Research News: Generic Drug Safety Labels Often Contain Incorrect Information

More than two-thirds of generic drugs carry safety warning labels different from those of their branded equivalents, according to a new study by researchers at the Regenstrief Institute. Researchers reviewed over 9,000 product labels for more than 1,500 drugs available on the FDA and National Library of Medicine online labeling information repository DailyMed. Of more than 1,040 drugs with more than one manufacturer’s label, 68% had discrepancies within their safety information. The researchers found that most of the generic showed relatively small differences, but 9% showed differences of more than 10 side effects, and other errors included out-of-date information, incomplete data and one that had information for the wrong drug. The study was published online in the journal Pharmacoepidemiology and Drug Safety and will be published in the print edition as well.
