Fluconazole Dosing for Vaginal Candidiasis

Treatment Recommendations

The Infectious Diseases Society of America recommends a single 150 mg oral dose of fluconazole as the first-line treatment for uncomplicated vaginal candidiasis, with clinical cure rates of over 90% 1
For severe acute vaginal candidiasis, the recommended treatment is fluconazole 150 mg given every 72 hours for a total of 2-3 doses, which has shown superior clinical and mycological cure rates compared to single-dose therapy 1, 2
In cases of C. glabrata infection unresponsive to oral azoles, the first-line treatment option is topical intravaginal boric acid in gelatin capsules, 600 mg daily for 14 days 1, 3
For recurrent vulvovaginal candidiasis, initial induction therapy with topical agent or oral fluconazole for 10-14 days, followed by maintenance therapy with fluconazole 150 mg weekly for 6 months, has been shown to keep 90.8% of women disease-free at 6 months 1, 2

Diagnosis of vaginal candidiasis should be confirmed by wet mount preparation with saline and 10% potassium hydroxide to demonstrate yeast or hyphae before starting treatment 1, 3
Normal vaginal pH (4.0-4.5) is typically present with candida infections, and for negative wet mount findings, vaginal cultures for Candida should be obtained 1

Azole-resistant C. albicans infections are extremely rare but can develop following prolonged azole exposure 1
Treatment of vulvovaginal candidiasis should not differ based on HIV status 1
