About Loperamide Hydrochloride 2mg
  1. What is Loperamide Hydrochloride?

    Loperamide Hydrochloride is a treatment for diarrhoea. It is most commonly known by its brand name, Imodium.

    This medicine is used as the active ingredient in several branded diarrhoea medicines, such as Norimode.

    What is Loperamide Hydrochloride used to treat?

    Loperamide Hydrochloride is most commonly used to treat chronic diarrhoea associated with conditions such as inflammatory bowel disease and travellers’ diarrhoea. Loperamide acts as an anti-diarrhoeal agent, helping to manage symptoms.

    It can be taken by adults and children over the age of 12 and works to decrease how often you need to go to the toilet by reducing intestinal contractions.

    How does Loperamide Hydrochloride work?

    Loperamide Hydrochloride is what is known as an anti-motility medicine. It works by slowing down your food as it travels through the digestive system. It does this by reducing the contractions in the intestines.

    As a result, your body is able to draw more water in from the intestines, making your stools firmer. Because your stools are firmer, your urge to go to the toilet will be reduced significantly.

    Why is Loperamide Hydrochloride recommended for diarrhoea?

    Loperamide Hydrochloride can treat the symptoms of diarrhoea quickly and effectively, normally relieving the problem within five to seven days. It helps to slow down food as it passes through the gut, which reduces how often you need to have a bowel movement.

    Loperamide Hydrochloride has been used since 1976, it also features on the Wold Health Organisation's List of Essential Medicine.

    Who can take Loperamide Hydrochloride?

    Children under the age of 12 should never be given Loperamide Hydrochloride unless it is prescribed by a doctor.

    Loperamide Hydrochloride alternatives

    Many different medicines are available to effectively treat diarrhoea.

    Imodium is the branded version of this medication. Loperamide hydrochloride is the active ingredient contained in Imodium, so it gets to work in the same way as the generic version. It is available as a syrup or as tablets or capsules.

    Another medicine containing loperamide hydrochloride is Norimode.

  2. Loperamide Dosage

    Our pharmacists and prescribers follow NICE guidelines when prescribing Loperamide.

    Loperamide capsules should be swallowed whole with a drink of water.

    The dose you should take will depend on your symptoms and age.

    For adults with diarrhoea and IBS

    Take two capsules straight away, followed by one capsule after each runny bowel movement.

    You should stop taking Loperamide as soon as your symptoms settle down. Do not take it for more than 48 hours without speaking to your doctor.

    You should not exceed the recommended maximum daily dose. If you have bought them from a shop, this will be 6 capsules in a 24 hour period.

    If you have bought them from a pharmacy or have been prescribed them, this will be 8 capsules.

    Diarrhoea relief for adults with long-lasting diarrhoea

    Most cases of diarrhoea will be resolved in 5 to 7 days, but if it persists after 7 days, you should speak to your doctor to get to the root of the problem.

    The usual starting dose for this medicine is 2 to 4 capsules, spread throughout the day. You will likely be given a packet of 30 capsules.

    Some patients may need higher doses, such as if they suffer from stoma, but the dosage should only be increased if advised by a doctor.

    Diarrhoea relief for children

    Children over the age of 12 who have short term diarrhoea do not need a prescription for Loperamide.

    If they are aged 12 to 17 and have IBS or long lasting diarrhoea, they will need to be prescribed this medicine.

  7. Loperamide FAQ's

    How will it treat my symptoms?

    Loperamide is used to treat diarrhoea by slowing down the contractions of your intestines, providing effective relief of this condition.

    What causes diarrhoea?

    Diarrhoea is usually caused by a bowel infection (gastroenteritis). Infections usually occur thanks to viruses such as norovirus or rotavirus, parasites which spread in contaminated water, or bacteria that is often found in contaminated food. You may catch these infections if you go abroad, especially to places which have low standards of public hygiene.

    How should I store these tablets?

    Keep your diarrhoea relief capsules out of the reach of children. Store at room temperature, away from direct sunlight and moisture

    What if I forget to take a dose?

    If you miss a dose, just take another dose after the next time you go to the toilet and have a runny bowel movement.

    What if I take too much?

    Do not take more than is recommended by your doctor. Do not double up if you forget to take a dose. Accidentally taking an extra dose of Loperamide is unlikely to harm you, although higher doses than recommended can lead to serious heart problems, including an increased or irregular heartbeat. If you take more than one extra dose, you should consult your doctor of pharmacist.
