The correlation between birth control pills and a higher rate of blood clots has long been documented. A study from Denmark suggests that non-oral forms of birth control – such as vaginal rings and skin patches – may also carry a risk of blood clots.
Most birth control pills carry a higher risk for blood clots, as does pregnancy itself. But numerous studies indicate that birth control pills containing the compound drospirenone – including Yasmin, Yaz, Ocella and Beyaz – carry up to three times the risk of blood clots compared to other birth control pills on the market. The U.S. Food and Drug Administration recently changed the labeling on the drospirenone contraceptives to reflect that.
Fox News reports that the study from University of Copenhagen, published in the British Medical Journal, analyzed information on more than 1.6 million women between ages 15 and 49 who were followed from 2001 to 2010.
Researchers found that a blood clot was twice as likely to appear in those who used a vaginal ring as in those who took birth control pills containing levonorgestrel, a synthetic hormone that studies have determined to be safer than drospirenone.
Patients should consult their doctors before making any changes in their medication. A consultation with a Beyaz lawyer is also important if there are significant injuries.
