Yaz, Yasmin and Ocella are oral birth contraceptives, made with a combination of two different types of hormones: estrogen and progestin. Unlike other contraceptives, Yasmin includes a common form of estrogen called ethinyl estradiol, as well as a unique, uncommon progestin known as drospirenone. Drospirenone can work against the body’s normal mechanism for regulating salt and water balance, which can lead to hyperkalemia in high risk patients, and can also result in many other potentially serious heart and health problems.
On May 31, 2011, the U.S. Food and Drug Administration (FDA) issued a safety announcement in regards to birth control pills that contain drospirenone. According to the FDA, several epidemiological studies have reported that the risk of blood clots for women who use birth control pills containing drospirenone is higher than that for women who use birth control pills containing the progestin levonorgestrel.
Not only has this warning been announced in the U.S., the European Medicines Agency also made the same announcement in May of 2011. Seven epidemiological studies were performed, evaluating the association between combined oral contraceptives (COCs) that contained drospirenone and venous thromboembolism (VTE). After review, the European Medicines Agency found that although the risk of VTE with any COC is small, the results from the studies still show that drospirenone-containing COCs are associated with a higher risk of VTE than levonorgestrel-containing COCs.
