“Over the past decade, thousands of women have either already filed or are seeking to file lawsuits against Bayer Pharmaceuticals over Mirena. These Mirena IUD lawsuits claim that the product causes serious physical harm, including organ perforation and intracranial hypertension (fluid buildup near the skull). Additionally, those suing believe that Bayer not only failed to adequately warn customers as to the risks associated with Mirena, but they used deceptive advertising practices to garner sales.
Bayer denied responsibility, saying the issues were caused by other factors, such as obesity, or that it previously warned that perforation could occur during insertion and that the plaintiffs understood the risks beforehand.
There was a multidistrict lawsuit (MDL) in New Jersey that was concluded in 2021. Two MDLs were also created in New York. While litigation is still ongoing, most of those cases were dismissed by 2018. In March 2022, Bayer also became the subject of a class action lawsuit in California.”
“In 2017, Bayer offered a $12.2 million settlement for organ perforation, which they estimated would include 4800 plaintiffs. Those cases settled in 2018. The California class action suit is still pending.
A class action suit was filed in California in March 2022, alleging that Mirena caused breast cancer in some users. This case is still ongoing.”
