Terminal illness is a disease that cannot be cured or adequately treated and that is reasonably expected to result in the death of the patient within a short period of time.he six-month standard is arbitrary, and best available estimates of longevity may be incorrect. Consequently, though a given patient may properly be considered terminal, this is not a guarantee that the patient will die within six months.
1 Stop metformin if the eGFR is below 30 ml/minute/1.73m2.  Prescribe metformin with caution for those at risk of a sudden deterioration in kidney function and those at risk of eGFR falling below 45ml/minute/1.73m2.
How long does Metformin stay in your system? I've been taking 850mg twice daily for about 3? months and took my last one this morning. My fbs this morning was 111, but 4 hrs later it was 160 (breakfast had only 17g carb- a piece of flaxseed bread).
