In addition to the anecdotal evidence we had prior to this study, we now have clinical study date demonstrating that long-term use of topiramate increases the propensity for kidney stones. Dr. Sakhee commented,
"There is a legitimate concern for the occurrence of kidney stones with long-term topiramate treatment... Studies are needed to explore optimal measures to prevent kidney-stone formation with topiramate use."
If you are considering taking topiramate, please discuss this issue with your doctor, especially if you have a history of kidney stones or any problems with kidney function.
