Mirena IUD Lawsuits

Mirena Lawsuit – What is Mirena?

Mirena is an intrauterine device (IUD) that is currently the most prescribed IUD in the US. Mirena works by thickening the cervical mucus and thinning the uterine lining, making it nearly impossible for sperm to reach an unfertilized egg, or for a fertilized egg to implant in the uterus. As soon as Mirena is placed in your uterus, it starts releasing the hormone levonorgestrel into your uterus to provide continuous birth control for up to 5 years. Mirena is popular among women who have children and aren’t sure if they want more and among women requiring treatment for endometriosis, polycystic ovary syndrome, or heavy periods. Though effective, the IUD has been shown to cause dangerous health complications.

Pseudotumor Cerebri:

Psuedotumor cerebri develops when the pressure inside the cranium increases without an apparent reason. The symptoms of psuedotumor cerebri mimic those of a brain tumor, but no tumor is present. The increased pressure from psuedotumor cerebri can create swelling of the optic nerve, which if left untreated, can cause permanent vision loss. Psuedotumor cerebri is most often found in obese women of child-bearing age, but has lately been associated with Mirena use.


Papilledema is an opthalmological condition where the optic disc swells due to increased intracranial pressure. This swelling damages the nerves of the eye and is secondary to psuedotumor cerebri.

Symptoms of Mirena IUD Side Effects:

There are many early warning signs of pseudotumor cerebri and papilledema. If symptoms are caught early enough, the effects might be reversible. Do not ignore the following warning signs if you are using the Mirena IUD.

  • Headaches that may originate behind your eyes
  • Hearing ringing or heartbeat noises
  • Nausea or vomiting
  • Dizziness or vertigo
  • Blurred or dimmed vision
  • Brief episodes of blindness, lasting only a few seconds and affecting one or both eyes
  • Difficulty seeing to the side
  • Double vision
  • Seeing light flashes
  • Neck, shoulder or back pain

Notify your doctor immediately if you are suffering from any of the above side effects. Permanent vision loss is possible if not treated soon enough.

Discovering and Treating Mirena IUD Side Effects:

The Mirena IUD should be removed as soon as possible is adverse side effects are suspected. Pseudotrumor cerebri is a rare diagnosis and is not initially considered by most treating physicians. Multiple test are usually required before arriving at a diagnosis of pseudotumor cerebri. Treatment for pseudotumor cerebri includes weight loss, medications, and surgery.

Test for Pseudotumor Cerebri:

  • Spinal Tap (Lumbar Puncture)
  • Eye Exams
  • Brain Imaging

Medications for Pseudotumor Cerebri:

  • Migraine Medications
  • Glaucoma Drugs
  • Diuretics

Surgeries for Pseudotumor Cerebri:

  • Spinal Fluid Shunt
  • Optic Nerve Sheath Fenestration

Failure to Warn of Mirena Side Effects:

The Mirena advertisements claim that the IUD releases a steady stream of low-dose hormones for up to five years, however several studies have shown that circulating levels of the active hormone Levonorgestrel can be very high. The levels can sometimes be equivalent to two oral tablets. Warnings of idiopathic intracranial hypertension, or psuedotumor cerebri, have been placed on Norplant, a similar long-lasting contraceptive also manufactured by Bayer. The packaging of Mirena warns that Mirena should be used with caution in patients who have “Migraine, focal migraine with asymmetrical visual loss or other symptoms indicating transient cerebral ischemia.” The warnings also indicate that for women who experience these symptoms, removal should be considered but is not outright advised. Lawsuits filed against Bayer claim that the manufacturer has a responsibility to more appropriately warn women and their healthcare providers of the possibilities of psuedotumor cerebri.
