Plaintiffs in Elmiron lawsuits accuse Janssen Pharmaceuticals of failing to properly warn the public about the risk of vision problems. Recent studies linked the interstitial cystitis (IC) drug, also known as pentosan polysulfate sodium (PPS), to ocular toxicity and irreversible vision damage.

Research presented at the American Academy of Ophthalmology in 2019 by Drs. Robin A. Vora, Amar P. Patel, and Ronald Melles revealed that patients taking Elmiron showed clear signs of toxicity.

“It’s unfortunate,” Vora said in an American Academy of Ophthalmology news release. “You have a patient with a chronic condition like interstitial cystitis, for which there is no cure and no effective treatment. They get put on these medications because it’s thought to have few side effects and few risks, and no one thinks about it again. And year after year, the number of pills they’re taking goes up and up.”

“We believe that our findings add strong support to the growing body of evidence that links long-term PPS use to the potential development of a toxic maculopathy.”

Drs. Robin A. Vora, Amar P. Patel, and Ronald Melles

In January 2020, Drs. Vora, Patel, and Melles published a follow-up study of 117 patients in Ophthalmology.

“We believe that our findings add strong support to the growing body of evidence that links long-term PPS use to the potential development of a toxic maculopathy,” the authors said.

The drug has been on the market since the late 1990s, and it is the only drug approved to treat pain associated with interstitial cystitis, or IC — a condition that affects millions of Americans each year. IC is more prevalent in women, and many use Elmiron long term to treat the disease.

Hundreds of thousands of people may have taken the drug and may have been exposed to the risk of potentially permanent vision damage.

Maculopathy and Pentosan Polysulfate Sodium

Elmiron’s current prescribing information provided by Janssen Pharmaceuticals lists the drug’s side effects and warnings but has no information about the risks of maculopathy, a type of disease that affects the macula, or other visual changes or conditions.

Starting in 2018, studies began to document irreversible vision problems associated with long-term use of Elmiron.

The macula is the backside of the retina. The retina senses light and sends a signal to the brain, allowing people to see. Retina damage affects a person’s vision. In the Western world, maculopathy is the most common cause of blindness.

Anatomy of an Eye
Elmiron may cause damage to a part of the retina called the macula, causing vision problems.

The type of maculopathy linked to Elmiron is called pigmentary maculopathy. According to studies, this type of maculopathy seems to be unique to Elmiron users.

If caught in its early stages, the damage may stop after taking medication. But in late stages, the disease can lead to permanent vision loss. So far, researchers have reported on one patient whose eye damage continued for years even after stopping Elmiron.

The most common visual symptoms reported in studies were difficulty reading and difficulty adapting to dim lighting.

Symptoms Associated with Elmiron Damage in Studies:
  • Areas of vision loss in the field of vision, paracentral scotoma
  • Difficult time adjusting to dim lighting or the dark
  • Having a hard time reading
  • Problems seeing objects that are close
  • Vision dimming
Timeline of Studies
  • May 2018
    Dr. William A. Pearce and colleagues at the Emory Eye Center published results of a case study of six adult patients who took pentosan polysulfate sodium for IC in Ophthalmology. They found chronic exposure to the drug caused unique pigmentary maculopathy — specifically, injury to the retinal pigment epithelium, a layer of cells that nourishes the retina.
  • April 2019
    Doctors at Emory Eye Center published an expanded study of 10 patients in the Journal of Urology. Researchers noted that patients with a history of IC who did not take pentosan polysulfate sodium did not have the unique form of pigmented maculopathy present in patients who took the drug. They recommended that patients with signs of damage stop taking Elmiron and patients without symptoms undergo an ophthalmic examination with retinal imaging.
  • October 2019
    Researchers at Kaiser Permanente found 140 patients who had taken about 5,000 pentosan polysulfate sodium pills over the course of 15 years. Of those patients, 91 agreed to be examined. Twenty-two out of those 91 patients had signs of toxicity. The toxicity was greater in patients who took more of the drug — 11 percent in patients taking 500 to 1,000 grams and 42 percent in patients taking 1,500 grams or more.
  • November 2019
    Dr. Neiraj Jain and colleagues published a cohort study of data from a large United States medical claims database from 2002 to 2016 in the British Journal of Ophthalmology. They followed data from two groups of pentosan polysulfate sodium users: one group of 3,012 at 5 years and the second group of 1,604 at 7 years. They found pentosan users had significantly increased odds of macular disease at 7 years.
  • November 2019
    Drs. Rachel M. Huckfeldt and Demetrios G. Vavvas published a case report in Ophthalmic Surgery, Lasers and Imaging Retina. They presented the case of a patient whose pentosan-associated maculopathy continued to get worse 6 years after stopping the medication.
  • January 2020
    Drs. Robin A. Vora, Amar P. Patel, and Ronald Melles looked at data for 117 patients with IC who took PPS and found 27 had definite signs of maculopathy. Those who took more than 1,500 g had the highest risk of toxicity. Authors said their findings provided “strong support” to previous studies that linked long-term use of Elmiron to toxic maculopathy.

Do I Qualify for an Elmiron Lawsuit?

Lawyers are accepting cases from people who took Elmiron for at least two years and suffered vision problems, especially if they were still using Elmiron from 2018 to present.

These vision problems must have started while taking Elmiron or within one year of stopping treatment. For example, if you stopped taking Elmiron in 2010 and got a diagnosis of an eye condition in 2011, you may qualify.

Injuries in lawsuits include:
  • Blurred vision
  • Degenerative maculopathy
  • Halo vision
  • Macular retinopathy
  • Macular/pattern dystrophy
  • Maculopathy
  • Metamorphopsia
  • Pigmentary maculopathy
  • Reduced night vision
  • Retinal pigment epithelium atrophy
  • Retinopathy
  • Scotoma
  • Unilateral or bilateral blindness
  • Vision impairment
  • Vision loss

What treatment did your medical provider recommend for your vision problems?
Bring any medications you’re currently taking for your vision problems. Your attorney will want to know if your vision problems have improved as a result of this treatment.

Connecticut Woman Files Elmiron Lawsuit for ‘Permanent Retinal Injury’

On March 26, 2020, Kimberly Pelczar filed a lawsuit against Teva Pharmaceuticals USA Inc. and Johnson & Johnson’s subsidiary Janssen Pharmaceuticals because of vision loss she claims resulted from Elmiron.

In 2005, Pelczar began taking Elmiron for IC. In 2015, she began to suffer eye problems. From 2015 to 2019, she saw medical providers for her visual symptoms.

In 2019, medical providers diagnosed her with permanent retinal injury and vision loss because of Elmiron toxicity.

The complaint said drugmakers failed to properly warn physicians and the public that Elmiron could cause vision problems and claims drugmakers actively hid the side effects from the public.
