Are there any prescription treatments for oral or vaginal yeast infections?
There are prescription treatments for a yeast infection, both vaginal and in the mouth. Prescription medicines can be used to treat yeast infections in the mouth - an option that is not available in over-the-counter or alternative forms. Prescription medicines are also available for vaginal infections that are not cured by over-the-counter products. In both cases, prescription medicines can be applied to the affected areas or taken as oral tablets.
Nystatin (Mycostatin®) is a medicine that is applied to the mouth or vagina to treat yeast infections. For mouth infections, it's available in liquid and tablet forms. For vaginal infections, it's available as a tablet insert. The oral medication is usually taken four to five times daily, while vaginal tablets are used just once daily.
Fluconazole and ketoconazole
Fluconazole (Diflucan®) and ketoconazole (Nizoral®) are oral antifungal medications that are very effective in treating yeast infections of the vagina and mouth. Vaginal yeast infections can be treated with a single oral dose, while mouth infections may require daily oral doses for up to two weeks, depending on how severe the infection is.
