By blocking the development of membranes that cover fungal cells, fluconazole stops the growth of fungus. It is highly successful at treating Candida infections that affect the genitalia, blood, lungs, throat, and oral cavity. Fluconazole is an effective treatment for several common infections, including vaginal thrush, which is an infection brought on by an excess of the yeast Candida albicans. In patients whose immune systems are weakened by conditions including HIV/AIDS, chemotherapy, and bone marrow transplants, diflucan may also be used to prevent fungal infections. Such individuals are susceptible to internal fungal infections as a result of their immune system's inability to combat infectious germs, and prophylaxis using antifungal drugs, such as Diflucan, is frequently necessary due to the substantial risks associated with these infections.

When the body's level of the medication stays constant during the course of treatment, diflucan is more effective. Patients are advised to take it at roughly the same time each day for this reason. One dose of Diflucan per day is typical. It can be taken before or after meals because eating does not affect its effectiveness. While some infections, like vaginal thrush, typically go away with a single 150 mg dose, other infections might need a lengthier course of therapy that can last up to a few weeks. Both adults and kids can safely use diflucan. Even if you are no longer having any symptoms, it is crucial to continue taking Diflucan for the duration of the treatment.
