Hi, I met general practitioner. He diagnosed me with candidiasis genital. He prescribed duflucan 1 tablet only, and interzol (ketoconazole 2%) cream twice daily. I applied interzol for one week and stopped it as I see it was getting better. Now its been a week, and I again see the problem reoccur. I do not have interzol, but I have kz cream (ketoconazole. Is it safe to apply on penile head and for how long I should continue applying the cream.
