###Human: Which are the best medicines to reduce blood sugar? ###Assistant: Hello. I think the dosage is less for complete control of the sugar levels. Let her take one tablet at morning and 1.5 tablets at night and let me know her sugar levels. This new medicine has less dosage in comparison to the one she was taking earlier. Hence it must have lead to changes in her blood sugars. Also, I would like to ask if she is following a diabetic diet and does she exercise regularly? It is equally important as her medicines and would also make the medicines more effective. Let me know her readings post this change. So I can advise accordingly further ahead.
