What ELMIRON is used for and how it works

ELMIRON is an oral treatment for interstitial cystitis otherwise known as a chronic inflammation of the bladder wall. ELMIRON is passed by the kidneys into the urine, where it coats the damaged bladder wall. This improves the bladder’s protective lining. After taking ELMIRON, it may be at least six to eight weeks before you notice improvement in your symptoms.

Advice before using ELMIRON

Use ELMIRON only when prescribed by your doctor.

All medicines have benefits and risks. In deciding to give you ELMIRON, your doctor has weighed the risks of taking ELMIRON against the benefits he/she expects it will have for you.

When should I not use ELMIRON?

ELMIRON should not be used by people who:

  • have known hypersensitivity to these kinds of drugs,
  • have haemophilia,
  • have active (or a recent history of) bleeding,
  • are currently using heparin or oral anti-coagulant therapy,
  • are pregnant, or intend to become pregnant,
  • are less than 18 years of age.

If you are not sure whether you should start using ELMIRON, contact your doctor.

When should I be careful using ELMIRON?

If you have a bleeding disorder, or you are taking anti-coagulant therapy, or you are at greater risk of bleeding (e.g. you are an alcoholic), you should tell your doctor before beginning treatment with ELMIRON.

Eating and drinking (e.g. milk, tea, coffee) interferes with the absorption of ELMIRON and so it is very important that you do not eat or drink for one hour after taking ELMIRON and that you take ELMIRON at least two hours after meals.

Should I use ELMIRON during pregnancy or breast-feeding?

  • Pregnancy
    ELMIRON should not be used during pregnancy. You should tell your doctor if you are pregnant or intend to become pregnant.
  • Breast-feeding
    Do not use ELMIRON while breast-feeding. If you intend to breast-feed, consult your doctor.

Am I restricted in my daily activities while using ELMIRON?

There are no known restrictions associated with taking ELMIRON.

Should I use ELMIRON with other medicines?

There are some medicines which may affect the way ELMIRON works. Tell your doctor about any other medicines that you take, especially heparin or oral anti-coagulant therapy. Also tell your doctor about all the medicines you have bought without a doctor’s prescription.

How to use ELMIRON properly

How much ELMIRON should I take?

The dose will be decided by your doctor and will depend on your condition. Do not take more capsules than you have been prescribed.

When should I take ELMIRON?

Normally, you should take ELMIRON three times a day unless your doctor tells you to do otherwise. Follow the pharmacist label on the pack. For the best results take the capsules at the same time each day. This will also help you to remember.

It is very important that you take ELMIRON:

  • with a small glass of water,
  • at least 2 hours after eating food or drinking, and
  • that you do not eat food or drink for one hour after taking ELMIRON.

It is suggested that you take ELMIRON when your stomach is empty.

How long do I need to take ELMIRON?

ELMIRON controls your condition but does not cure it. Therefore ELMIRON must be taken every day. Continue taking ELMIRON for as long as your doctor prescribes. If you stop taking ELMIRON, the positive effects may gradually wear off.

What if I miss a dose?

If you miss taking your ELMIRON, skip the missed dose and take your next dose as you normally would. If you have trouble remembering to take your tablets, talk to your pharmacist for some helpful hints.
