Yaz Study Links Birth Control Pill to Irritable Bowel Syndrome Side Effects

According to a recent study, women who take drospirenone-containing birth control pills like Yaz may have a significantly increased risk of developing irritable bowel syndrome (IBS). The British Columbia study observed 939,281 women averaging 29 years of age and 247 days of oral contraceptive use. According to researchers, the annualized incidence for IBS with drospirenone (1083 women) was 224% higher than with women who used levonorgestrel (483 women). The study, released February 1, 2012, by the University of British Columbia, found that the use of oral contraceptives containing drospirenone greatly increases a woman’s risk of suffering from IBS, but research linking these birth control pills to serious side effects is not new.

In June 2012, the New England Journal of Medicine published a study in which ethinyl estradiol – an ingredient in both Yaz and Yasmin birth control pills – was associated with an increased risk of myocardial infarction and thrombotic stroke. Researchers found that the risk of these life-threatening conditions increased by a factor of 0.9 to 1.7 among women who took oral contraceptives that included ethinyl estradiol at a dose of 20 micrograms. Previously, the FDA issued warnings regarding Yaz and Yasmin in 2003, 2008 and 2009, alerting consumers and doctors about the potential link between the birth control pills and serious heart and health problems. Since their approval in 2001 and 2006 respectively, Bayer’s Yasmin and Yaz have been connected to side effects like deep vein thrombosis, heart attack, pulmonary embolism, gallbladder disease and stroke.


As mounting research focuses on the potential dangers of drospirenone-containing oral contraceptives like Yaz and Yasmin, injury claims filed on behalf of affected women are being considered by Yaz attorneys across the country.
