Birth control pills Yaz and Yasmin are being blamed in 23 deaths after they were suspected of causing blood clots leading to unexpected and sudden death.
Doctors and pharmacists have been included in documentation that is part of a class-action lawsuit against Bayer, the maker of the pills.
The pills include a new synthetic hormone that no other birth control has: Drospirone. It is called a "newer generation" birth control that reduces the symptoms associated with menstrual cycles, but it also increases the chance of getting blood clots.
In 2011, Canada Health issued a warning about Drospirone, saying that it increases blood clots. They collected documents from more than 600 women who had experienced adverse side effects.
More than 1,000 women are being represented by attorney Tony Merchant, who said that many adverse reactions and deaths are going unreported. He suggested that the manufacturer knew about the increased risk of adverse reactions.
Bayer was ordered to pay almost $1 billion to women in America who suffered adverse affects from Yaz or Yasmin, including blood clots that led to heart attacks and strokes. Women who suffered from gall bladder damage were awarded up to $3,000 each.
The FDA has warned Bayer several times about misleading advertising, and the law firm of Page Bradley is filing a class-action lawsuit claiming the manufacturer is still misrepresenting Yaz in ads.
The law firm said they are "disturbed by the idea that the makers of Yaz were more concerned about painting a pretty picture in their advertisements than they were about the safety and health of their customer."
Bayer is denying claims that it was aware of the pill's side effects and says customer's safety is its number one priority.
Trial for the 23 deaths will begin in Canada in September.
