    Imodium Original is used to treat 2 types of diarrhoea:- short-term diarrhoea and IBS (irritable bowel syndrome) diarrhoea.

    The active ingredient in Imodium Original is loperamide which helps to reduce diarrhoea by slowing down an overactive bowel. This helps to allow the body to reabsorb water and salts which is usually lost in diarrhoea.


    For short-term diarrhoea:

    • Adults and children over 12 years – take 2 capsules to start treatment. Then take 1 capsule after each episode of diarrhoea.
    • Take up to a maximum of 6 capsules per day.
    • If diarrhoea lasts longer than 48 hours, please consult your doctor.
    • Not recommended for children under 12 years of age.

    For IBS diarrhoea which has been diagnosed by a doctor:

    • Adults aged 18 years and over – take 2 capsules to start treatment. Then take 1 capsule after each loose bowel movement or as advised by your doctor.
    • You can use this medicine for up to 2 weeks for repeated attacks but do not take for any attack lasting longer than 48 hours.
    • Do not take more than 6 capsules in 24 hours.
    • Not recommended for children and young people under 18 years of age.

    Ensure you are drinking plenty of fluids to replace lost water and salts.


    Do not take if:
    • you have had a bad reaction to loperamide or any of the ingredients
    • it is for a child under 12.
    • if you have severe diarrhoea after taking antibiotics
    • if you are constipated or stomach appears swollen
    • you are pregnant or breastfeeding

    If you are unsure, please check with your pharmacist or doctor before taking.
