In addition, taking metformin in the long run can lead to kidney failure, digestive disease, diarrhea, etc.so, despite of no kidney problems, patients with diabetes should not rely on metformin in the long term. As a consequent, we can know that metformin has side effects on kidney, doing harm to kidney function.
Through the above analysis, we can see metformin itself can not induce kidney failure, but its side effect can become a main cause of kidney damage. In addition, the drug can also cause other side effects, especially gastrointestinal distress.etformin is an oral antidiabetic drug and it is the first-line drug of choice for the treatment of type 2 diabetes, in particalar in overweight and obese people and those with normal kidney function.
