Yaz birth control, manufactured by Bayer HealthCare Pharmaceuticals, was introduced to the United States market in 2006.  Each pill contains a combination of  progesterin and estrogen.  Yaz and Yasmin are different than other combination birth control pills in that both contain drospirenone,  a synthetic form of progestin.  The drospirenone works in combination with ethinyl estrodiol (EE), a type of estrogen found in other contraceptives. Unfortunately, side effects have been associated with both Yaz and Yasmin, serving as the basis for hundreds of Yasmin and Yaz lawsuits.  Yasmin and Yaz lawsuits include claims against Bayer for failure to warn users of these side effects and for failure to conduct adequate clinical trials.

Noteably, there are differences between Yaz and Yasmin.  Yasmin was approved by the FDA in 2001 and has a slightly higher EE level per pill than Yaz.

Yaz Side Effects

Among the side effects giving rise to Yaz lawsuits are:


  • Deep vein thrombosis
  • Gallbladder disease
  • Liver cancer
  • High blood pressure
  • Heart attack
  • Stroke
  • Blood clots formed in a blood vessel that blocks a second blood vessel

Some of the Yaz lawsuits filed around the country allege that women have

died as a result of certain Yaz side effects.   A recent study in the British Medical Journal found that oral contraceptives such as Yaz, which use drospirenone, have a higher likelihood than other oral contraceptives of causing dangerous thrombotic events.  The number of Yaz lawsuits continues to mount, as more women become aware of the connection between their symptoms and their use of Yaz.

Filing Yaz Lawsuits

A thorough investigation must be conducted before Yaz lawsuits are filed.   Depending on the evidence of whether a woman’s use of Yaz or Yasmin contributed to her injury, a Yaz lawsuit may or may not be appropriate.  Yaz lawsuits may seek compensation for medical expenses, loss of income, partial or permanent disability and/or pain and suffering.
