Overview: Yaz, Yasmin and other oral contraceptives containing drospirenone are associated with irritable bowel syndrome (IBS), a study finds. The new generation of birth control pills, which were initially marketed as revolutionary, have already spurred a substantial amount of litigation claiming that the pills caused blood clots.
- A study in Current Drug Safety journal found that birth control pills containing drospirenone are associated with IBS
- Yaz, Yasmin and other similar oral contraceptives have been linked to blood clots, pulmonary embolism and gallbladder damage
- Bayer has paid over $400 million to settle lawsuits alleging that Yaz or Yasmin caused blood clots in the veins
Product: Yaz, Yasmin (Drospirenone and Ethinyl Estradiol)
Manufacturer: Bayer AG
Side Effects & Complications
- Blood Clots
- Pulmonary Embolism (PE)
- Deep Vein Thrombosis (DVT)
- Gallbladder Damage
- Heart Attacks
The study, which was published in the Current Drug Safety journal this February, gathered data from nearly 940,000 women between the ages of 18 and 46. Among this cohort, 3,050 cases of IBS were documented; 1,083 (0.77 percent) were linked to the use of drospirenone compared to 483 (0.46 percent) for levonorgestrel. Researchers stated that other types of oral contraceptives were not linked to irritable bowel syndrome.
The association between IBS and drospirenone birth control pills like Yaz or Yasmin appear small, but the link is there nonetheless. The authors of the study concluded that their research “found a positive association between drospirenone and a diagnosis of IBS that was not observed with other OCs (oral contraceptives)”.
Yaz, Yasmin Side Effects Lead to Lawsuits
Drospirenone-based birth control pills have also been associated with number of other side effects, including blood clots, pulmonary embolism and gallbladder damage; Bayer is currently facing 12,000 lawsuits alleging that Yaz or Yasmin caused such complications and that the company failed to warn about the risks. So far, the company has paid over $400 million to settle nearly 1,900 suits alleging the pills caused blood clots in the veins. If future cases are settlement for similar amounts, the Yaz, Yasmin litigation may cost Bayer as much as $1.2 billion.
