What do you suggest if my child used lithostat (acetohydroxamic acid) to prevent kidney stones. i can't get it any more. can anyone help?

Stone prevention: Citrate is the essential ingredient to prevent kidney stones. Sodium or potassium citrate is typically used for children, but is available only by prescription as polycitra or citrapH. Using lemon extract can work just as well. A child can take three tablespoons per day, added to any beverage. Knowing why stones form in your child is essential. Then targeted therapy can be added.
