CARMEL, Ind. -- More than 50 Indiana women have sued the makers of birth control pills Yaz, Yasmin and Ocella claiming that the drugs cause heart attacks and strokes.

Carmel attorney David Stewart represents most of the Indiana families who are suing Bayer, 6News' Tanya Spencer reported.

"We have clients that have numbness in the face, numbness down one side of their whole body." Stewart said.

The drugs’ packaging includes warnings of possible blood clots, heart attacks, strokes and gallbladder disease, but some attorneys taking part in a class-action lawsuit contend that’s not enough. They want "more adequate" warnings, or a recall.

Bayer released a statement to 6News that pointed out warning labels are on the products.

"The company is in the process of gathering information on these cases, but the complaints we have reviewed so far pertain to side effects that are warned about in the labeling of all oral contraceptives, including ours," the statement read.

Nearly 30 percent of women who take oral contraceptives take either Yaz or Yasmin.

"I use them quite frequently, especially for my practice, because I have patients with polycystic ovaries," said Dr. Marguerite Shepard. "The risk is definitely overblown."

Women with a family history of blood clots shouldn't take Yaz, Yasmin or other drugs that raise potassium levels.

Shepard thinks the risk of serious side effects is very low and that the potassium level is too miniscule to cause the damage that is alleged.

Stewart expects the Indiana lawsuits will become part of a class-action lawsuit that could take years to litigate.

Bayer officials said they will defend the company vigorously.
