A number of women have reported suffering a condition known as pseudotumor cerebri (PTC) after being implanted with the Mirena intrauterine device (IUD). Also referred to as idiopathic intracranial hypertension (IIH), this condition involves a buildup of fluid pressure on the brain, which can mimc symptoms of a brain tumor.

The Mirena injury attorneys at Saiontz & Kirk, P.A. have been reviewing potential claims for women who suffered migration or perforation injuries caused by the birth control implant for several years. We are also now evaluating the potential for Mirena pseudotumor cerebri lawsuits for women who have developed this serious and painful condition.

Symptoms of IIH/PTC from Mirena side effects may include:

  • Moderate to Severe Migraine-Like Headaches
  • Ringing In The Ears In Time To Your Pulse
  • Nausea and Vomiting
  • Moments of Vision Loss In One or both Eyes
  • Loss of Peripheral Vision
  • Double Vision
  • Flashing Lights
  • Neck, Shoulder or Back Pain

Pseudotumor cerebri is a known side effect of levonorgestrel, the active progestin emitted by Mirena IUD birth control implants to help prevent pregnancy.

Since at least the 1990s, studies have found that it binds with other hormone receptors that can increase the risk of hormonal side effects, one of which is IIH/PTC. In addition, when taken alone, as it is with Mirena, studies indicate that the progestin significantly decreases sex hormone binding globulin (SHBG), which works to regulate hormonal side effects as well, including prevention of IIH/PTC.

In birth control pills, when levonorgestrel is combined with estrogen, like ethinyl estradiol, the estrogen increases SHBG levels, working as a counterweight to levonorgestrel’s side effects. However, critics say that the Mirena, by introducing levonorgestrel into the body alone, not only lacks the counterweight to hormonal side effects, it may accelerate them.

Despite the known link between PTC/IIH and levonorgestrel, the Mirena warning label makes no mention of this condition or the related tumor symptoms.

If you or a loved one have been diagnosed with pseudotumor cerebri, idiopathic intracranial hypertension or related problems caused by a build of a fluid pressure on the brain while using Mirena, request a free consultation and claim evaluation.
