Hydrostomate is a specialist rehydration drink for people who don’t have a colon.

How to use Hydrostomate:

Dissolve the contents of one Hydrostomate sachet in 500ml of drinking water. Stir well and wait for the solution to dissolve. Use fresh drinking water.

For sparkling water, half fill the vessel before adding the sachet contents. Allow to settle before topping up. Product should dissolve by itself in a few seconds.

If refrigerated the solution may be stored for up to 24 hours, otherwise any solution remaining one hour after reconstitution should be discarded.

Hydrostomate should only be reconstituted with water and to the volume stated. A lesser or greater dilution may result in electrolyte imbalance.

DOSE – 1 sachet per day unless otherwise directed your doctor, dietitian, pharmacist or stoma nurse.

ADULTS (including elderly) – One or two sachets per day for adults who do not have a colon.

CHILDREN – Only to be used in children and infants if advised by your doctor, dietitian, stoma nurse or pharmacist.

Hazards and Cautions:

PRECAUTIONS: If you are suffering from intestinal obstruction, diabetes, kidney or liver failure, or are on a low sodium diet, ask your doctor or pharmacist before using Hydrostomate. Infants under the age of 2 years with diarrhoea should be seen by a physician as soon as possible.
