What is Elmiron?

Elmiron (Pentosan Polysulfate Sodium) is a medication used to treat bladder pain and discomfort caused by cystitis, a disease which causes swelling and scarring of the bladder wall.

How does Elmiron work?

Elmiron is thought to work by forming a layer on the bladder wall which prevents it from harmful or irritating substances in the urine. Elmiron also works like an anticoagulant or weak “blood thinner” medication and may increase the risk of bruising or bleeding.

Always read the patient information and instructions carefully before using this medication.

  • Elmiron should be taken orally at least one or before or two hours after meals. It is typically prescribed to be taken three times a day.
  • Pentosan polysulfate sodium is most effective when it is taken regularly. Try to take it at the same time each day.
  • You should not change or increase your Lexapro dosage unless advised to by a doctor.
  • Tell your doctor if your conditions worsens or does not improve after three months.


Make sure to tell your doctor and pharmacist:

  • If you have any drug allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of bleeding disorders, blood vessel disorders, liver disease, spleen disorders, stomach disorders or intestinal disorders.
  • If you are breast feeding.

Also be aware that:

  • Elmiron should only be used when clearly needed during pregnancy.
  • You should tell all of your doctors and dentists that you take Elmiron.

Side Effects

Less serious Elmiron side effects may include but are not limited to:

  • Nausea, diarrhea or stomach pain.
  • Headache.
  • Hair loss.
  • Mild dizziness.
  • Depressed mood.
  • Mild itching or skin rash.

Contact your doctor if you experience any of the following Elmiron side effects:

  • Nosebleeds, bleeding gums or rectal bleeding.
  • Spitting or coughing up blood.
  • Blood in your urine or stools.
  • Feeling like you might pass out.



Q: What should I do if I miss a dose of Elmiron?

A: If you miss a dose of Elmiron, take the missed dose as soon as you remember but skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up for a missed dose.
