Texas Yaz LawsuitThousands of women have reported life-threatening Yaz side effects. Yaz contains a controversial ingredient called drospirenone, which may increase a woman’s risk of developing blood clots by 75%. If a blood clot becomes trapped in a major internal organ, it can cause a heart attack, stoke, pulmonary embolism, severe organ damage, organ failure, permanent disability, or death.

Yaz is a birth control pill that contains a combination of two hormones:

  • 3-mg drospirenone (synthetic progestin)
  • 0.02-mg ethinyl estradiol (synthetic estrogen)

Yaz is the first birth control pill to contain drospirenone, a new ingredient that was invented by the pharmaceutical company Berlex Laboratories (which later become Bayer HealthCare Pharmaceuticals, Inc.). The U.S. Food and Drug Administration (FDA) approved Yaz in 2006 to prevent pregnancy, reduce mild acne, and treat Premenstrual Dysphoric Disorder (PMDD).

Yaz is a once-daily contraceptive that consists of 24 “active” pills and 4 “inactive” pills. When taken as directed, it is more than 99% effective at preventing pregnancy. It works by inhibiting ovulation and making changes to cervical mucous and the uterine lining, which makes it difficult for an egg to implant.

Yaz and Drospirenone

Yaz contains drospirenone, a recently-developed type of synthetic progestin (a female reproductive hormone that inhibits ovulation). Drospirenone is sometimes referred to as “fourth generation” birth control, because it is newer than older progestin, such as norgestrel, levonorgestrel, and norethindrone. Because these medications have been used for decades, they are widely-known to slightly increase a woman’s risk of developing a blood clot. With older progestin, the risk is approximately 6 per 10,000 women. With drospirenone, the risk is approximately 10 per 10,000.

In September 2011, the FDA warned that drospirenone increased a woman’s risk of developing a blood clot by 75%. This evidence was based on a study of more than 800,000 women, and followed on the heels of several other studies that also found that Yaz side effects included an increased risk of developing blood clots.

Yaz and Blood Clots

One major side effect of Yaz is blood clots. When you used Yaz, you may not have realized that blood clots can be life-threatening or deadly. Yaz increases the amount of potassium in a woman’s bloodstream, which can increase her risk of developing a condition known as Deep Vein Thrombosis (DVT). When DVT occurs, blood clots form in vessels deep inside the body. They most commonly form in the lower legs, but can also form in the thighs, pelvic area, upper arm, and other parts of the body. These blood clots are different from surface blood clots in the legs (such as varicose veins). If blood pressure builds up behind a blood clot, it can break loose and start to move in the bloodstream. Now called an embolism, this blood clot will continue to travel until the blood vessels become too narrow, usually in the lungs, brain, or heart. When this Yaz side effect occurs, a woman suffers a pulmonary embolism, ischemic stroke, or heart attack. In the worst case scenario, the tissue damage can cause organ failure and death.

Yaz Side Effects

The most serious Yaz side effect is death. Bayer is facing at least 50 Yaz lawsuits brought by family members of women who died after using Yaz. In total, Bayer faces more than 11,000 lawsuits for side effects of its medications. If you have suffered any of the following Yaz side effects, you may be entitled to compensation if you file a Yaz lawsuit.

  • Depression
  • Blood clots
  • Deep vein thrombosis (DVT)
  • Venous thromboembolism (VTE)
  • Pulmonary embolism
  • Heart attack (myocardial infarction)
  • Stroke
  • Gallbladder disease
  • Pancreatitis
  • Hyperkalemia (toxic high levels of potassium)
  • Irregular heartbeat (heart arrhythmia)
  • Psychological trauma
  • Death
