The once widely-popular prescription contraceptive medication Yaz has been at the center of a growing number of lawsuits, as more than 4,000 individual and class action lawsuits have been filed against Yaz’s manufacturer, Bayer Pharmaceuticals, over alleged side effects suffered by women ages 14 and older who had been prescribed the contraceptive. The drug had also been prescribed as an acne treatment for some women.
Like all prescription medications, Yaz was subject to the same clinical trials and FDA approval, but it is difficult to determine the side effects of contraceptive drugs because they lack placebos in tests. For several years, women have reported serious and, in some cases, life-threatening side effects as a result of using Yaz. These side effects include gallbladder disease, heart attacks, strokes, pulmonary embolisms, deep vein thrombosis, and sudden death.
