Fluconazole, commonly known by its brand name Diflucan, is a widely used antifungal medication that has proven effective in treating various fungal infections. One of the most commonly prescribed dosages is 200 mg fluconazole. This article aims to provide an in-depth understanding of 200 mg fluconazole, its uses, benefits, and potential side effects, as well as its role in managing fungal infections.
Fungal infections can affect various parts of the body, including the skin, nails, and internal organs. These infections are typically caused by fungi such as Candida, Aspergillus, and Cryptococcus. Fluconazole, a triazole antifungal agent, works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. This action disrupts the integrity of the fungal cell membrane, ultimately leading to the death of the fungal cells.

200 mg fluconazole is prescribed for a range of fungal infections, including:
- Vaginal yeast infections (vulvovaginal candidiasis)
- Oral thrush (oral candidiasis)

- Cryptococcal meningitis (infection of the membranes surrounding the brain and spinal cord)
- Candidemia (fungal infection in the blood)
