Mirena Hormonal Intrauterine Device (IUD)

Mirena IUD Lawsuit


CASE UPDATE: Overview Update 

February 2019 - The Mirena cases are consolidated in the U.S. District Court for the Southern District of New York in front of Judge Paul A. Engelmayer.  Several months ago, Judge Engelmayer heard arguments from both the plaintiffs' and defense (Bayer) attorneys regarding their respective positions on the science in this case.  These arguments are of critical importance since the judge is determining what evidence will be allowed in the case. Unfortunately, on October 24, 2018, Judge Engelmayer ruled to exclude the testimony of all seven plaintiffs' experts.  In essence, he ruled that he did not believe that the plaintiffs' experts had enough scientific evidence to support the allegations that Mirena was causing the injuries claimed.  We obviously strongly disagree with his findings.  The plaintiffs' attorneys are working together to appeal his decision.

What is Mirena?

Mirena is a hormonal intrauterine device (IUD) inserted into the uterus for long-term pregnancy prevention. It is a T-shaped device a bit larger than a quarter. The device prevents pregnancy by stopping sperm before it reaches the uterus and fertilizes an egg. If used correctly, the chances of getting pregnant are less than 1%.

There are two types of IUDs. The first is copper based and does not release hormones. The second is a plastic device that releases a controlled dose of hormones; Mirena is such a device. Mirena releases a hormone called levonorgestrel. Mirena is designed to prevent pregnancy for up to five years and is one of the most common IUDs in the United States.

In the United States, more than two million women have used Mirena since the device was introduced in 2000. Since then, roughly 70,000 complaints about the dangerous side effects associated with the drug have been made to the U.S. Food & Drug Administration.

Lawsuits have been filed against Bayer Pharmaceuticals, the manufacturer of Mirena, by women across the country who allege that Bayer failed to adequately report or warn of the dangers associated with the drug-device combo. The lawsuits not only allege that dangers were understated by the manufacturer and hidden from consumers but also allege the devices were both defective and unreasonably dangerous.


Side Effects Associated with Mirena, Including Brain Injury

According to the manufacturer, the side effects of Mirena include:

  • Pain, bleeding or dizziness during and after placement
  • Expulsion
  • Missed menstrual periods
  • Changes in bleeding
  • Cysts on the ovary
  • Pelvic inflammatory disease (PID)
  • Life-threatening infection
  • Perforation


Injuries in a Mirena IUD Lawsuit

  • Idiopathic intracranial hypertension (IIH)
  • Pseudotumor cerebri (PTC)
  • Vision issues – blurred vision or blindness
  • Chronic headache
  • Balance issues

If you believe you have been injured by the Mirena IUD birth control device, please seek medical attention right away.


 If I’ve suffered from Idiopathic Intracranial Hypertension or Pseduotumor Cerebi, What are the Next Steps?

These side effects are dangerous and will more than likely require meeting with both a neurologist, who will monitor the nervous system and spinal cord and an ophthalmologist, who monitors potential eye problems. There are multiple treatment options, including surgery, but the treatment will depend on each individual’s condition and level of severity.
