Upsher-Smith Laboratories and FDA are recalling one lot of Jantoven Warfarin Sodium, USP, 3mg Tablets -- an anticoagulant -- after a single bottle labeled as Jantoven Warfarin Sodium, USP, 3mg Tablets was found to contain tablets at a higher 10mg strength.
To date, the company has identified no additional mislabeled bottles.
The recalled lot is numbered as #284081, with an expiration date of September 2012. The product lot was distributed to wholesalers, retail chains and independent pharmacies throughout the United States. The primary risk of substituting 10mg warfarin for 3mg warfarin is overdosing more than 3 times the labeled amount which leads to excessive anticoagulation that could be expected to result in life-threatening hemorrhage in patients.
The two Jantoven tablets can be readily identified by color: the 3mg tablet is tan and the 10mg tablet is white. In addition, the 3mg tablet is imprinted with the letters WRF, a line, and the number 3 below the line. The reverse side of the 3mg tablet carries the number 832. The 10mg tablet is imprinted with the letters WRF, a line, and the number 10 below the line. The reverse side of the 10mg tablet carries the number 832.
