Mirena perforation of the uterus is one of the most serious side effects association with the Mirena IUD birth control. Bayer, the manufacturer of Mirena, is facing lawsuits from dozens of women who were injured when their Mirena migrated from its original position, perforated their uterus, and required surgery to remove. If you suffered this complication, you may be eligible to file a Mirena lawsuit.

What is Mirena?

Mirena is an intra-uterine device (IUD), a type of implantable birth control. When the T-shaped implant is inserted into the uterus, it slowly releases the hormone levonorgestrel, which is more than 99% effective at preventing pregnancy for up to 5 years. Mirena is manufactured by Bayer HealthCare. It was approved by the FDA in 2000 to prevent pregnancy, and in 2009 to reduce heavy menstrual bleeding.

Mirena Perforation of the Uterus

Perforation of the uterus is a complication that occurs when Mirena punctures the uterine wall. Perforation is estimated to occur in about 1 out of 1,000 – 10,000 insertions. Perforation can also occur spontaneously when Mirena moves from its intended position and punctures the uterine wall. A gradual perforation can occur due to erosion in the uterine wall.

Researchers have found that uterine perforation is more likely to occur in women who have recently given birth, are breastfeeding, or have an atypical uterine shape (such as a retroverted uterus).

What are the risks?

If a perforated uterus is not diagnosed quickly, far more serious complications can occur. Swift diagnosis of a perforated uterus is essential to prevent further complications. If the retrieval threads are “missing,” an X-ray is usually recommended to locate Mirena. Without an X-ray, a doctor might assume that the IUD has simply fallen out. They could potentially fail to diagnose a uterine perforation.

Mirena can migrate outside the uterus. In the abdominal cavity, Mirena may puncture organs, intestines, or blood vessels. This can lead to intestinal blockages, life-threatening bleeding, and other complications.

Mirena may fail to protect against pregnancy. Pregnancy that occurs while the uterus is damaged or an IUD is in place can be life-threatening for the mother, and there is a potential risk of miscarriage or premature birth.

Damage to the uterus may cause permanent infertility. This risk is especially high if the uterus is scarred due to the perforation or surgical removal of Mirena.

Symptoms of Mirena Perforation of the Uterus

  • Unusual bleeding, which may be continuous
  • Pain in the abdomen or pelvic area
  • Unexplained fatigue
  • Infection
  • Missing threads that are normally used to retrieve Mirena
  • Pregnancy
