Abstract: The present disclosure is directed to oral rehydration solutions, and the use of these solutions to prevent dehydration due to fever. The oral rehydration solutions of the present disclosure may be oral rehydration solutions comprising about 12 mEq/L to about 18 mEq/L of sodium, from about 11 g/L to about 60 g/L of dextrose, a zinc source, and less than about 25 mEq/L of citrates. The pH of the oral rehydration solutions can be controlled by adjusting the amount of dextrose present in the oral rehydration solutions, allowing for formulation of oral rehydration solutions comprising lower levels of citrates.
