dear sir assalam alaikum I can understand your concern in my opinion you are taking is little powerful.This kind of powerful medications will exhaust your pancreas soon. but you should daily do exercise and diet control also with out that it s impossible to control sugars . I would like to know your duration of diabetes also which will help me to decide medication for you. remember it s very important to have good diabetes control to avoid diabetes related complications.there are new medications like DPP4 inhibitors available which are having better outcomes than glucovance regards Dr vamsi Krishna Diabetologist apollo hospitals muscat
