Women Should Take Safest Birth-Control Pill, Researchers Say
By Andrea Gerlin
Aug. 14 (Bloomberg) -- Doctors should prescribe the birth- control pills that are the least likely to cause blood clots, according to a study of more than 3,000 women published today in the British Medical Journal.
Oral contraceptives containing levonorgestrel and a low dose of estrogen, such as Bayer AG’s Microgynon 30, were associated with the lowest risk of blood clots in the leg or lungs, researchers at Leiden University Medical Center in the Netherlands found. Birth-control pills containing desogestrel, cyproterone acetate or drospirenone carried about 1.5 to 2 times the risk of clots, they found....
Bayer’s Yasmin, Yaz and Yasminelle contain drospirenone. The three drugs brought in $1.86 billion for Bayer in the first quarter, and Yasmin and Yaz are the two biggest-selling contraceptives worldwide, according to IMS Health.
“We have not seen the data and can’t comment on it at this point in time and soon as we have seen it, we can evaluate it,” Bayer spokeswomen Friederike Lorenzen said in an interview yesterday. “Patient safety is of utmost importance for us.”
