Our Philadelphia Mirena injury lawyers are evaluating cases involving women with neurological injuries from Mirena IUDs. Mirena is a Bayer Pharmaceuticals intrauterine birth control device (IUD) designed to reduce a user’s pregnancy risk for up to five years.

Mirena works by releasing levonorgestrel, a synthetic form of the hormone progestin. The Mirena hormone is linked to serious neurological injuries alternately known as:

  • idiopathic intercranial hypertension (IIH)
  • intercranial hypertension (ICH)
  • pseudotumor cerebri (PTC)
  • false brain tumors

Mirena Neurological Injuries

Mirena and other levonorgestrel-releasing devices can result in serious and sometimes irreversible neurological damage. The synthetic hormone may cause an abnormal rise in blood pressure and increased level of cerebrospinal fluid inside a Mirena user’s brain. This can lead to increased pressure on the optic nerve and a dangerous neurological condition that mimics a brain tumor.

Despite its categorization as a “false” brain tumor, the condition may leave a patient with serious injuries, including:

  • permanent brain damage
  • permanent blindness
  • temporary vision loss in one or both eyes
  • blind spots
  • blurred vision
  • diplopia (double vision)
  • papilledema (optic nerve damage due to optic disc swelling)
  • severe and debilitating headaches
  • tinnitus (ringing in the ears that pulses with the patient’s heartbeat)

Patients may require one or more surgeries to alleviate some of the symptoms of eye and brain damage caused by Mirena.

Studies Linking Mirena Hormone with IIH / PTC / ICH

Several studies have demonstrated a link between use of levonorgestrel, the substance released by Mirena, and these neurological injuries. Physicians began to notice an increase in these injuries over two decades ago.

  • A study reported in the New England Journal of Medicine revealed a link between levonorgestrel and PTC / ICH as early as June 1995.
  • A U.S. National Institutes of Health (NIH) study reported in June 2015 found a “higher than expected number” of IIH / PTC injuries in Mirena IUD users.
  • Study results published in an April 2017 issue of Neuro-Ophthalmology demonstrated an increased risk of IIH / PTC in users of levonorgestrel IUDs such as Mirena. The risk in the two populations studied was approximately 0.18% and 0.15% in levonorgestrel IUD users as compared to 0.02% and 0.04% in non-users.

Mirena Neuro Injury Lawsuits

Philadelphia Mirena injury lawyers representing women suffering neurological brain / eye injuries after using Mirena may allege that the manufacturer:

  • knew or should have known of the increased risk of neurological injuries from Mirena
  • engaged in misleading / false advertising about the safety of Mirena
  • failed to adequately warn doctors and patients about the increased risk of neurological injuries from Mirena / levonorgestrel on package labels and patient information booklets
