Table of contents:

Elmiron generically known as Pentosan Polysulfate is a prescription medication commonly used to treat Interstitial Cystitis, a chronic condition that causes bladder pain and frequent urination. It may work by forming a layer on the bladder wall and protecting it from harmful/irritating substances in the urine.

Pentosan Polysulfate is an oral medication that works by forming a protective coating over the bladder wall, reducing inflammation and irritation. It helps to treat causes of inflammation in the bladder, causing symptoms such as painful urination, frequent urination, pelvic pain, and bladder pressure or discomfort.

Elmiron is the only FDA-approved oral drug specifically designed to treat this condition and has been available since 1996. It is also a weak "blood thinner" and may increase the risk of bruising/bleeding (such as bleeding from the nose/gums).

Uses and Dosage

Elmiron comes in the form of a Capsule to take by mouth at least 1 hour before or 2 hours after meals as directed by your doctor, usually 3 times daily. It should be taken with water at least 1 hour before meals or 2 hours after meals. Take Elmiron regularly to get the most benefit from it and to help you remember and keep it at the same time each day.

The typical dose of Elmiron is 100 mg by mouth 3 times per day with water, at least 1 hour before or 2 hours after meals. Do not increase your dose or take this medication more often or for longer than prescribed as your condition will not improve any faster and your risk of side effects will increase.
