Elmiron

What is ELMIRON?

(ELMIRON) This medication is used to treat pain/discomfort from a certain bladder disorder (interstitial cystitis). It may work by forming a layer on the bladder wall and protecting it from harmful/irritating substances in the urine. It is also a weak "blood thinner" and may increase the risk of bruising/bleeding (such as bleeding from the nose/gums).

How should I use ELMIRON?

Read the Medication Guide provided by your pharmacist before you start taking pentosan polysulfate sodium and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth at least 1 hour before or 2 hours after meals as directed by your doctor, usually 3 times daily. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not increase your dose or take this medication more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Tell your doctor if your condition worsens or does not improve after 3 months.
