Heart Disease Home > Generic Coumadin

There are currently several generic Coumadin products available on the market. These generic tablets are available in nine different strengths, just like the brand-name version. It is recommended that your healthcare provider monitor you more closely if you switch between different warfarin products, including switching from brand-name to generic versions (or vice versa), or even switching between different generics.

Is a Generic Version of Coumadin Available?

Coumadin® (warfarin sodium) is a prescription anticoagulant medication used to prevent and treat blood clots. It is known as a "narrow therapeutic index" medication, which means that there is little difference between the effective dosing range and the toxic dosing range. Special care must be taken when using generic versions of such medications.
Coumadin is manufactured by Bristol-Myers Squibb Company. The patents for the drug have long expired, and generic Coumadin is now available.

Strengths of Generic Coumadin

Just like brand-name version, generic Coumadin comes in the following strengths:
  • Warfarin 1 mg
  • Warfarin 2 mg
  • Warfarin 2.5 mg
  • Warfarin 3 mg
  • Warfarin 4 mg
  • Warfarin 5 mg
  • Warfarin 6 mg
  • Warfarin 7.5 mg
  • Warfarin 10 mg.
A generic form of injectable Coumadin is not available, probably because this product is used so rarely.

Who Makes Generic Coumadin?

Generic Coumadin is made by many different manufacturers, such as:
  • Barr Pharmaceuticals, Inc.
  • Sandoz
  • Upsher-Smith Laboratories, Inc.
  • Zydus Pharmaceuticals.
While most generic Coumadin products are sold under the name "warfarin sodium," one manufacturer (Upsher-Smith) has chosen to give its generic version a different, brand-like name (Jantoven®).
