I just ran across an abstract reporting increased uric acid and risk of uric acid stones in users of Topamax. This adds to my list--I'd already found an abstract on the increased risk of calcium phosphate stones. The uric acid research group recommends increasing fluid intake if on Topamax. I would think if you have a history of kidney stones it might be a good idea to discuss with your physician the possibility that another medication may be more appropriate.
