Frequently asked questions
What is Dioralyte used for?
Dioralyte is used to treat dehydration caused by diarrhoea and vomiting by replacing lost water and important salts (electrolytes). It supports recovery but does not stop the diarrhoea itself.
What does Dioralyte do?
When dissolved in water and drunk, Dioralyte replaces the fluid and electrolytes such as sodium and potassium that the body loses during a bout of diarrhoea or sickness, helping to restore normal hydration.
Does Dioralyte stop diarrhoea?
No - Dioralyte does not stop diarrhoea. It rehydrates the body and replaces lost salts while the illness runs its course. If you also want to slow the diarrhoea, ask a pharmacist about a separate treatment.
How many Dioralyte sachets can you take in a day?
The number of sachets depends on age and on how much fluid has been lost, and the daily maximum is stated on the pack, so always follow the label. Do not exceed the stated amount without medical advice.
How often can I take Dioralyte?
It is usually taken after each loose stool or episode of vomiting, within the daily limits on the pack. Made-up solution should be used within one hour, or within 24 hours if kept in the fridge.
Can you take Dioralyte without diarrhoea?
Dioralyte is intended for rehydration after fluid loss from diarrhoea or vomiting. While it replaces electrolytes, it is not designed as an everyday drink, so use it for its intended purpose and follow the label.
Is Dioralyte good for hangovers?
Because a hangover involves some dehydration, some people use rehydration salts to help. Dioralyte is licensed for fluid loss from diarrhoea and vomiting rather than hangovers, so the best remedy for a hangover is water, food and time.
Is Dioralyte an electrolyte drink?
Yes, once dissolved it provides a balanced mix of electrolytes and glucose designed to aid the absorption of water, which is what makes oral rehydration salts effective.
Can you take Dioralyte when pregnant?
Rehydration is important in pregnancy if you have diarrhoea or vomiting, but you should read the label and check with your pharmacist, midwife or GP before use, and seek advice if symptoms are severe or persistent.
How quickly does Dioralyte work?
Dioralyte starts replacing fluids and salts as soon as it is absorbed, so sipping it steadily during illness helps maintain hydration. Seek medical advice if you cannot keep fluids down.
