The affects of Ritalins on children's Kidneys

I am doing research on the effects of Ritalin on the vital organs of the children who are taking them. I need to know if there are any adverse effects on the kidneys, such as kidney failure. Thank You

Dear Ms. Higbee,

We know the effects of long-term use of Ritalin because many people who are now in their adult years used Ritalin as children. In fact, of all the medications used with children, Ritalin is one of the most researched medications. Kidney damage does not occur with use of Ritalin.
