The prescription drug Elmiron (pentosan polysulfate sodium) is the only FDA-approved medication used to treat interstitial cystitis, or bladder pain syndrome. However, new research indicates the side effects of Elmiron may be more severe than was previously understood.
The testing of pharmaceutical drugs usually happens over the course of 2 to 5 years. While this is usually sufficient to discover most of the side effects related to taking a drug, sometimes issues are not discovered until long after a medication has been on the market.
Despite the research from Dr. Nieraj Jain at the Emory Eye Center at the Emory School of Medicine in Atlanta, GA, and confirmation presented at the annual meeting of the American Academy of Ophthalmology in San Francisco, there have been no recalls of Elmiron.
