Loperamide product information

Loperamide helps to reduce diarrhoea by slowing down your bowel.  It also allows water and salts lost during diarrhoea to be absorbed by the body, helping to reduce risk of dehydration. It is used for short term diarrhoea that lasts up to 48 hours. Imodium is a brand name for loperamide capsules.

How to take

The usual dose for travellers' diarrhoea is to 2 capsules to begin and to take 1 capsule after each loose stool. The capsules should be taken whole with a drink of water. You should not take more than 6 capsules within 24 hours. 

Side effects of Loperamide

The most common side effects are usually mild and include feeling sick, constipation, winds and headache. If you are affected by dizziness, you should avoid driving or operating machinery.
However, if you develop severe allergic reactions with symptoms such as difficulty breathing, swollen eyes, face or lips and rash or itching, you should stop taking loperamide immediately and seek urgent medical advice.
