Plaintiffs who have requested the centralization of all federally-filed Mirena IUD lawsuits involving a serious brain injury called pseudotumor cerebri (aka idiopathic intracanial hypertension) will have a chance to make their case later this month.  According to an Order dated February 14th, the U.S. Judicial Panel on Multidistrict Litigation (JPML) will hear oral arguments on the matter during its March 30th Hearing Session in Phoenix, Arizona.

Second Bid for Centralization

In January, a group of Mirena brain injury plaintiffs filed a Motion with the JPML seeking transfer of the federal docket to a single judge in the U.S. District Court, Southern District of Mississippi, According to, the JPML denied a similar request in 2014, after finding that there were too few filings to justify centralization. However, plaintiffs’ latest motion indicates that at least 116 Mirena lawsuits involving pseudotumor cerebri/idiopathic intracanial hypertension are now pending in 17 different federal jurisdictions.

“Each of these actions assert virtually identical claims against the same defendants, the Bayer entities, for the same injury, the development of IH, caused by the same product, Mirena,” the motion stated. “While the number of filed cases is substantial, the filed cases represent only a small sample of the cases that are expected to be filed against Bayer by women alleging that Mirena LNG-IUS caused them to develop IH. This product has been used by more than 15 million women worldwide.”

Bayer Healthcare Pharmaceuticals, the manufacturer of the Mirena IUD, has voiced opposition to centralization.

What is Pseudotumor Cerebri?

Pseudotumor cerebri/ idiopathic intracanial hypertension is a condition that results from the over-accumulation of intracranial fluid in the brain. Symptoms mimic those of a brain tumor, and may include:

  • Migraine-like headaches that range from moderate to severe
  • Ringing in the ears
  • Nausea and Vomiting
  • Temporary or permanent blindness
  • Loss of peripheral vision
  • Double vision
  • Seeing flashing lights
  • Papilledema (swelling of the optic disk)
  • Neck, shoulder or back pain

Pseudotumor cerebri can be treated via lumbar puncture or brain shunt. However, if not recognized and treated in a timely manner, the condition can lead to life-long problems and permanent disability.

The Mirena IUD contains a synthetic form of progestin called levenorgestrel. Plaintiffs pursuing Mirena brain injury lawsuits assert that levenorgestrel in other birth control products has been linked to the development of pseudotumor cerebri. However, they claim that Bayer has failed to provide doctors and patients in U.S. with any warnings about this potential risk.
