We cannot advise you to use the product beyond its expiry date.

Can I give my pet (e.g., cat or dog) Hydralyte?

There are many benefits of electrolytes for dogs and cats. Unfortunately we only made Hydralyte specifically for humans, so although we cannot advise you to give Hydralyte to your best (pet) friend, we do suggest you consult your veterinarian.

Can I prepare a solution from Hydralyte Powders or Tablets and freeze it?

If you'd like to try Hydralyte frozen, we highly recommend you try our Freezer Pops. Freezing tablets or powders may make the product less effective. Please follow directions for use on Hydralyte packaging.

How long do I take Hydralyte for?

Drink Hydralyte when thirsty or exhibiting signs of dehydration, or while symptoms persist. However, seek medical advice if vomiting or diarrhea persists for more than:

  • 12 hours in children under 3 years
  • 24 hours in children aged between 3 years to adults

If you are taking Hydralyte for a chronic medical condition, ensure you are seeking the advice of your doctor regarding the long-term management of your condition.

Is Hydralyte suitable for people with diabetes?

Hydralyte contains 1.5-1.6 glucose monohydrate per 4fl oz (100 ml). (Equivalent to 1.45 g Glucose anhydrous)

For people with diabetes this amount of glucose may or may not be considered safe depending on your blood glucose control and medication use. This applies to both type 1 and type 2 diabetes. Always consult your healthcare professional before adding a new product to your diet.

When unwell with diarrhea or vomiting, it is important to replace your body’s lost electrolytes, even for people with diabetes. Hydralyte can help provide important electrolytes, even for people with diabetes. Hydralyte can help provide important electrolytes and a small amount of glucose to help maintain blood glucose levels. Monitoring of blood glucose levels during any illness is very important.

If you have vomiting and diarrhea with considerable fluid loss, you should consult your healthcare professional and discuss monitoring and management of your glucose levels.

Is it normal that Hydralyte Oral Electrolyte Powder is clumped?

The powder may clump over time, particularly if held at temperatures above 86 °F (30 °C). This is a natural process due to a small quantity of moisture held in the ingredient crystals (e.g., glucose).

If the powder is clumped, but quite dry, there is no quality defect. It will dissolve in water and the active ingredients remain effective.

If the powder appears moist or very sticky, we can provide you with a replacement.

What are the directions for use for very young children (1-3 years old)?

Hydralyte is generally safe to use in children 1-3 years of age; however, you should consult the child’s healthcare professional prior to use. Refer to product packaging for usage directions (see question 26).

Hydralyte in all children should be used with the supervision of a healthcare professional. Please refer to product packaging for usage directions in children under 12 months of age.

For very young infants it is advised to give small quantities of Hydralyte slowly and regularly (e.g., 1 teaspoon every 10 minutes). Ensure you have seen a healthcare provider promptly.

Continue with breast or formula-feeding of infants between sips of Hydralyte.

Can I take too much Hydralyte?

Patients should not take more Hydralyte than is advised on the packaging. Please refer to Hydralyte packaging for usage directions.

Is Hydralyte suitable for pregnant or breastfeeding mothers?

If you're pregnant or nursing, congratulations! Hydralyte is safe to consume if you're pregnant or nursing but we always recommend you consult with your doctor.

What does ‘use under medical supervision’ mean?

We know, the saying 'use under medical supervision’ can seem scary, but Hydralyte was created as a medical food first & foremost.

As such, it is a food formulated to be used under the supervision of a healthcare professional for the dietary management of dehydration.

How long can I use Hydralyte after opening or preparation?

We have a sneaky suspicion that you'll love Hydralyte so much that leftovers will be few and far between. However, in the case that you don't sip all of this deliciousness at once:

  • Hydralyte Ready to Drink Electrolyte Solutions – Refrigerate after opening and discard 1 month after opening.
  • Hydralyte Electrolyte Powders and Hydralyte Effervescent Electrolyte Tablets – 2 hours after preparation (or 24 hours after preparation if refrigerated).

We also provide all of this information on our label/packing, so please be sure to take a look if you have any further questions.

What dosage of Hydralyte should I take?

The dosage depends on a few factors, such as age and weight. Here are the basics of how much Hydralyte to use.

Tired or have a headache, start small

 

If a headache creeps up or you feel some fatigue, start with a packet or two (if in powder form). See how you feel from there. It’s best to start with the least amount and increase gradually.

 

 

Fairly thirsty or dehydrated already

 

If you’ve barely drunk water, had a really sweaty workout or just got in from a very hot day, the middle dose of Hydralyte (halfway on the spectrum of what’s on package) is probably perfect.

Serious fever, sickness, diarrhea or vomiting

 

If you’re having intense symptoms, your body has likely lost a lot of fluid already. You likely need the higher level of doses recommended on the package, but do consult your doctor for severe or “serious” dehydration. Learn more here.

How do I use Hydralyte Effervescent Electrolyte Tablets?

  • Remove two tablets from tube and replace the cap tightly. Dissolve the tablets into 200 mL (7 fl oz) of water.
  • Sip slowly and frequently while symptoms persist. Discard unused solution after 2 hours, or 24 hours if refrigerated.
  • Always dissolve in water. Never place tablet directly into mouth.
  • Do not use if cap seal is broken. Replace the cap tightly after use.
