Diarrhoea Relief

Sudden diarrhoea can upset a holiday, a working day or a family outing, so it can help to have a pack to hand at home or in your travel bag. The range brings together anti-diarrhoeal medicines containing loperamide, such as Imodium and Arret, in capsules and in tablets that melt on the tongue, alongside oral rehydration sachets from Dioralyte that replace the fluid and salts the body loses.

Melt-in-the-mouth tablets suit travel because they need no water, while capsules are the familiar choice at home. Rehydration sachets work differently, replacing fluid rather than slowing the diarrhoea, so they can be used on their own or alongside a loperamide product, which is not for children under 12. If diarrhoea lasts more than 48 hours while taking loperamide, or for a baby or young child, speak to our pharmacist or GP, and always read the label and the patient information leaflet before use. For everyday digestive care, also see our gut health range.

Frequently Asked Questions

What is the difference between loperamide capsules and Imodium Instants? +
Both contain the anti-diarrhoeal medicine loperamide. Capsules such as Arret are swallowed with water, while Imodium Instants are tablets that melt on the tongue, which some people find easier when travelling or without a drink to hand. The dose and age limits are set out on each pack, so always read the label and the patient information leaflet before use, and ask our pharmacist if you are unsure which suits you.
When should I use a rehydration sachet instead of an anti-diarrhoeal? +
Rehydration sachets such as Dioralyte replace the fluid and salts lost with diarrhoea rather than slowing it down, so they can be used on their own or alongside an anti-diarrhoeal. Older adults are more at risk of dehydration, so ask our pharmacist for advice, and get medical help if signs such as dizziness or passing little urine continue after using sachets. Always read the label and the patient information leaflet before use.
Can I take diarrhoea medicine when travelling abroad? +
Many people pack an anti-diarrhoeal and a few rehydration sachets in their travel kit. Loperamide is for short bouts of diarrhoea in adults and children aged 12 and over, and it should not be taken if you have a high temperature or blood in your stools. Keep medicines in their original packaging with the leaflet, read the label before use, and get medical help locally if symptoms are severe or do not settle.
Can loperamide be given to children? +
Loperamide medicines sold without a prescription, such as Imodium and Arret, are not for children under 12. For a child with diarrhoea, keeping up their fluids matters most, and oral rehydration sachets carry dosing information for different age groups on the pack. Speak to our pharmacist or GP before giving any product to a baby or young child, and always read the label and the patient information leaflet first.
