More Clots with Newer Birth Control Pills
Some newer birth control pills may carry a higher risk of blood clots, a study finds. The study focused on pills that use the hormone drospirenone. It is found in Yaz, Yasmin and some other brands. There are also generic pills. Drospirenone is a form of progestin. Older pills used other forms. The newer pills have become popular because they are less likely to cause certain side effects. The new study was based on records for 330,000 women in Israel. Overall, there were 6 blood clots in veins each year for every 10,000 birth control pill users. The risk was higher for those who took pills containing drospirenone â about 8 to 10 clots per 10,000 women per year. Clots in veins are known as deep vein thrombosis. These clots can kill if they travel to the lungs. The Canadian Medical Association Journal published the study.
