How much can I take?

Doctor put me on 10mg Dapagliflozin a day nearly a year ago now, in basic terms it makes you pee the sugar out of your body. A side affect of this for some people is Thrush and I am one of those people, so the doctor prescribed 150mg Fluconazole, this is a simple take one tablet job. But the paperwork that comes with the tablet does not say how long that one tablet is supposed to last or how frequently I can take the Fluconazole tablet.

Does anybody else know the answer and do you have a natural remedy for dealing with Thrush (and please don't say smearing yourself in natural yogurt)

I fully understand Riva and fully intend to do so but like many, getting an appointment just to talk to the Doctor is weeks, so I was asking if anybody else had had this same issue. I would consider myself intelligent enough to not to change the dosage of my medication just because somebody else was taking something different to me, everybody is different.
