What is in this leaflet
This leaflet answers some common questions about IMODIUM. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking IMODIUM against the benefits this medicine is expected to have for you.
If you have any concerns about using IMODIUM ask your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What IMODIUM is used for
IMODIUM is used to treat sudden (acute) diarrhoea or long-lasting (chronic) diarrhoea.
IMODIUM is also used in patients who have had part of their intestines removed by surgery (intestinal resection).
IMODIUM makes the stools more solid and less frequent. It does this by normalising the muscle contractions of the intestine. This allows the bowel time to absorb water and produce a more solid stool.
Your doctor may have prescribed IMODIUM for another reason.
Ask your doctor if you have any questions about why IMODIUM has been prescribed for you.
