Description
IMODIUM (Loperamide) 2 mg: relief from diarrhoea
Imodium contains loperamide 2 mg. It relieves diarrhoea, including travellers’ diarrhoea, by slowing down the movement of the gut so more water is absorbed from the stool.
How to take it
- Adults and children 12 years and over: 2 tablets (4 mg) after the first loose stool, then 1 tablet (2 mg) after each loose stool that follows.
- Don’t take more than 4 tablets (8 mg) in 24 hours.
- Children under 12: ask a doctor. A lower dose is used for children.
- Drink plenty of fluids to replace what you lose with diarrhoea.
Do not use if you have
- Bloody or black stools
- A fever
- Mucus in your stool
- An allergy to loperamide
Heart warning
Taking more than the recommended dose can cause serious heart rhythm problems, which can be fatal. Never take more than directed. Ask a doctor or pharmacist before use if you take other medicines, as some can raise loperamide levels in the body.
Stop using it and ask a doctor if
- Diarrhoea lasts more than 2 days
- Your stomach becomes swollen or bloated
- You get a rash or other allergic reaction
- You feel faint or have a fast or irregular heartbeat
