Pharmaceutical Basics Inc. of Denver recalled two lots of its antidepressant desipramine in late March because of a label mix-up. People taking the finn's desipramine were advised to examine their tablets for any marked with the name warfarin, a blood-thinner. The lots under recall are G873-01 and G685-08.
PBI made the desipramine for distribution by H.L. Moore of New Britain, Conn. Moore notified PBI on March 27 that it had discovered one bottle labeled 25 mg desipramine" that actually contained 5-mg warfarin tablets.
The warfarin, which can cause serious bleeding, is an uncoated pink tablet imprinted on one side with " -5-" and on the other side with 832" and the word "warfarin." Desipramine is a coated lavender tablet imprinted with the numbers "832" over "G254." Because the tablets look so different, a pharmacist filling a prescription would probably notice mislabeled tablets. Nevertheless, patients were advised to return their desipramine to the pharmacy if the prescription had been filled or refilled during the previous six months from Moore's 25-mg tablets, which they can find out from the pharmacist.
PBI telephoned Moore's 350 customers-pharmacies and physicians-to inform them of the mix-up. The only desipramine products under recall are those made by PBI for Moore's distribution. About six other manufacturers make the drug.
