Diarrhoea

Treating diarrhoea and staying hydrated

The most important part of managing diarrhoea is replacing lost fluids and salts, which is where oral rehydration sachets such as Dioralyte help — especially for children, older adults and anyone at risk of dehydration. Anti-diarrhoeal medicines like loperamide (Imodium) can reduce the number of trips to the toilet for sudden, short-lived diarrhoea in adults, but they don't treat the underlying cause. In babies and young children, dehydration develops much faster, so seek medical advice early rather than treating at home. Drink plenty of fluids and rest.

Frequently Asked Questions

Should I use loperamide or rehydration sachets?

They do different jobs. Rehydration sachets replace lost fluid and salts and are suitable for most people, including children with guidance. Loperamide reduces the frequency of diarrhoea in adults but should not be used if there is blood in the stools or a high fever.

When should I see a doctor?

Seek advice if diarrhoea lasts more than a few days, if there is blood or mucus, a high fever, severe stomach pain, signs of dehydration, or if it affects a baby or young child, as their dehydration risk is more acute — babies should be seen promptly.

Can children take these?

Rehydration sachets can be used in children, but loperamide (Imodium) is only for those aged 12 and over. Always check the age on the pack and ask your pharmacist.
