People’s Pharmacy: Lemonade therapy for kidney stones?

Q: The other day, someone wrote asking about kidney stones. To cut down on kidney stones, I drink several glasses of lemonade a week.

A: There is some scientific basis for your observation. Doctors often prescribe potassium citrate to disrupt kidney-stone formation.

Lemonade also contains citrate, and some research shows that lemonade therapy reduces the rate of kidney-stone formation (Journal of Urology, April 2007).

Three or four glasses of lemonade per week are probably not enough to do much good, however. Studies of “lemonade therapy” have used one to two quarts of unsweetened or low-sugar lemonade daily.

300 mg of Zyloprim everyday will prevent gout and kidney stones. Inexpensive and no side effects.
