My blood sugar had been running very high (A1c is 8.4). I am taking glucovance (2.5/500 4xdaily) and now my doctor just added 30mg of actos. My blood sugars have been more normal and I just started taking the actos one week ago. I was told that I am taking the maximum dosage of glucovance. I feel like I am taking too much medicine and that maybe I should talk to my doctor about getting on insulin. Does anyone know another diabetic medicine that may work like glucovance that I could take with the actos? I have even lost 15 pounds so I don't know why my A1c's were so high. Could my body have become immuned to the glucovance after having been on it for so many years?
