Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about STOP-IT.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking STOP-IT against the benefits expected to have for you.

If you have any concerns about using STOP-IT ask your doctor or pharmacist.

Keep this leaflet with your medicine. You may need to read it again.

What STOP-IT is used for

STOP-IT is used to treat sudden (acute) diarrhoea or long-lasting (chronic) diarrhoea.

STOP-IT 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 STOP-IT for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.
