Diabetes

A diabetic female patient came about 3 months ago with fasting glucose of 250 and PP glucose of 400.
She was on sulphonylureas, poiglit, metformin, empaglioflozin, lyrica and yet her blood glucose was nowhere in control. We started her on imusil 2_0_2.

Since last 15 days she is off the allopathic anti diabetic medicines because she had a viral infection and she had no one to restock them. She was only on imusil. 
Her fasting glucose yesterday was 125 and PP glucose was 158. Her diabetologist has now changed her medications to just 500 mg metformin once a day.
