What do i do for thrush, i've had it before and it came back. ?

Recurrent yeast: Are you concerned about yeast (thrush) of vagina, mouth, or elsewhere? Vaginal yeast infections often recur. If not too frequent, just treat each one. If a few times a year, make sure there's no underlying health problem causing them, especially diabetes. Periodic treatment, e.g. a fluconazole (Diflucan) pill once a week, usually can stay ahead of the problem. Discuss with your doctor.
