Upsher-Smith Announces Nationwide Recall Of Jantoven Warfarin Sodium Tablets, 3mg, Due To Mislabeled Bottles

Upsher-Smith Laboratories, Inc. is voluntarily recalling one lot (lot #284081) of Jantoven Warfarin Sodium, USP, 3mg Tablets, an anticoagulant, or "blood thinning" medicine that prevents the formation of blood clots. The company is initiating the recall because a single bottle labeled as Jantoven Warfarin Sodium, USP, 3mg Tablets was found to contain tablets at a higher, 10mg strength before it was dispensed. To date, the company has identified no additional mislabeled bottles.

The primary risk of substituting 10mg warfarin for 3mg warfarin is that overdosing can lead to excessive anticoagulation which may result in life threatening bleeding.

Warfarin is sold in different strength tablets (1 mg, 2mg, 2.5mg, 3mg, 4mg, 5mg, 6mg, 7.5mg, and 10mg) and is available as the generic name warfarin and brand names Coumadin and Jantoven. This recall only involves a single lot of Jantoven Warfarin Sodium, USP, 3mg Tablets. No other brands or strengths of warfarin are involved in the recall.
