Why it's used
Fluconazole is used to prevent and treat candidiasis. This condition is caused by infection with one of the many types of the fungus Candida. Examples of candidiasis include vaginal yeast infection, as well as oral yeast infection (thrush).
Candidiasis can also cause infections on other parts of your body, including your throat, esophagus, lungs, and blood. People who have had bone marrow transplants may be treated with fluconazole to prevent candidiasis. This is because their immune systems are weakened, which makes them more likely to become infected with a severe form of candidiasis.
Fluconazole is also used to treat meningitis (infection of the brain and spinal cord) that’s caused by the fungus Cryptococcus.

Fluconazole works by blocking the ability of the fungi Candida and Cryptococcus to reproduce. For people with infections from these fungi, this drug helps to get rid of the infection. For people at higher risk of candidiasis, it helps to prevent infection.
