About Imodium
Imodium is a well-known brand for the relief of acute (short-term) diarrhoea. Its active ingredient, loperamide, works by slowing down the movement of the gut, helping to restore a more normal rhythm and reduce the number of trips to the toilet.
The range includes Imodium capsules, fast-melting Instants, and Imodium Plus, which combines loperamide with simeticone to also ease the painful cramps and bloating that can come with diarrhoea.
Browse the Imodium range below, dispatched from our UK pharmacy. Always read the label and the enclosed patient information leaflet before use, and drink plenty of fluids to stay hydrated.
Frequently asked questions
What does Imodium do?
Imodium relieves short-term diarrhoea by slowing the muscle movements of the gut, which allows more water to be absorbed and makes stools firmer and less frequent. It treats the symptom rather than the underlying cause.
How does Imodium work?
Its active ingredient loperamide acts on the muscles of the intestinal wall, slowing the passage of contents through the bowel. This gives the body more time to absorb water and salts, easing diarrhoea.
How long does Imodium take to work?
Many people notice an improvement within about an hour, though this varies from person to person. If your diarrhoea does not improve within 48 hours, stop taking it and speak to a pharmacist or GP.
How do you take Imodium?
Follow the directions on the pack: typically two capsules are taken to start, then one after each loose stool, without exceeding the stated daily maximum. Always read the patient information leaflet first.
How many Imodium can you take in a day?
The maximum daily dose is stated on the packaging and differs between products and between adults and children, so always check the label. Never exceed the stated maximum, as taking too much loperamide can be dangerous, including effects on the heart.
Is it harmful to take Imodium every day?
Imodium is intended for short-term use. Regular or long-term diarrhoea should be assessed by a GP to find the cause, so do not take it daily over long periods without medical advice.
Does Imodium help with nausea?
Imodium is for diarrhoea and is not a treatment for nausea or vomiting. If nausea is your main symptom, speak to a pharmacist about a more suitable product.
When should I see a doctor instead of taking Imodium?
Seek medical advice if there is blood or mucus in your stools, a high fever, severe stomach pain, or if diarrhoea lasts more than 48 hours, and for anyone who becomes dehydrated. It is not suitable for some conditions, so read the leaflet carefully.
Can I give my dog Imodium?
Human medicines should not be given to pets without veterinary guidance, as the safe dose and suitability differ and loperamide is not appropriate for some dogs. Speak to your vet before giving your dog anything for diarrhoea.
