Texas Yaz LawsuitBeyaz blood clots are a severe, life-threatening side effect of this birth control pill. They can cause a pulmonary embolism, heart attack, stroke, or death. Evidence about the risk of Beyaz blood clots has been growing, and a massive FDA-funded study recently found that the risk of blood clots may be 75% higher for Beyaz than for other birth control pills that do not contain drospirenone.

April 10, 2012: The U.S. Food and Drug Administration (FDA) announced today that the agency will be updating the label on Beyaz and other birth control pills containing drospirenone, because “The FDA has concluded that drospirenone-containing birth control pills may be associated with a higher risk for blood clots than other progestin-containing pills.” The new labels will explicitly warn of the risk of Beyaz blood clots.

Beyaz is a once-daily, combination hormonal birth control pill that was approved by the U.S. Food and Drug Administration (FDA) in 2010 for the prevention of pregnancy. Beyaz is sold by Bayer HealthCare Pharmaceuticals, Inc., the same company that sells Yaz and Yasmin. Beyaz is essentially Yaz plus a folate B-vitamin dietary supplement.

The Beyaz regiment consists of “active” and “inactive” pills. Each active pill contains synthetic version of two hormones, estrogen and progestin. The synthetic estrogen in Beyaz is ethinyl estradiol (0.02-mg), and the synthetic progestin is drospirenone (3-mg). Each pill contains 0.451-mg of levomefolate calcium, which is a folate vitamin.

Why does Beyaz contain Folate?

Beyaz birth control pills contain folate to reduce the risk of certain birth defects. Though rare, sometimes women who are taking a birth control pill get pregnant. Doctors have known for many years that most neural tube defects (spina bifida, anencephaly, and more) could be prevented if women had enough folic acid in their systems. This is why many grains in the United States are fortified with folic acid. The FDA also recommends that all women of childbearing age take at least 0.4-mg of folic acid every day, even if they are not intending to become pregnant. The reason is because neural tube defects occur very early in pregnancy, so it is essential to have enough folic acid before the pregnancy occurs.

Beyaz Blood Clots

Beyaz blood clots are an extremely dangerous side effect of this birth control pill. The drospirenone in Beyaz increases a woman’s risk of developing a particularly dangerous form of blood clots: deep-vein blood clots that tend to form in the legs or pelvis. Unlike surface blood clots, the body cannot filter out deep-vein blood clots before they reach a major internal organ. Beyaz blood clots that get stuck in a major internal organ most often cause pulmonary embolisms, in which a blood clot causes lung tissue to die. Beyaz blood clots can also cause a heart attack, ischemic stroke, disability, organ failure, organ damage, or death.

The problem is that many women were unaware of this increased risk when they decided to switch to Beyaz, or another drospirenone-containing birth control pill. In fact, the FDA sent Bayer several warning letters (in 2003, 2008, and 2009) regarding “misleading” advertising for Yaz and Yasmin, two of the first drospirenone-containing birth control pills. The advertisements implied that the drugs were safer than older birth control pills, failed to communicate risk information, and misled women about what the drugs’ indications.

Beyaz Blood Clot Lawsuits

By the time Bayer ran a corrective advertising campaign, thousands of women had already been injured by these medications. Bayer now faces at least 11,000 lawsuits from women who were injured by birth control pills containing drospirenone. At least 50 of these lawsuits were filed by the family members of women who died from injuries caused by a birth control pill.

By law, pharmaceutical companies that sell medications have a duty to warn consumers about the risks of side effects. If a court finds that their failure to warn about side effects caused people to become injured, the pharmaceutical company could be forced to pay to compensate for the injuries.

Symptoms of a Beyaz Blood Clot

Beyaz blood clots are dangerous because they form deep inside the body, and they do not always cause symptoms until they get trapped in a major internal organ. If you ever suspect that you have a blood clot, call 911 immediately. Do not wait. A blood clot is an emergency situation that, if left untreated, can lead to death.

When Beyaz blood clots show initial symptoms, these may include:

  • Swelling in the affected area
  • Change in skin color, whiteness or redness
  • Pain in the affected area
  • Unusual warmth
  • Weakness in one part of the body
  • Loss of sensation
  • Paralysis of one part of the body, loss of function, tingling, numbness
