I'm looking for some advice please. After being taken off my diabetes medication Metformin 500mg x 2 twice a day , for 2 months, I have now been prescribed with sitagliptin 100mg to be taken one a day. Previously my BG was in the 18 to 28 range and my hb1ac increased from 60 to 82. After three weeks my daily BG is still in the same range. I have an appointment booked for April, but I am unsure whether to request an appointment before then. Any advice would be appreciated.
