The makers of Yaz and Yasmine are being questioned after a study found it had double the risk of other brands for strokes and blood clots.
The study from the British Medical Journal found an increased risk of clots are due to the chemical drospirenone which is unique to Bayer's Yasmine pills.
Twenty-five women from California have joined a lawsuit against Bayer, and hundreds of women from other states are joining the case.
Although Yaz is being scrutinized, doctors warn all birth control pills carry a risk for blood clots and strokes.
"It appears as though there is a higher risk with Yasmine compared to the others," Dr. Ravi Patel said. "But it doesn't mean the others don't have a risk. the others may have a four-fold risk, this may have a six-fold risk compared to a normal individual of getting blood clots if they are not taking birth control or hormonal replacements of any kind."
Dr. Patel says the key is to watch for symptoms like unusual chest pain, shortness of breath, cough, pain in your legs--particularly your calves--and pain associated with inflamed veins.
He says if patients have any of these issues, they should seek immediate attention. Dr. Patel says all birth control pills carry a risk for blood clots and other diseases and disorders.
"Hormonal replacement increases the risk of breast cancer, ovarian cancer and uterine cancer," Dr. Patel explained.
However, for many people, the pill is safe.
Alma Linda Duran says the warnings were enough to keep her from taking any brand of birth control pills.
"Why go through that and risk having strokes?" Duran questioned.
However, Renee Lopez says any medicine carries risks, and users should be aware of side effects.
"There's side effects to everything that you take," Lopez said. "So it doesn't whether you take vitamins or over the counter, there's always something that could affect it."
17 News reached out to Bayer for comment, but the company's spokesman didn't return the call.
