Pentosan polysulfate (Pentosan polysulfate sodium) — Uses, Dosage, Side Effects & Safety

Drug class: Urogenital & Renal System

Overview

Pentosan polysulfate is a medication used primarily to relieve bladder pain and discomfort associated with interstitial cystitis (IC), also known as painful bladder syndrome. It works by forming a protective layer on the bladder wall, which helps prevent irritating substances in the urine from causing pain and inflammation. This medicine is not an antibiotic and does not cure infections, but it can significantly reduce symptoms such as urinary urgency, frequency, and pelvic pain. Most patients begin to notice improvement after several weeks of consistent use. Key points for patients: Take pentosan polysulfate exactly as prescribed, usually on an empty stomach. It may take up to 3–6 months to experience full benefits. Report any unusual vision changes or bleeding to your healthcare provider promptly.
