What is in this leaflet
This leaflet answers some common questions about PENTASA.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
Please read this leaflet before you start using PENTASA.
All medicines have risks and benefits. Your doctor has weighed the risks of you using PENTASA against the benefits they expect it will have for you.
If you have any concerns about using this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What PENTASA is used for
This medicine is used to treat ulcerative proctosigmoiditis and/or left-sided ulcerative colitis. These are conditions with inflammation, ulcers and sores in the rectum (back passage) and in the large bowel next to the rectum causing bleeding, stomach pain, and diarrhoea.
The active ingredient in this medicine is mesalazine. It is an anti-inflammatory agent, similar to aspirin and is thought to work by helping to reduce inflammation in the large bowel and rectum.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
There is no evidence that PENTASA is addictive.
It is available only with a doctor's prescription.
It is not expected to affect your ability to drive a car or operate machinery.
Before you use PENTASA
When you must not use it
Do not use PENTASA if you have an allergy to:
- any medicine containing mesalazine or aspirin-like medicines
- any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
- shortness of breath, wheezing or difficulty breathing
- swelling of the face, lips, tongue or other parts of the body
- rash, itching or hives on the skin.
Do not use PENTASA if you have a severe kidney or liver problem.
Do not use this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
Do not give PENTASA to a child 12 years old or under.
The safety and effectiveness of PENTASA in this age group have not been established.
Before you start to use it
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
- a known allergy to PENTASA, sulfasalazine or aspirin-like medicines, or any of the ingredients listed at the end of this leaflet
- a kidney or liver problem
- a bleeding disorder
- a history of asthma.
Tell your doctor if you are pregnant or plan to become pregnant or are breast-feeding.
Your doctor can discuss with you the risks and benefits involved. PENTASA should be used with caution during pregnancy and breast-feeding and only if the potential benefits outweigh the possible risks in the opinion of the doctor. The underlying condition itself (inflammatory bowel disease) may increase risks for the pregnancy outcome.
If you have not told your doctor about any of the above, tell him/her before you start using PENTASA.
Using other medicines
Tell your doctor or pharmacist if you are using any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
There is no information available on interactions between PENTASA and other medicines. However, mesalazine belongs to a group of medicines called salicylates that may interfere with the following types of medicines:
- anti-coagulants, used to thin blood or stop blood clots (e.g. warfarin)
- glucocorticoids, used to treat inflammation, swelling or allergies (e.g. prednisolone)
- sulphonylureas, used to lower blood sugar and treat diabetes (e.g. glibenclamide, glipizide)
- methotrexate, used to treat some kinds of cancers and arthritis
- probenicid or sulfinpyrazone, used to treat gout
- spirinolactone or frusemide, used to increase the amount of urine produced, and to lower blood pressure
- rifampicin, used to treat tuberculosis
- azathioprine, used to suppress the immune system
- mercaptopurine and thioguanine, used to treat leukaemia.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
How to use PENTASA
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If possible, go to the toilet and empty your bowels before using an enema. The enema will work better if the bowel has been emptied.
Insert the contents of the enema in the rectum (back passage). Keep lying down for 5 to 10 minutes.
Detailed instructions for use are available in the pack.
Do not swallow the enema.
You may experience a little discomfort and a feeling of urgency to empty your bowels immediately after inserting the enema. This is normal and expected due to the inflammation present within the bowel. Try to resist this urge to empty your bowels for as long as possible. This feeling will subside as treatment continues and the inflammation decreases.
Even if you retain just a portion of the enema, it is a step in the right direction.
If you do not understand the instructions on the packaging, ask your doctor or pharmacist for help.
How much to use
Use as directed by your doctor.
Usual dose: the contents of one enema (1g) inserted into the rectum at bedtime.
How long to use it
Continue using your medicine for as long as your doctor tells you.
This medicine helps to control your condition, but does not cure it. It is important to keep using your medicine even if you feel well.
If you forget to use it
If it is almost time for your next enema, skip the one you missed and use your next enema when you are meant to.
Otherwise, use it as soon as you remember and then go back to using your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.
If you use too much (overdose) or swallow the medicine
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have used too much PENTASA, particularly if the medicine has been taken by mouth. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
