Pharmacist Tips

  • Although Elmiron is used to treat the discomfort or pain from interstitial cystitis, it is not a pain medication like acetaminophen or aspirin, and must be taken like a maintenance medication (continuously) as prescribed to get relief.
  • You should get a retinal exam every 6 months (baseline and periodically) when starting and stopping Elmiron.
  • Speak to your doctor if you are taking any other anticoagulant agents or antiplatelet agents. This medication can increase your risk of bruising and bleeding.
