Warfarin Sodium Tablets (Jantoven), 3 mg: Recall - Mislabeled Bottles Containing Higher Dosage

AUDIENCE: Pharmacy, Family Practice, Consumer

Upsher-Smith Laboratories and FDA notified healthcare professionals of the recall of 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.

BACKGROUND: 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.

RECOMMENDATION: The two Jantoven tablets (see photo at link below) 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. Consumers and pharmacists can call the Upsher-Smith medical information line at 1-888-650-3789 for more information and to access product details, Monday-Friday between 8:00 a.m. and 5:00 p.m. (CST).

Upsher-Smith實驗室及FDA提醒醫護人員回收一批次的抗凝血劑Jantoven Warfarin Sodium, USP, 3 mg Tablets，因為發現其中一瓶包裝標示為Jantoven Warfarin Sodium, USP, 3 mg Tablets，但內含10 mg的藥品，至今，未發現有其他錯標產品。

回收的批號為284081，效期2012年9月，販售至全美的批發商、零售店及藥局，10 mg 錯標成3 mg的主要危險是超過3倍標示量可能導致過度抗凝血效果而造成致命性出血。

Jantoven兩種劑量藥品可以由顏色明確分辨，3 mg為棕色，10 mg為白色，另外，3 mg錠劑一字刻痕上印有WRF字樣，下印有數字3，另一面印有832，10 mg錠劑一字刻痕上印有WRF字樣，下印有數字10，另一面印有832，消費者及藥師可打Upsher-Smith的藥物諮詢專線詢問更多資訊。
