Levy Konigsberg LLP Files Elmiron Lawsuit for Failure to Warn of Serious Drug-Induced Eye Disease

benzene lawsuit

New Jersey, June 9, 2020 – Levy Konigsberg LLP and Napoli Shkolnik PLLC have filed a products liability lawsuit in the Superior Court of New Jersey, Middlesex County, against the manufacturers of Elmiron, a prescription drug used to treat interstitial cystitis (bladder pain), for failing to warn plaintiff Valerie Hull of the risks of retinal damage. Mrs. Hull is represented by Corey Stern of Levy Konigsberg LLP and Hunter Shkolnik of Napoli Shkolnik PLLC. The complaint names Janssen Pharmaceuticals and several other Johnson & Johnson and Teva Pharmaceuticals entities as defendants who manufactured, marketed, and distributed the drug.

Mrs. Hull used Elmiron (pentosan polysulfate sodium) from approximately 2001 until 2018, and is considered to be “patient zero” in a 2018 Emory Eye Center study. While under the care of ophthalmologist Nieraj Jain and after undergoing a series of vision exams, Dr. Jain recommended that Mrs. Hull participate in a case study. Five other patients who were displaying similar eye issues were also added to the study. Each patient was being treated for interstitial cystitis with the drug Elmiron. Researchers found a new eye disease, retinal maculopathy, in all six patients.

Retinal maculopathy is a pathological disease of the macula (a small spot in the retina that is associated with highly sensitive, accurate vision). The pigment cells within the retina change color and can cause significant eye dysfunction. Other studies since the Emory Eye Center study have found that Elmiron may lead to an increased risk of retinal maculopathy, often diagnosed as retinal pigmentary maculopathy, pattern dystrophy, or age-related macular degeneration. In a Kaiser study, 24% of patients showed drug-induced retinal maculopathy. In an IC Network survey of 1,604 Elmiron patients, almost 54% had retinal disease.

Patients who have used Elmiron should be routinely screened by an optometrist or ophthalmologist for retinal damage.

Common symptoms of eye damage associated with retinal maculopathy include:

  • Blurred vision;
  • Central vision loss;
  • Poor light to dark adaptation;
  • Difficulty reading;
  • Dark spots; and
  • Other vision irregularities.
