I am diabetic for the last 12 years. When I just crossed the border levels my doctor prescribed me gluconorm st 500 mg .later it was increased to twice daily. Now I am taking 1000mf in the morning 1000 mg in the evening without consulting doctor .my glucose levels fasting 240 .thats why I have started taking luke above.in this covid time I am afraid of going for testing and going to doctor too. I am testing with glucometre. After taking 1000 mg its reduced to 119 fasting. Now can you please suggest me is it proper to take such high doses of met for min. Please suggest me any safe combination medicine.
