Bayer Chastised For Bad Manufacturing Practices At YAZ Plant

It is not enough that their pills are dangerous—it now turns out that some of them may not even be effective. The FDA inspected Bayer’s Germany plant in March where drospirenone, the fourth-generation progestin, is created for Bayer’s top-selling YAZ and Yasmin birth control pills. Essentially, Bayer had been sampling their product and averaging the results, then delivering the averaged data to the FDA. Instead, Bayer should have been delivering the results of each sample of the product. Averaging increases the likelihood that the samples will pass efficacy muster.
