What are Dioralyte sachets?
Dioralyte sachets are an oral rehydration treatment, flavoured with blackcurrant, that you mix with water and then drink. They’re available over the counter, meaning they don’t require a prescription.
What are they used for?
Dioralyte Sachets are designed to help if you’re dealing with dehydration caused by diarrhoea.
How do Dioralyte sachets work?
Dioralyte Sachets work by replacing the water and salts lost from your body when you’re dehydrated. They contain a balance of salts and glucose to help you absorb electrolytes and water more efficiently, keeping your body healthy even if you don’t feel your best.
How long do they take to work?
Dioralyte Sachets are a fast and effective treatment, helping to rehydrate you once the solution is absorbed in your body.
How long do they last?
The drink should be made just before it's going to be taken. You should throw away any remaining drink after one hour, or 24 hours if stored in a refrigerator.
How to use Dioralyte sachets
Adults (including the elderly) should use one or two sachets. Children should use one sachet.
To use Dioralyte Sachets, you should:
- 1. Empty the contents of the sachet(s) into a glass.
- 2. Add 200ml of water.
- 3. Stir until the powder dissolves.

How many Dioralyte sachets can you take in 24 hours?
