Hydralyte Sachets (10)

Hydralyte sachets replace the electrolytes lost through vomiting, diarrhoea, heavy sweating and other dehydrating conditions. Each sachet dissolves into a measured oral rehydration drink containing sodium, potassium, glucose and citrate in a set ratio - the point being that it is formulated, not just flavoured. This is the 10-sachet pack.

Why choose Hydralyte sachets over water or soft drink

Water alone replaces volume but not what was lost with it. An episode of vomiting or diarrhoea strips sodium and potassium out along with the fluid, and drinking plain water dilutes what is left. Each sachet supplies sodium chloride 0.53g, potassium citrate 0.44g, anhydrous citric acid 0.88g and anhydrous glucose 2.91g in roughly 4.9g of powder - the salts as well as the water.

The glucose is there for a specific physiological reason, not for taste. Sodium and glucose are absorbed together across the gut wall, so including glucose in the right proportion is what lets the sodium - and the water with it - be taken up when the gut is upset. That co-transport ratio is the entire design principle behind oral rehydration formulas, and it is why soft drink and sports drink are poor substitutes: far too much sugar, almost no sodium.

Sachets suit the household that wants rehydration on hand without dedicating fridge space. They are shelf-stable, light, and each one is a single measured dose - so there is nothing to estimate at 3am, and nothing that goes off between the gastro episodes you are actually buying them for. Ten to a pack covers a typical episode for one person.

Common uses

Gastro is the obvious reason, but the sachets earn their place just as often in heat - outdoor trades, sport, and travel to hot climates, where sweat losses build up quietly across a day. Households with young children tend to keep both formats: sachets for adults and for making up a drink, and Hydralyte ice blocks for a child who will not drink but will take an ice block. If diarrhoea symptoms also need controlling for travel or work, Gastro-Stop is the companion product - though rehydration remains the part that matters clinically.
