I have been on Dapagliflazon for about 5 months.side effects, Increased thirst, peeing much more, after about 2 months I noticed indigestion, headaches light headiness, weariness, lack of energy. I have stopped taking it to judge it's effects, after about a week they seemed to subside. I then started again after taking two these symptoms returned. I have stopped again. I have done some research on the Blood sugar 101 website which is American were it advises "do not to take this drug", give it 5 years, more alarmingly it has not been licensed by the American F.D.A.
