Fluconazole is an antifungal medication used for a number of fungal infections.[5] This includes candidiasis, blastomycosis, coccidioidomycosis, cryptococcosis, histoplasmosis, dermatophytosis, and tinea versicolor.[5] It is also used to prevent candidiasis in those who are at high risk such as following organ transplantation, low birth weight babies, and those with low blood neutrophil counts.[5] It is given either by mouth or by injection into a vein.[5]

Common side effects include vomiting, diarrhea, rash, and increased liver enzymes.[5] Serious side effects may include liver problems, QT prolongation, and seizures.[5] During pregnancy it may increase the risk of miscarriage while large doses may cause birth defects.[6][5] Fluconazole is in the azole antifungal family of medication.[5] It is believed to work by affecting the fungal cellular membrane.[5]

Fluconazole was patented in 1981 and came into commercial use in 1988.[7] It is on the World Health Organization's List of Essential Medicines.[8] Fluconazole is available as a generic medication.[5] In 2022, it was the 160th most commonly prescribed medication in the United States, with more than 3 million prescriptions.[9][10]
