I am believed to havea penile yeast infection. i've treated with fluconazole and monstat 7. how long should it last? i've treated it with medication for 3 days and creme for 6 days.

Maybe not yeast: Persistence after these treatments suggests the problem may not be yeast; or a yeast infection resistant to the "azole" drugs. Often the diagnosis of a genital yeast or fungal infection is an educated guess by the doctor. Best to contact the doctor's office for advice about next steps -- which might include referral to a dermatologist. Good luck!
