Coumadin Brand is Being Discontinued – Generic Warfarin is Still Available

The box of Coumadin-Warfarin sodium and the "Discontinuation of Coumadin"

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:

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.

I took Coumadin 5 for over 14 years. I had no problems. I had the INR do once a months. Unfortunately it was discontinued Even so that Warferin is more difficult to control it is much simpler to take even with the once a months blood test. Prodaxa has 3 dose and has to be taken 2 a day and the dose depends on the Cr.Cl measurment. Eliquis is twice a day and decrease it after 6 months. Xarelto is once a day and is 20 mg but it increses the bledding possibility. All three cost about $ 600.00 a year. Do you have any comments? Thank you. Gabor Somjen MD


Dear Dr. Somjen,

The direct-acting oral anticoagulants, such as Pradaxa, Eliquis, and Xarelto may have some advantages to Coumadin since they are given in fixed doses, do not require INR monitoring, have few drug interactions, do not require dietary restrictions and carry a lower risk of bleeding compared to Coumadin. As well, since these medications wear off faster than Coumadin, bleeding problems may not be as serious if they do occur. Also, studies have shown that these medications work as well as Coumadin.

However, despite these advantages, the biggest disadvantage is definitely the higher price. As well, Coumadin may be the preferred choice for patients with liver disease, decreased kidney function, as well as for mechanical heart valves and for certain clotting conditions.

Many people do well on Coumadin for many years without any problems. If someone has been stable on Coumadin, without bleeding problems and doesn’t mind getting INR tests, then there is not necessarily any advantage to change to one of the direct-acting oral anticoagulants.

Even though, brand name Coumadin has been discontinued, generic warfarin is available, and could be considered an option for those previously on Coumadin. Studies have shown that patients can safely and effectively switch between generic warfarin and brand name Coumadin.
