Mirena IUD Side Effects Spark Lawsuits

Posted on Aug 21, 2013 | 1 comment

Mirena IUD is a type of contraception approved by the FDA in 2000. More than 2 million American women and 15 million women worldwide currently use the popular birth control device, according to the National Law Journal. In July 2008, the FDA approved changes to Mirena’s labeling to reflect the complaints received by the federal agency. As of August 2012, the FDA received over 47,222 adverse event reports with regard to this intrauterine device.

What is Mirena?


Mirena is a flexible T-shaped plastic device that doctors insert into a woman’s uterus to provide up to five years of continuous birth control. It releases small amounts of progestin hormone to prevent pregnancy.

According to its own website, the main selling point of the IUD is convenience. Those who choose this form of contraception do not require commitment to a daily routine, nor must they make regular trips to the pharmacy. Once the device is in place, women can simply forget about it and go on with their daily lives and enjoy 99% rate of effectiveness in preventing pregnancy. Finally, Mirena is touted as a proven way “to treat heavy periods.”

Mirena side effects

RXList.com says the most common side effects of Mirena are: amenorrhea (lack of periods), inter-menstrual spotting, abdominal pain, ovarian cysts, headaches, acne and depression. The drug may also interfere with the use of insulin, warfarin and steroids. While no harmful effects on fetal development have been reported, small amounts of progestin do pass into the breast milk of nursing mothers, which will show up as steroids in the baby’s blood. The FDA cautions against use by women with a history of ectopic pregnancy or pelvic inflammation.

More serious Mirena side effects may include complications such as:

* Migration of the device

* Uterine perforation


*Pelvic inflammatory disease (PID)

*Organ damage

*Vaginal Hemorrhage


*Life-threatening ectopic pregnancy



*Emergency surgical removal

Device migration is the most commonly alleged side effect of Mirena in the growing number of lawsuits that have been filed. Such complaints commonly allege that the IUD moved from the top of the uterine cavity into the uterus or outside the uterus entirely. Uterine perforation or perforation of other internal organs is often a consequence IUD migration.

Women who develop signs of serious Mirena side effects should seek medical attention. Such indications include:

*Severe cramping or pelvic pain

*Dizziness and feeling faint

*Ongoing vaginal bleeding or discharge

*Pale skin, weakness, numbness, easy bruising

*Fever and chills

*Painful intercourse


*Back pain

*Abdominal pain

*Nausea / vomiting

  1. I had the Mirena put in August 2010, had spotting (4 plus mohtns), fatigue, hair loss,weight gain, bloating, high BP, and depression for 4 plus mohtns. With many calls to the gyn about why this was happening. They recommended that things would stabilize around 6 mohtns. I was coming home from work at noon to take naps, tearing up regularly and just plain felt crappy and crazy. I had no libido and broke up with my BF in November, citing that I was not in a good place and didn’t have the energy for the relationship. I had it removed in January 11 , my BP was the highest it had ever been during that apt. and I felt like I was having palpitations all the time. Since then, I am dealing with what I feel is abnormal fatigue, but all other symptoms seem to have abated.BP returned to normal almost instantly, it took about 4 mohtns for a regular cycle to start. A year for my hair to get back to normal, and aside from the fatigue, I don’t feel bloated or depressed. From discussions with friends (who had no issues) aside from some complaints about weight gain. I am of the opinion that this method works very well (as long as you don’t have the migrating issues) if your hormones are well balanced. So many things can cause hormonal imbalance (hence possibly why some say they are fine for years, then things take a turn, and they too feel crazy trying to identify what happened), mine was probably due to being in my 40 s (pre-peri-menopausal), and had a recent autoimmune issue with guttate psoriasis (due to a case of strep) when this was inserted.
