What Is Elmiron?

Elmiron (also known as pentosan polysulfate sodium, or PPS) is a prescription medication used to treat interstitial cystitis, “or painful bladder syndrome.” Less frequently, Elmiron is used to treat osteoarthritis.

Elmiron Use Linked To Eye Damage

This medication has been linked to the development of retinal or pigmentary maculopathy, a serious eye disease. This disease may also be referred to as “central vision loss”.  Because this side-effect of Elmiron was only recently discovered, the condition is often misdiagnosed as macular degeneration or as other well-known macular disorders. Similar to macular degeneration, this condition alters pigment cells in the retina, changing the eye color while causing significant eye damage and vision loss.  

Symptoms of retinal or pigmentary maculopathy include:

  • Blurred Vision
  • Difficulty Reading
  • Difficulty Adapting To Dim Lighting
  • Dark Spots In The Center Of Vision
  • Straight Lines Appear Curved or Squiggly
  • Change In Eye Color
  • Muted, Less Vivid Colors

A 2017 study conducted by Emory Eye Center published in the American Academy of Ophthalmology examined the eyes of 34 participants for the development of a newly discovered eye condition called retinal or pigmentary maculopathy. The study found that every participant who tested positive for the disease had one thing in common, they all had been taking elmiron.

Janssen Knew About The Risk 

The manufacturer of Elmiron, Janssen Pharmaceuticals, Inc., knew about the dangerous side effects of the drug for more than 20 years. However, the company failed to warn patients about the risks associated with taking Elmiron. Patients paid Janssen billions of dollars for Elmiron and unknowingly risked developing permanent eye damage.
