Managing Dehydration in Children

Hydralyte is scientifically formulated to contain the correct balance of glucose and electrolytes for rapid rehydration. The formulation is based on the World Health Organization criteria for effective rehydration. Water or sugary drinks are not as effective as Hydralyte, as they do not restore lost electrolytes (which retain the fluid).
