I want to know if my relative is taking the right dose of medication for diabetes. Kindly suggest.

Hi doctor,

I am sending a few doubts of my relative, who is suffering from diabetes and HTN. They have a strong case history of CKD in the family. For diabetes, the patient was taking the following medicines. A combination of Metformin 850 mg and Glimperide 1 mg in the morning and a combination of Metformin 850 mg and Glimperide 2 mg at night. His sugar was not under control, and he went to a doctor, who changed all his medicines, and later on, he tapers down the medication. After taking the above medicines, he found his RBS as 297 mg/dL, and he went to this new doctor and prescribed him Tiban 20/500 mg twice a day and Crano-D once a day (This is a combination of Manrose 600 mg and Cranberry extraction 300 mg). He measured sugar in regular intervals, and his sugar was coming down.

Now he has an RBS of 100 mg/dL, and the doctor gave him Tiban 20/500 mg once a day and Crano D once a day. Now he doubts that whether he has been given heavy doses of medicines. Is the present given drugs have equal strength compared to his previous medications? Since they have a family history of CKD, they approached me to determine whether they are on the right track or misled by prescribing high doses first and then reducing slowly.

Please guide.
