Fluconazole, commonly known by its brand name Diflucan, is a widely used antifungal medication that has been a cornerstone in the treatment of various fungal infections for decades. As a triazole derivative, fluconazole works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes, ultimately leading to cell lysis and death. This mechanism of action makes it effective against a broad range of fungal pathogens.
Primary Uses of Fluconazole
Fluconazole is primarily used for the treatment of invasive fungal infections caused by susceptible strains of Candida and other fungi. Some of the most common indications for fluconazole include:
- Candidiasis, including vaginal yeast infections, oral thrush, and esophageal candidiasis
- Cryptococcal meningitis, a serious infection that affects the brain and spinal cord
- Coccidioidomycosis, a fungal infection caused by Coccidioides immitis or Coccidioides posadasii
- Histoplasmosis, a lung infection caused by Histoplasma capsulatum
Vaginal Yeast Infections
One of the most common uses of fluconazole is for the treatment of vaginal yeast infections, also known as vulvovaginal candidiasis. A single dose of fluconazole (150 mg) is often sufficient to clear the infection, making it a convenient and effective treatment option for women.
| Fungal Infection | Recommended Dosage |
|---|---|
| Vaginal yeast infections | 150 mg single dose |
| Oral thrush | 200-400 mg daily for 7-14 days |
| Cryptococcal meningitis | 400 mg daily for 2 weeks, followed by 200-400 mg daily for 8-10 weeks |
