Hi doc. Last dec 2013, i had my hba1c with result of 8.09 and fbs of 6.93. So i was advice to take glucovance 500/5 once a day in two divided dose.
Last week of may, i had fbs examination and it is 6.33.
I went to another doctor and advice me to take galvusMet 50/500 but as of now i still have glucovance for a month supply. Can i maintain glucovance and not take galvusmet since the price is higher than glucovance
