Patient leaflet - Dioralyte Citrus

1. What Dioralyte is and what it is used for

The name of your medicine is Dioralyte Natural/ Citrus/Blackcurrant (called Dioralyte throughout this leaflet). Dioralyte works by replacing the water and salts lost from your body when you have diarrhoea. It contains glucose and salts (these are sodium chloride, potassium chloride and disodium hydrogen citrate). The powder is mixed with water before taking.

2. Before you take Dioralyte

Do not take Dioralyte and talk to your doctor or pharmacist if:

  • You are allergic (hypersensitive) to glucose, sodi-um chloride, potassium chloride and disodium hydrogen citrate or any of the other ingredients of Dioralyte (see Section 6: Further information) • Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
  • Your bowel is partially or fully blocked (called ‘intestinal obstruction’)

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Dioralyte.

Take special care with Dioralyte

Check with your doctor or pharmacist before taking this medicine if:

▲ You have chronic or persistent diarrhoea ▲ You are on a low potassium or low sodium diet ▲ You have liver or kidney disease

▲ You have diabetes

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Dioralyte.

If nausea and vomiting are present with the diarrhoea, small but frequent amounts should be drunk at first.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Dioralyte can affect the way some other medicines work. Also some medicines can affect the way Dioralyte works.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine if you are pregnant or breast-feeding. This includes if you are planning to get pregnant or think that you might be pregnant. Important information about some of the ingredients of Dioralyte

This medicine contains glucose, which is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars, talk to your doctor before taking this medicine.

3. How to take Dioralyte

If you are not sure how to take this medicine, check with your doctor or pharmacist

Preparing this medicine

Dioralyte must be mixed with water before taking. • Prepare just before the medicine is going to be taken. Do not make in advance. If you are giving it to a baby over the course of the day, you can keep the drink in a refrigerator for up to 24 hours • Only dissolve the powder in water. Do not dissolve it in anything else

  • Use fresh drinking water for adults and children over 1 year old. If fresh water is not available, use water which has been freshly boiled and cooled • Always use water which has been freshly boiled and cooled for babies aged 3 months to 1 year
  • Empty the contents of 1 sachet into a glass
  • Add 200 ml (7 fl oz) of water
  • Stir until the powder dissolves

When your medicine is fully dissolved, the drink will be a colourless solution.

Do not use more or less than 200 ml of water. If you do, the drink will become too weak or too strong. It will not work as well. You may also upset the balance of salts in your body. How many sachets to take

  • If you are being sick take the medicine in small sips • It is best not to eat during the early stages of diarrhoea
  • If the diarrhoea lasts for more than 24 to 48 hours see your doctor

Adults (including the elderly)

  • One or two sachets after each loose stool Children
  • One sachet after each loose stool

Babies up to 2 years old

This medicine should only be given under the guidance of a doctor

  • The doctor will calculate how much to give your baby, depending on how much they weigh. This is usually about one to one and a half times the amount of fluid your baby normally has in 24 hours
  • Initially, if you are bottle feeding or giving other foods this should be stopped
  • If you are breast feeding, continue to feed normally. Your baby may need less breast milk so you may need to express some of your milk • Ask your doctor or pharmacist if you are not sure how much to give
  • If your baby is being sick, you can give 5-10 ml (one or two teaspoons) every 5 minutes. This can be gradually increased until they are able to drink normally

If you take more Dioralyte than you should

Dioralyte is not normally harmful if you take more than you should. However, if large amounts are taken you should talk to a doctor or go to a hospital straight away. This is particularly important if it is a child or baby or if you have severe liver or kidney problems. Take the medicine pack with you.

If you forget to take your Dioralyte

Do not take a double dose to make up for a forgotten dose. Take the next dose when you need to. If you have any further questions on the use of this product, ask your doctor or pharmacist.
