To the Editor.
A significant change, as evidenced by recent advertisements, has been made in the composition of Pedialyte oral rehydration solutions. Pedialyte, flavored or unflavored, now contains 45 mEq of sodium per liter (an increase of 15 mEq) and 2.5% glucose (a decrease of 2.5%), and it is suitable for maintenance as well as mild dehydration. The sodium content of Pedialyte RS has been increased to 75 mEq/L, suitable for initial repair of losses of moderate or severe diarrhea, but it should be used with caution in any maintenance regimen in young infants.
