Elmiron is the only oral medication approved by the U.S. Food and Drug Administration to treat interstitial cystitis, a painful bladder condition affecting mostly women. In recent years, studies have found an association between long-term Elmiron use and a serious eye condition known as pigmentary maculopathy. While there are other types of maculopathies, such as macular degeneration, pigmentary maculopathy (also known as PPS maculopathy) is uniquely associated with Elmiron. 

In June 2020, manufacturer Janssen Pharmaceuticals added a warning regarding the risk of pigmentary maculopathy. 

Elmiron is also associated with a wide range of other side effects.
