Israeli Study Ties Yaz, Yazmin to Blood Clots in Texas Patients

Oral birth control has long been associated with an elevated risk of blood clots. However, there appears to be an even greater risk of these clots in women using pills that contain drospirenone. Researchers in Israel have found more evidence that fourth-generation birth control pills carry a higher risk of dangerous blood clots and Dallas Yaz injury claims than older types of birth control pills.

330,000 Israeli women participated in the study conducted by Dr. Naomi Gronich and other researchers at the Technion-Israel Institute of Technology. Among the all birth control users who participated in the study, six of every 10,000 suffered a venous thromboembolism. Venous thromboembolisms are blood clots that form in the leg veins; in some cases, they can travel to the lungs and cause a pulmonary embolism.

However, some participants were at higher risk for developing these dangerous blood clots. Those who used birth control pills with the hormone drospirenone were 43 percent to 65 percent more likely than other birth control pill users to develop venous thromboembolisms. The risk among women taking birth control pills containing drospirenone was found to be eight to 10 clots per 10,000 women per year. The risk was greatest in women over age 25.

Drospirenone is found in the active ingredient in fourth generation birth control pills sold under brand names Yaz, Yasmin, Ocella, Beyaz and Safryal. These pills are designed to cause less weight gain, swelling and other side-effects than older generation birth control pills.

Last week, the U.S. Food and Drug Administration (FDA) released updated results of their own investigation into the link between drospirenone and blood clots. They estimated a risk of 10 cases of venous thromboembolisms per 10,000 women using the fourth generation pills per year.
