Recall of Jantoven Warfarin Expanded to Other Upsher-Smith Drugs

A Jantoven Warfarin recall issued last week after the discovery of a mislabeled bottle, has been expanded to include other medications manufactured by Upsher-Smith Laboratories, including Amantadine, Amlodipine, Androxy, Baclofen, Bethanechol and Oxybutynin. 

The expanded Upsher-Smith drug recall was announced on February 18, adding additional medications that were labeled on the same packaging line between May 17 and November 17, 2010. The company has said that the expansion is a precautionary measure.

Taking the wrong pill could result in consumers suffering drug overdoses, unexpected side effects, severe injury and also means that the consumer did not get the medication they were prescribed. There have been no injuries or illnesses reported in connection to mislabeled Upsher-Smith drugs.
