Hello, Ive never read anywhere about acute renal failure caused by tokamak! It can cause Liguria sometimes which means a lower urine volume, which under certain circumstances may aggravate renal function and lead to acute renal failure (for example: in deny Chat Doctor.  Tokamak increased the rate of renal stone formation, which may lead to obstruction of the urinary tract and cause renal failure. Obstruction causes severe pain, so you should know it if something like that happened in your case. Topamax may - rarely - cause hypokalemia. Hypokalemia can also be caused by poly uric renal failure. Renal failure may present with either Liguria (less urine) or polyuria (excessive urine) and sometimes Liguria is followed by polyuria. When too much water is excreted, potassium is lost as well. So if you're passing liters of urine every day then a low potassium level can be attributed to polyuria. So in conclusion, I don't believe Tokamak caused renal failure to you because there are not any reports that I know about such a side effect of this
