I have been prescribed for premenstrual syndrome, yeast infections Fluconazole (a pill taken once) and I took Tuesday. The package said that the symptoms should disappear within a couple of days, and are, but does not say how long it takes to completely eliminate the infection. I know I should have sex while you have a yeast infection that does not go back and forth and I wonder if I make it clear once gender or how long should I wait. Any advice would be great.
