July 16, 2013 — Mirena lawsuits were centralized into a federal litigation against Bayer HealthCare in April. In just three months, at least 105 lawsuits have been transferred into the Multi-District Litigation #2434 in the U.S. District Court for the Southern District of New York before Judge Cathy Seibel.
All of the lawsuits allege that Mirena is defective and Bayer failed to warn about the risk that the IUD can spontaneously migrate and perforate the uterus. When this complication occurs, surgery is necessary to remove Mirena.
One of the newest plaintiffs in the litigation is Lourdes Gonzales, who was implanted with Mirena in Pittsburgh in 2009. Nearly two years later, she suffered a cervix perforation when Mirena spontaneously migrated. In July 2011, she required surgery to remove Mirena. She alleges that the surgery caused her to suffer pain and financial losses. She also alleges that she continues to suffer from permanent complications, including uterine scarring and an increased risk of placenta accreta.
Bayer is facing lawsuits for failing to warn about the risk of spontaneous migration, perforation of the uterus, and the risk of needing surgery to remove Mirena. The risk information for Mirena only warns about perforations that occur while Mirena is being inserted into the uterus. Some lawsuits also allege that Bayer does not adequately inform women about the risk of other complications, including ectopic pregnancy.
