Hi has anyone been on this medication for a few years. I'm a T2 and have been for about 5 years a year ago my Metformin which never agreed with my system became un manageable I was living at the loo. And it was not controlling my BG ac1 up to 63 even though I do 60min exercise each day and keep my daily carbs intake low not but not exstreamly low as some. After discussing with my doctor I reduced my 1 year ago I now take two Metformin 500mg sr and take one 25mg of alogliptin for the 1st 6 months my average daily checks were all good and 6months ago my a1c was down to 51 but I noted my levels are climbing again yet I keep cutting back on carbs and now do 75min of exercise each day I've due blood test in a couple of weeks but already know my levels are going to be rising again. Is this likely to be medication no longer working or insulin production reducing. I'm male aged 72 about 8lbs over ideal weight.
