A new type of contraceptive drugs doubled the risk of deadly blood clots compared to older versions of the contraceptive pill. This is the conclusion, researchers from the University of Copenhagen.
Experts warn women to opt for oral contraceptives "third generation", developed in the 1980s, that they should switch to a different type of medication. These conclusions were based on analysis of the health of millions of women living in Denmark. However, both types of drugs are still a relatively safe and may even reduce the risk of cancer.
It has long been observed that all types oral contraceptives Which take millions of Russian women to prevent pregnancy, increases the risk of developing blood clots in the deep veins of the legs, which in medicine is called venous thromboembolism . If one of these clots get to light, the matter may end in death.
Danish researchers analyzed the records of contraceptives and thromboembolism cases from 2001 to 2009, the millions of women aged 15 to 49 years. 4246 of them suffered venous thromboembolism the first time in this period. The risk of this complication grew three-fold among those who took the "old" oral contraceptives Levonorgestrel, and six times among those who adhered to the new types of drugs, the most popular of which is representative of the Yasmin.
"It is difficult not to notice that the combination of oral contraceptives with desogestrelom, gestodene, or drospirenone does not increase the risk of venous thromboembolism more than pills with levonorgestrel - commented results of the study Dr. Philip Hannaford of the University of Aberdeen. - Many physicians prefer to minimize risk and prescribe pills older generation. But it is very important after all not to exaggerate the danger - the risk is relatively small. "
