What is Fluconazole?

What is Fluconazole used for?

Fluconazole is used to prevent and treat candidiasis. This condition is caused by a fungal infection with one of the many types of the 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, oesophagus, lungs, and blood.

How does Fluconazole work?

Fluconazole belongs to a class of drugs called triazole antifungals.

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.
