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. Warfarin is actually the active ingredient in Coumadin. There are several generic warfarin products available. Generic drugs are supposed to have the same dosage, therapeutic effects, route of administration, side effects, and strength as the original drug. The U.S. Food and Drug Administration requires that all generic drugs be as safe and effective as brand-name drugs. However, when switching from Coumadin to a generic warfarin, it is important to get more frequent INR testing to ensure an appropriate target range.

      CanadaonlineHealth offers brand name Coumadin from New Zealand and Australia manufactured by Aspen pharmaceuticals, as well as, brand name Coumadin from Turkey, manufactured by Sanofi. These products are not generic medications. They are brand name, contain the same active ingredient (warfarin) and are considered equivalent to the brand name Coumadin, manufactured by Bristol Myers Squibb. However, they are not identical. Once again, when switching from one brand of Coumadin to another it is important to get more frequent INR testing to ensure the appropriate target range.

      Another alternative to Coumadin is the direct-acting oral anticoagulants, such as Pradaxa, Eliquis and Xarelto. However, there are certain conditions and indications where Coumadin (warfarin) is the preferred choice. Thus, it would be recommended to discuss these options with your son’s physician.

In any case, whenever a different brand or generic of warfarin is initiated, it is important to get more frequent INR testing to ensure an appropriate target range.

      Direct-acting oral anticoagulants, such as Pradaxa, Eliquis, and Xarelto may be another option to Coumadin, depending on the indication and your medical history.

      It would be recommended to discuss these alternatives with your physician.
