What is Dioralyte?

Dioralyte is a fluid replacement product for the treatment or prevention of dehydration, typically due to diarrhoea, which can quickly lead to an extreme loss of water and electrolytes. With diarrhoea, the body can lose more fluid than it takes in, leaving you without enough fluid for normal bodily functions.

Sign of dehydration include:

  • Confusion
  • Decreased urination or dark urine
  • Dizziness
  • Dry skin
  • Extreme thirst
  • Fast heart rate
  • Irritable behaviour
  • Pale skin colour
  • Poor responsiveness

While treating diarrhoea, it is important to keep your body topped up with fluids by drinking plenty of water.

How does Dioralyte work?

Dioralyte contains rehydration salts (sodium chloride, potassium chloride and disodium hydrogen citrate) and glucose. This combination of electrolyte salts enhances the uptake of fluid by the intestines to rehydrate the body. The rehydration process reduces fluid in stool, making stools firmer and less watery.

The rehydration salts, also known as electrolytes, help the body to retain fluids more efficiently, keeping the body hydrated for longer.

How do I use Dioralyte?

You can buy Dioralyte in loose powder form. It can be taken in the following steps:

  • Open 1 sachet and pour the powder into an empty glass.
  • Add exactly 200ml (7 fl oz) of water to the glass and stir until the powder has dissolved. The solution should look milky.
  • Drink the solution in the glass

Follow your doctor's instructions for dosage when taking Dioralyte. Adults typically use one sachet of power after each loose stool. Use one 200ml (7 fl oz) glass of water per sachet.

Do not mix Dioralyte with anything other than water. When mixing, do not use more or less than 200ml (7 fl oz). Using too little or too much water may affect the effectiveness of this medicine.

Drink the solution within 1 hour of mixing at room temperature. If kept refrigerated after mixing, drink the solution within 24 hours.

Discard any unused solution after one hour, if kept at room temperature, and after 24 hours, if stored in a refrigerator.

If you have trouble keeping food or drink down, you can take this medication in small sips.

Do not use more or less than 1 sachet for each dose.

What should I do if I miss a dose of Dioralyte?

If you forget to take a dose of Dioralyte, skip that dose and take the next one as needed. Do not double up doses to make up for a missed dose.

What should I do if I take too much Dioralyte?

Taking too much Dioralyte should not be harmful unless taken in large quantities. Go to the hospital if you experience any side effects from the overdose. Take any remaining medication and the packaging with you to give to the hospital staff, so they have the specific details necessary to provide treatment.

Dioralyte side effects and cautions

Before taking Dioralyte, it is important to familiarise yourself with the patient information leaflet (PIL) enclosed with your medicine. If you have any concerns about the information in the patient information leaflet, speak to your doctor or ask a pharmacist for advice.

If you experience the signs and symptoms of an allergic reaction, stop taking Dioralyte and seek immediate medical help.

Signs of an allergic reaction may include:

  • Swelling of the face, lips, tongue, throat, or extremities (hands and feet)
  • Skin rash (Hives)
  • Difficulty breathing or swallowing

For serious reactions, you should go straight to the casualty department of your nearest hospital. Take any remaining medicine and packaging with you so doctors know exactly what you took.

Dioralyte is well tolerated and does not typically cause side effects. Tell your doctor if you experience any of the following:

  • Abdominal pain
  • Constipation
  • Dizziness
  • Fever
  • Headaches
  • Nausea
  • Swelling of the abdomen

This is not an exhaustive list of potential side effects. Discuss any side effects you experience with your doctor or a pharmacist for further advice.

  • are on a low potassium or sodium diet
  • are unable to keep fluids down
  • have diabetes
  • have kidney disease
  • have liver disease
  • have or suspect a partial or full intestinal blockage
  • have trouble digesting or tolerating some forms of sugar

Dioralyte interactions

Tell your doctor if you are taking other medications including over-the-counter drugs and herbal supplements. Dioralyte may affect how other medications work or certain medications may interfere with how Dioralyte works.

If the diarrhoea lasts longer than 36 hours, see your doctor to determine the cause.

Check the expiration date on both the Dioralyte carton and each sachet. The date is printed as a month after EXP. The product expires on the last day of that month. Do not discard the medication in the household waste. You can also take any remaining medication to your pharmacist for proper disposal.

Always keep medicines out of the sight and reach of children and pets.

Never share your medicine with anyone else, even if they exhibit the same symptoms as you.
