Yasmin/YAZ Class Action

In March 2010, a class proceeding was commenced against Bayer Inc. on behalf of all persons in Ontario who used Yasmin® and YAZ® between the times these drugs were first made available in Canada (2004 and 2008 respectively) and November 30, 2011.

The claim alleges that both Yasmin® and YAZ® are associated with an increased risk of suffering various types of blood clots and gallbladder disease, compared to other available oral contraceptives.  The claim further alleges that the increased risk was known to Bayer Inc. and they failed to timely or adequately communicate the risk information to consumers and the medical community.
