It doesn't.: You need relatively normal kidney function to take metformin, but metformin doesn't cause kidney problems. If you take metformin when you have poor kidney function, you may run the risk of lactic acidosis, which can make you very ill. Metformin is very safe, however, for people with normal overall health.
