Hello, With the blood glucose levels you mentioned, he needs to take antidiabetic Chat Doctor.  I would recommend getting HbA1C blood test done to see the diabetes control over the last 3 months. What is the weight of your grandfather? If he is overweight or obese, I would recommend starting him on metformin (and only if his liver function tests are normal). The dose I would start my patient on with similar blood glucose readings will be 500 mg three times a day with meals. If his weight is normal then I'd recommend resuming Glemiperide and the dose I would prescribe to my patient of the same age group would be 1 mg per day. After a week of regular use of medicine and with continuation of medications, he can get his blood glucose level checked 6 times by a glucometer, before the three meals as well as 2 hours after the three meals and according to the recorded blood glucose levels the medicine dose can be adjusted. Please do meet the treating physician of your grandfather for further evaluation. Hope I have answered your query. Let me know if I can assist you further.
