Mirena Users Have Filed Lawsuits for Brain Injuries

Consideration was given for the editing and publication of this post.

Mirena is a small plastic device used by women as a form of hormone progestin. The device is T-shaped and it is inserted into the uterus in order to release Levonorgestrel, a female hormone that makes it harder for a fertilized egg to attach to the uterus and even for the sperm to reach the uterus.

Basically, Mirena is different form of birth control. The device is placed into the uterus during an office visit and this is followed by monthly checks.

Possible serious side effects

It appears that despite its advantages, Mirena may have some serious side effects. If we take a look in the FDA database we can see that since January 1, 2004 there have been 76,840 adverse reports about this product. Since not many women report adverse events to the FDA, the real number is estimated to be around 700 000.

Many women say they dealt with brain injuries after they used Mirena, and they may be over 7 times more likely to develop pseudotumor cerebri and intracranial hypertension than evonorgestrel intrauterine systems. Back in 2014 a Nature article revealed how hormonal regulation of cerebrospinal fluid dynamics and pseudotumor cerebri syndrome are connected. Then, in April 2017 Nuero-Opthamology research claimed that Mirena users are 7 times as likely to develop pseudotumor cerebri.

The Idiopathic Intracranial Hypertension or Pseudotumor Cerebri

Pseudotumor cerebral is a syndrome of intracranial hypertension that arises suddenly, and it usually has no known cause. Alternatively, it can have an identified secondary cause such an event that affected the brain directly.

If you had a Mirena IUD implant, there is a list of symptoms that can show you if you have pseudotumor cerebri: nausea and vomiting, severe neck stiffness, visual changes, a whooshing noise in ears, depression, blindness, memory difficulties, numbness in hands, face or feet, migraines that usually begin behind ears and sharp in the legs, arms or back. If you have any of these, you should go see a doctor immediately. The most common ones are the whoosing noise, the visual changes and severe headaches.

Usually, this diagnosis is used as a last resort and doctors try to find other reasons for those symptoms. In order to get this diagnosis, you will need to be analysed by an ophthalmologist that will look for eye problems and a neurologist that will analyse the nervous system.

It has been discovered that women with Mirena can experience intracranial hypertension after only a few months of use.

Mirena lawsuits

More than one hundred lawsuits have been filed against Bayer. Since they all claim that Mirena caused them intracranial hypertension, the Federal Panel on Multidistrict Litigation granted a petition to bring together all these lawsuits into a single federal court.

Therefore, the Honorable Paul A. Engelmayer in the Southern District of New York will handle Mirena IUS Levonorgestrel-Related Products Liability Litigation. Until now, none of the mirena brain injury lawsuit cases have got in front of a jury and there have not been any settlements yet.
