Pentosan polysulfate sodium (PPS) was initially approved by the U.S. Food and Drug Administration (FDA) to treat interstitial cystitis in 1996.

Pentosan polysulfate sodium (PPS) is primarily used to treat interstitial cystitis (IC) and painful bladder syndrome. It has also been explored for potential use in managing osteoarthritis, hemorrhagic cystitis, bladder pain syndrome, radiation-induced cystitis, blood clot prevention, deep vein thrombosis (DVT), pulmonary embolism (PE), vascular conditions, and inflammatory joint conditions. 

Pentosan polysulfate sodium is typically administered orally in capsules or tablets. However, in cases of bladder-related conditions like interstitial cystitis can also be delivered directly into the bladder through a catheter (intravesical administration). The choice of administration route depends on the specific medical condition and treatment plan.

Common side effects of  Pentosan polysulfate sodium may include gastrointestinal disturbances like nausea and diarrhea, headaches, and an unusual taste in the mouth. While serious side effects are rare, they can include bleeding disorders, liver damage, and allergic reactions. Serious bleeding events, although uncommon, may occur, and symptoms of liver damage can include jaundice, dark urine, and abdominal pain. Allergic reactions may manifest as rash, itching, swelling, severe dizziness, or difficulty breathing.
