Upsher-Smith expands voluntary recall of Jantoven Warfarin Sodium, 3 mg Tablets

Upsher-Smith Laboratories, Inc., of Maple Grove, Minnesota is voluntarily expanding its previously announced recall of Jantoven® Warfarin Sodium, USP, 3 mg Tablets to include additional products that were packaged on the same packaging line between May 17, 2010 and November 17, 2010.  The company is initiating the recall as a precautionary measure after a single bottle labeled as Jantoven® Warfarin Sodium, USP, 3 mg Tablets was found by a retail pharmacy to contain tablets at a higher, 10 mg strength.

At Upsher-Smith, patient safety is of foremost concern.  The substitution of warfarin, or any other product, may lead to a change in the therapeutic effect of the intended drug.    

Consistent, continuous dosing of any product is necessary for optimal care for many ill patients.  Patients should check with their health care provider regarding the appropriateness of their current therapy prior to making any change.  

Upsher-Smith Laboratories is working cooperatively with the U.S. Food and Drug Administration to implement a nationwide recall as quickly and efficiently as possible.

The products affected were distributed to wholesalers, retail chains and independent pharmacies throughout the United States. The company is notifying its pharmacy customers and wholesalers, and arranging for the return of all recalled products.  These products were packaged at the Upsher-Smith plant in Plymouth, Minnesota.

Consumers and pharmacists can call 1-877-492-4791 for more information and to access product details, Monday-Friday between 8:00 a.m. and 5:00 p.m. (EST).

Any adverse reactions may be reported to the FDA's MedWatch Adverse Event Reporting program either online, by regular mail or by fax.
