Does metformin affect the liver or kidneys?

My doctor just prescribed me Metformin for my high sugar levels, and I am a bit scared to start it. Does anyone know how often we need to get blood tests done to monitor the kidneys? I want to make sure I am doing everything correctly.

I was researching this because my dad takes it. From what I read, Metformin is actually cleared by the kidneys, not metabolized by the liver, so it doesn't cause liver damage. The main concern is that if kidneys are already weak, the drug can build up and cause lactic acidosis, which is why doctors monitor kidney health.

You must check your kidney function with a proper creatinine test before starting or continuing Metformin. While it is a standard medicine, it is contraindicated in patients with severe kidney disease. Always let your doctor look at your latest blood reports to confirm if it's safe for you.

Hey there! Don't worry too much. Metformin is actually considered very safe and doesn't directly cause damage, but if your kidneys are already working a bit slow, the doctor might adjust the dose. Just stay hydrated and keep up with your normal lab tests!

Please make sure you get regular blood tests done. I ignored my routine checkups while taking daily meds and ended up with elevated creatinine levels before my doctor caught it. Get your kidney function test (KFT) and liver function test (LFT) done every six months without fail.
