    Imodium Instants are orodispersible tablets which contain loperamide which helps to reduce diarrhoea by slowing down the bowel.

    This medication can be used to treat short-term diarrhoea and IBS diarrhoea.


    Please check the patient information leaflet provided with the treatment to see how many tablets to take.

    The correct number of tablets are placed on the tongue which then dissolve quickly.

    These tablets do not need to be swallowed with water or chewed.

    For short-term diarrhoea:

    • Adults and children over 12 years – take 2 tablets to start treatment. Then take 1 tablet after each episode of diarrhoea.
    • Take up to a maximum of 6 tablets per day.
