What should you know about oral rehydration salt sachet?

A sachet contains a measured blend of glucose and electrolytes. Once mixed with water, it helps replace fluid lost through diarrhoea, vomiting, sweating, or fever. It supports absorption in the intestine; it does not act as an antibiotic, painkiller, or medicine that stops every cause of diarrhoea.

The packet size is linked to a particular water volume. A half-filled cup or an oversized bottle can produce the wrong concentration. Packaging may also give storage advice and a time limit for using the mixed liquid, so keep the label available after opening.

Wash your hands, use a clean container, and measure the water specified on the sachet. Empty in the full contents, then stir until no powder remains. Do not divide a sachet by eye, add extra ingredients, or use it dry. Give frequent small sips; a spoon or cup may help a child who struggles with larger drinks.

If vomiting follows a drink, wait a short while and restart with smaller amounts. Continue breastfeeding where relevant and offer suitable food as tolerated. Make a fresh mixture according to the product instructions rather than topping up an old container.

Get emergency help for collapse, confusion, a seizure, severe breathing difficulty, or a person who cannot be woken. Prompt assessment is needed when urine becomes very scarce, the mouth is very dry, the eyes look sunken, or drinking is not possible.

Contact a clinician for blood in stool, severe tummy pain, ongoing vomiting, or a fever with marked weakness. Infants, older people, and those with kidney or heart problems may deteriorate quickly and need tailored fluid advice.

Ask how much of the prepared drink to offer, how long to continue it, and whether the person’s age, medicines, or health conditions require a different plan.
