Hi I was diagnosed with type 2 last year and was on just diet control but my last A1C result was high . I went to see my Diabetic nurse and she prescribed me Metformin 500 mg 2 tablets with breakfast and 2 with dinner. My question is, is this normal dose of Metformin? Nurse said to me because of my age she need to give me high dose so I won't get any complications in future. I am 34, body weight 170kg and height 5'11.
