My doctor prescribed diflucan , nystatin, and triamcinolone acetonide cream for a reoccurring yeast infection. Can I use it on the inside ? I'm not sure if she said the outside or inside just remember diflucan two doses within 7 days and then mix an apply the cream to affected area. My first infection I remember putting it inside my vagina but not sure if it was the same cream. I have this boyfriend who isn't circumcised and he knows when a female has yeast an advised me to douche, I never have before and it got worse. It says external unless advised otherwise ... Help
