Elmiron Vision Loss Lawsuit

Connect with an attorney

Active case

Living with a chronic condition is challenging enough, but for some, unfortunately, medications can cause serious side effects. Elmiron®, a treatment for bladder pain and inflammation also known as pentosan polysulfate sodium (PPS), is the only FDA-approved oral medication available to treat the chronic bladder condition interstitial cystitis (IC). People taking Elmiron, for relief from the pain and discomfort caused by IC, have reported experiencing unexpected complications, including a newly discovered, progressive eye disease that may result in permanent vision loss.


July 8, 2020

Janssen Pharmaceuticals updated Elmiron’s label in June 2020 to warn of potential damage to the retina and irreversible vision loss that Elmiron could cause. According to the new label, the majority of damage and vision loss were reported in patients who had been taking Elmiron for at least three years, but cases involving patients who took Elmiron for a shorter time were also reported.

Elmiron (PPS) side effects

The Emory Eye Center in Atlanta released a study in November 2018 in which it found “a novel and possibly avoidable maculopathy associated with chronic exposure to PPS.” This newly discovered eye disease is often misdiagnosed as retinal pigmentary maculopathy, pattern dystrophy, or age-related macular degeneration.

The American Academy of Ophthalmology found similar results in a study it performed on patients at Kaiser Permanente in Northern California. Roughly a quarter of patients who reported significant use of Elmiron showed signs of eye damage, the study found.

Common signs of Elmiron®-associated eye damage/vision complications may include:

  • Difficulty adapting to changes in light
  • Blurred vision (often centrally in the patient's field of vision)
  • Dark spots in center of vision, blind spots or floaters
  • Straight lines appearing curved or squiggly
  • Muted, less vivid colors
  • Changes in the color of the eye

If you or a loved one took Elmiron and have been diagnosed with one of the following you may have a legal claim:

  • Retinal Maculopathy
  • Retinal Pigmentary Endothelium Injury (RPE)
  • Pigmentary Maculopathy
  • Pigmentation Maculopathy
  • Pigmentation Macular Degeneration
  • Dry Macular Degeneration

Elmiron background

Interstitial cystitis mostly affects women and causes chronic pain in the bladder and pelvis. The FDA approved Elmiron in 1996 to treat IC. It is the only FDA-approved oral medication to treat the condition, which is believed to affect millions of Americans.

Previously manufactured by Baker Norton Pharmaceuticals, the drug is currently owned and manufactured by Janssen Pharmaceuticals, Inc., a Johnson & Johnson subsidiary.

The drug’s label did not warn of potential permanent vision loss or eye damage until the update to the drug’s label was made in June 2020.
