CDC vulvovaginal candidiasis recurrent fluconazole dosing 2024

For recurrent vulvovaginal candidiasis (RVVC), usually defined as 3 or more symptomatic episodes within 12 months, the standard fluconazole approach for presumed Candida albicans is:
  1. Induction to achieve remission
    Fluconazole 150 mg orally on days 1, 4, and 7
    (equivalently, one dose every 72 hours for 3 doses).
  2. Suppressive maintenance
    Fluconazole 150 mg orally once weekly for 6 months.
The CDC permits 100 mg, 150 mg, or 200 mg dosing for each induction and weekly maintenance dose, but 150 mg is commonly used. CDC VVC guidance notes that suppression controls recurrence well but is not always curative once it is stopped.
Important
  • Confirm the diagnosis with vaginal microscopy/culture, particularly before long-term therapy, if symptoms persist, or if there is a concern for non-albicans Candida or azole resistance.
  • Avoid oral fluconazole in pregnancy. Pregnancy VVC is treated with a topical azole for 7 days instead.
  • Review drug interactions and risk factors, including liver disease, QT-prolonging drugs, warfarin, certain statins, and some diabetes medicines.
  • If culture-positive symptoms continue during maintenance, obtain susceptibility testing and seek gynecology or infectious-disease input.
Recent systematic-review evidence supports maintenance antifungal therapy but does not change this standard regimen (PMID 41845293).
