<s>[INST] I currently take 150 mg  of topomax daily. Have been for several years.  I recently have had a terrible time with kidney stones.  4 in the past 2 weeks. One 5mm, 3mm, 6mm, and 8mm which had to be removed by surgery.  Could the topomax be causing my stones? [/INST] Yeah topamax can cause kidney stones but there might be some other causes for it like Increased calcium levels so you should analyse the stones and get through check up </s>
