What is the recommended treatment for Candida (fungal infection) vaginitis?

Treatment of Candida Vaginitis

For uncomplicated Candida vaginitis, a single 150 mg oral dose of fluconazole or a 7-day course of intravaginal azole therapy (such as clotrimazole, miconazole, or butoconazole) is the recommended first-line treatment. 1, 2

Diagnosis Confirmation

• Diagnosis is suggested by:
  • Pruritus and erythema in vulvovaginal area
  • White discharge
  • Normal vaginal pH (≤4.5)
  • Positive wet preparation or Gram stain showing yeasts or pseudohyphae
  • Positive culture for yeast species

Treatment Options

Uncomplicated Vulvovaginal Candidiasis

Oral Therapy:

• Fluconazole 150 mg as a single oral dose 2
  • Provides 55% therapeutic cure rate (clinical + mycological)
  • Convenient single-dose regimen
  • May cause more gastrointestinal side effects than topical treatments

Intravaginal Azole Options:

• Clotrimazole 1% cream 5g intravaginally for 7-14 days 1
• Clotrimazole 100 mg vaginal tablet for 7 days 1
• Clotrimazole 100 mg vaginal tablet, two tablets for 3 days 1
• Clotrimazole 500 mg vaginal tablet, single application 1
• Miconazole 2% cream 5g intravaginally for 7 days 1
• Miconazole 200 mg vaginal suppository, one suppository for 3 days 1
• Butoconazole 2% cream 5g intravaginally for 3 days 1

Recurrent Vulvovaginal Candidiasis (RVVC)

RVVC is defined as ≥3 episodes per year and affects up to 10% of women 3.

Maintenance Therapy:

• Oral fluconazole (first-line): 150 mg weekly for 6 months 1
  • Improves quality of life in 96% of women
  • Recurrence may still occur in >63% after completing maintenance

Alternative Topical Maintenance:

• Clotrimazole, miconazole, or terconazole 1-3 times weekly 3
  • Twice weekly dosing most commonly utilized

For Non-albicans Candida Species:

• Nystatin or boric acid intravaginal preparations may be considered 3, 4
  • Nystatin shows consistent activity against non-albicans species (MIC90 of 4 mg/L) 4

Special Considerations

Pregnancy

• Only topical azole therapy should be used 1
• Avoid oral fluconazole due to association with spontaneous abortion 1
• Avoid boric acid in pregnancy 3

Treatment Failures

• For persistent symptoms after initial therapy:
  1. Confirm diagnosis with culture
  2. Consider non-albicans Candida species
  3. Consider longer duration of therapy (10-14 days)
  4. For C. glabrata infections, consider boric acid or nystatin 4

Clinical Pearls

• Oral and topical treatments show similar efficacy for uncomplicated cases 5
• Patient preference should be considered when selecting therapy
• Women with recurrent vaginitis have lower response rates to both oral and topical therapy 5
• The activity of antifungal drugs may be affected by vaginal pH, with some showing reduced efficacy at normal vaginal pH (4) compared to laboratory testing pH (7) 1
• Identification of Candida species may be important for treatment selection in recurrent cases 3
• Avoid empiric treatment without confirming diagnosis 6

Emerging Treatments

Oteseconazole (formerly VT-1161) shows promise for recurrent VVC with significantly lower recurrence rates compared to placebo (4% vs 52%) in clinical trials 1.
