What is ELMIRON® (pentosan polysulfate sodium)?

ELMIRON® is a prescription medication used to treat the bladder pain or discomfort associated with interstitial cystitis (IC). It is not known exactly how ELMIRON® works, but it is not a pain medication like aspirin or acetaminophen and therefore must be taken continuously for relief as prescribed by your doctor.
