Pills that we all need? I am contacting them in the morning to find out and if they have any on hand, I am asking them to fill my prescriptions until my vascular doctor finds something else that works and don’t have serious complications. I am praying for all. God Bless!
