U.S. District Judge Paul Engelmayer passed a summary judgment motion in a suit that alleged Mirena causes idiopathic intracranial hypertension, or IIH, further stating clearly in the multidistrict litigation, Bayer AG cannot be held responsible for causing IIH as the plaintiffs failed to show there was any admissible evidence proving Mirena could cause IIH.
The ruling was a result of a lack of proof against the pharmaceutical giant. Around 920 women allege Mirena use caused them to develop Idiopathic Intracranial Hypertension (IIH), which if left untreated, can cause headaches, vision problems and, in extreme cases, blindness. The judge said there is no scientific literature reviewed by medical organization, regulator or peer that has found Mirena, or any contraceptive, to be a cause of IIH.
As per the statement released by Bayer, "Judge Engelmayer's decision on summary judgment is a significant ruling that dismisses all cases pending in the MDL." Three multidistrict litigations have been set-up covering alleged side-effects of Mirena IUDs: MDL No. 2434 (In Re: Mirena IUD Products Liability Litigation (uterine perforation and migration) assigned to U.S. District Judge Cathy Seibel/and Judge Brian R. Martinotti of the Bergen County Superior Court; MDL No. 2767 (In Re:Mirena IUD Levonorgestrel-Related Products Liability Litigation (NO. II) ) in the United States District Courts; and NJ MCL No. 297 in New Jersey State Courts.
