Mirena is an FDA-approved hormonal intrauterine device (IUD) used as a contraceptive and to treat heavy menstruation. It lasts up to seven years and is over 99% effective at preventing pregnancy. While generally safe, there are possible complications that can be serious.
One of the most important complications to be aware of is IUD movement or expulsion. When a Mirena IUD migrates, it can puncture the uterus or cause damage to other organs. Thousands of lawsuits have been filed against Bayer, with some women needing multiple surgeries after the IUD migrated to the abdominal cavity.
How Common Is IUD Migration and Expulsion?
IUD migration refers to the IUD moving outside its proper position. Expulsion happens when the IUD falls out. While these complications are uncommon, the risk is higher than you may think.
One study found the overall risk of IUD expulsion is 5% at five years, while the risk of uterine perforation is 0.6% at five years. Other studies place the IUD expulsion risk at 3-6% for hormonal IUDs or even higher. The American College of Obstetricians and Gynecologists estimates an expulsion rate of 2-10% during the first year.
It’s estimated that uterine perforation happens to one out of every 1,000 women with an IUD. While rarer, the IUD may pass through the outer lining and cause damage to nearby organs and blood vessels.
Why Would a Mirena IUD Move Out of Place?
Many factors can cause an IUD to move out of place, migrate, or even fall out. The positioning, size, and shape of the uterus can be a factor in how the body responds to the device.
You may be at a higher risk of IUD movement if:
- You have a tilted uterus
- You have a small uterine cavity
- The IUD was not inserted properly
- Your IUD was inserted soon after birth, especially vaginal birth
- You are breastfeeding
- You experience very strong menstrual cramps
- You are under 20 years old
- You use a menstrual cup
- You have uterine fibroids
An IUD is most likely to move within three months of insertion and while you are menstruating.
Signs Your Mirena IUD Has Moved or Migrated
If you suspect your IUD has shifted out of place, start by checking for the IUD strings. The thin strings of the IUD are usually one to two inches long and hang down from the uterus and cervix into the vagina.
If you cannot locate the strings, it’s very possible the strings were pulled into the uterine cavity.
Being unable to feel the strings can be a sign your IUD has moved if you experience any of the following symptoms:
- Excessive cramping
- Bleeding when you are not on your period
- Heavier period bleeding
- Pain in the lower abdomen
- Discomfort or pain during sex
- Feeling the IUD during sex
If you can feel the strings but they seem longer or shorter than usual, it may be because the IUD has moved. You should not feel hard plastic protruding from the cervix. If you feel the bottom of the IUD, it’s a clear sign the IUD placement is not correct.
If your Mirena IUD has fallen out or even been removed by a doctor, you may experience symptoms collectively known as the “Mirena crash.” This includes flu-like symptoms, fatigue, nausea, mood swings, depression, and pain during intercourse.
What To Do if You Are Injured by a Displaced IUD
Thousands of women have suffered injuries caused by IUD movement and perforation. The most serious consequences can include unwanted pregnancy, life-threatening infection, surgery, and chronic pain.
It’s a good idea to consult with an experienced personal injury lawyer to discuss your options. You may have a case related to a defective medical device or even medical malpractice if a physician’s negligence during insertion or removal caused your injury.
These cases are notoriously complex. Skilled personal injury lawyers have extensive experience handling cases involving medical negligence, medical devices, and product liability.
