Bayer sued over birth control Yaz's risks
By William Ehart
After 13 hours of intensifying pain, two trips to the emergency room and two CT scans, doctors finally found what was ailing Lottie Green.
In her left lung, the pulmonologist told her, was the largest blood clot they had ever seen and there were others in her right lung as well, she said.
Soon after the 41-year-old Bethesda, Md., resident was released from a hospital last month, Ms. Green joined hundreds of other women in lawsuits against Germany's Bayer AG, the maker of the popular oral contraceptive Yaz.
Her attorneys say thousands more lawsuits are forthcoming after the British Medical Journal in August published a study that found higher risks of clots, heart attacks and strokes with Yaz and its predecessor, Yasmin, compared with other contraceptives.
Bayer and the U.S. Food and Drug Administration cite other studies - Bayer funded two of them - that reported no increased cardiovascular risk for the company's products compared with others. All oral contraceptives' users are at higher risk of cardiovascular side effects than the general population - as the products' labels warn.
