As Soon As My Medication - Mycelex Troche - Has

as soon as my medication - Mycelex troche - has been taken as prescribed, I get the mouth fungus, soreness back again. I have been treating this condition, under physician's care, now for at least 1-1/2 years. I have been prescribed miracle mouth wash (compounded) also. This is frustrating and at times quite painful. Any hints for further care? Thanks so much.
