The packet is used by doctors and health workers to treat dehydrated children. But it can also be used in the home to prevent dehydration. The above ingredients are to be dissolved in one litre of clean water. WHO has recently changed the formula, replacing 2.5 gms of sodium bicarbonate with 2.9 gms of trisodium citrate dihydrate. The new formula gives the packets a longer shelf life and is at least as effective in correcting acidosis and reducing stool volume.
Packets containing sodium bicarbonate are still safe and effective.
Dissolve the contents of the packet in the amount of drinking water indicated on the packet, usually 1 litre. If drinking water is not available, or if you are not sure the water is drinkable, boil the water for at least 10 minutes and then let cool. Stir well, and give to the child to drink in a cup or spoon feed. Be careful to mix the right amount of water. If you use too little water, the drink could make the diarrhoea worse.
