What is fluconazole?

Fluconazole is an antifungal prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of esophageal candidiasis, oropharyngeal candidiasis, vaginal candidiasis, and cryptococcal meningitis.

Mucocutaneous candidiasis and cryptococcal meningitis are opportunistic infections. An opportunistic infection is an infection that occurs more frequently or is more severe in people with weakened immune systems -- such as those infected with HIV -- than in people with healthy immune systems.

Fluconazole can also be used "off-label" to prevent and treat other opportunistic infections of HIV infection. "Off-label" use refers to use of an FDA-approved medicine in a manner different from that described on the medicine label. Good medical practice and the best interests of a patient sometimes require that a medicine be used "off-label."
