Mirena is an intrauterine device (IUD) that releases levonorgestrel, a chemical used to prevent pregnancy and treat heavy menstrual bleeding. The Food and Drug Administration (FDA) approved Mirena for use as a contraceptive in 2000, and approved Mirena to treat menstrual bleeding in 2009. Mirena is sold by Bayer, a German company with subsidiaries in the United States and across the world.
In April 2013, these claims were consolidated into Multi District Litigation (MDL) 2434 before the Honorable Cathy Siebel in the Southern District of New York. Suits are also pending in Bergen County Superior Court in New Jersey, being heard under New Jersey’s Multicounty Litigation process. (In Re: Mirena Litigation; Case No. 297)
