Yaz Increases Blood Clot Risk by 75%
Within the past year, popular birth control pills Yaz and Yasmin have come under fire from medical professionals and the Food and Drug Administration (FDA) for safety concerns. The FDA has now released a new study, which suggests the pills pose an even greater risk of blood clots than previously thought.
Yaz and Yasmin are considered fourth generation birth control pills because of a synthetic hormone they contain called drospirenone, which is similar to the natural female hormone progesterone and increases potassium levels in the blood. The pills have been touted by manufacturer Bayer as designer drugs that eliminate premenstrual symptoms (PMS). Of course, Bayer was forced to pull the advertisements claiming this back in 2009.
Based on recent studies about these birth control pills, medical experts believe drospirenone could be the culprit of increased blood clots seen in women taking these pills. The most recent studies evaluated data from more than 800,000 women ages 10 to 55 who took the pill over a period of six years. The results of the studies were alarming--women taking Yaz were 75 percent more likely to experience a blood clot than women taking birth control pills that do not contain drospirenone.
Despite the safety concerns with these pills, Yaz, Yasmin, and other drospirenone-containing birth control pills accounted for $1.6 billion in world-wide sales last year alone.
The FDA also analyzed data from studies conducted on the Ortho Evra patch and the Nuvaring vaginal ring. Results from those studies found that women using those forms of birth control experienced more complications than women using traditional or third generation birth control pills.
Although none of these products have been pulled off the market, the FDA will be meeting December 8th to determine the safety of these drugs. For now, consumer safety advocates are calling on the FDA to stop approving newer, less safe drugs when cheaper, safer generics are widely available on the market.
