My fbs this morning was 111, but 4 hrs later it was 160 (breakfast had only 17g carb-a piece of flaxseed bread).linically speaking, metformin peaks in the system 1-3 hours after taking it. It has a half-life of 6.2-17.6 hours. It is not metabolized, but secreted in the urine. The mechanism of action is thought to be due to increasing the binding of insulin to its receptor, which means it improves tissue sensitivity to insulin.
