Any one who's gone off Metformin . . . how long does it stay in your system?? I know it takes 2 - 3 weeks to kick in when you start taking it, how long does it take to completely leave your system when you stop? Due to my increase in exercise and lowering of carbs I have stopped taking it (2nd day) but feel that kind of weird lowish, head spinny thing.
Three out of 10 people who take metformin long-term develop a deficiency of vitamin B12. It can take 10 or 15 years to develop symptoms of B12 deficiency since the liver stores B12 - and it can take that long to deplete those stores.B12 deficiency causes damage to nerves that may be irreversible.urrent guidelines indicate that metformin is a cornerstone in the treatment of type 2 diabetes, but make no recommendations on the detection and prevention of vitamin B-12 deficiency during treatment. Our data provide a strong case for routine assessment of vitamin B-12 levels during long term treatment with metformin.
