Diabetes, Type 2
"I have been prescribed this combination of Metformin 500/ Sitagliptin50mg once a day in the morning dose. But it is not working as I am taking this for last 1 year, my HbA1c has raised to 7 from 5.7 Bad to note my  Postprandial glucose levels are not in control where as with 1000Mg of Metformin over night I found the levels are more controlled. I dont understand what to do ? Because from controlled level this has gone uncontrolled. Sitagliptin is not working - thus I believe."
