Fungal infections can occur in almost any part of your body. For example, you may end up suffering from a painful yeast infection, a fungal infection of your esophagus, a common fungal infection of the mouth called thrush or a cosmetic fungal infection of your toenails or fingernails. Fortunately, a medication called fluconazole can be taken to quickly clear up any type of fungal infection. The drug is available in many different formats, including powder, IV treatment or tablets in various doses. Make sure to discuss taking fluconazole with your doctor if you want to clear up your fungal infection once and for all!
