What are the treatment options for vulvovaginitis?

Treatment Options for Vulvovaginitis

For vulvovaginitis treatment, topical azole agents or oral fluconazole 150mg as a single dose are equally effective first-line options for uncomplicated cases, while more complex cases require longer treatment durations and specialized approaches based on the causative organism. 1

Diagnosis and Classification

Before initiating treatment, proper diagnosis is essential:

• pH measurement: ≤4.5 suggests candidiasis, >4.5 suggests bacterial vaginosis or trichomoniasis 2
• Microscopy: Use 10% KOH preparation to visualize yeast and pseudohyphae 2
• Classification:
  • Uncomplicated vulvovaginitis: ~90% of cases, typically responds well to standard therapy 1
  • Complicated vulvovaginitis: ~10% of cases, includes severe/recurrent disease, non-albicans infections, or abnormal host factors 1

Treatment Options by Type

1. Uncomplicated Vulvovaginal Candidiasis

First-line options (equally effective with high-quality evidence) 1, 2:

• Topical azoles:

  • Clotrimazole 1% cream 5g intravaginally for 7-14 days
  • Miconazole 2% cream 5g intravaginally for 7 days
  • Miconazole 200mg vaginal suppository for 3 days
  • Tioconazole 6.5% ointment 5g intravaginally (single application)
  • Terconazole 0.4% cream 5g intravaginally for 7 days
  • Terconazole 0.8% cream 5g intravaginally for 3 days

• Oral therapy:

  • Fluconazole 150mg orally as a single dose 1, 3

2. Severe Vulvovaginal Candidiasis

For extensive vulvar erythema, edema, excoriation, and fissure formation:

• Extended topical therapy: 7-14 days of topical azole, OR
• Extended oral therapy: Fluconazole 150mg, two sequential doses (second dose 72 hours after initial) 1

3. Non-albicans Vulvovaginal Candidiasis (e.g., C. glabrata)

• First-line: Longer duration (7-14 days) of non-fluconazole azole therapy 1
• For unresponsive cases: Boric acid 600mg in gelatin capsule, vaginally once daily for 14 days 1
• Alternative options:
  • Nystatin intravaginal suppositories, 100,000 units daily for 14 days 1
  • Topical 17% flucytosine cream alone or with 3% amphotericin B cream daily for 14 days 1

4. Recurrent Vulvovaginal Candidiasis (≥4 episodes/year)

• Initial therapy: 7-14 days of topical azole or oral fluconazole
• Maintenance therapy: Fluconazole 150mg weekly for 6 months 1
• Alternative maintenance regimens 1:
  • Clotrimazole 500mg vaginal suppositories once weekly
  • Ketoconazole 100mg once daily
  • Itraconazole 400mg once monthly or 100mg once daily

Special Populations

Pregnancy

• Only topical azole therapies applied for 7 days are recommended 1, 2
• Oral azoles (fluconazole) should be avoided due to potential teratogenic effects

HIV-Infected Women

• Same treatment regimens as for non-HIV-infected women 1, 2
• May require longer treatment courses for severe cases

Women with Underlying Medical Conditions

• Women with uncontrolled diabetes or on corticosteroid treatment require more prolonged therapy (7-14 days) 1
• Efforts should be made to correct underlying conditions

Treatment Considerations and Pitfalls

Common Pitfalls

1. Misdiagnosis: Symptoms of vulvovaginal candidiasis (pruritus, irritation, vaginal soreness) are not specific for the infection 4
2. Inadequate treatment duration: Severe or complicated cases require longer treatment courses
3. Failure to identify non-albicans species: Culture is important for recurrent or complicated cases 5
4. Treating asymptomatic colonization: 10-20% of women normally harbor Candida without symptoms 1

Treatment Failure

If symptoms persist after initial treatment:

1. Verify diagnosis with microscopy or culture
2. Consider non-albicans Candida species
3. Evaluate for concurrent infections or conditions
4. Consider extended treatment regimens or alternative therapies 6

Follow-up

• Return for follow-up only if symptoms persist or recur 2
• For recurrent cases, evaluate for predisposing conditions
• Consider maintenance therapy for frequent recurrences

By following this evidence-based approach to vulvovaginitis treatment, clinicians can effectively manage both uncomplicated and complex cases, improving outcomes and reducing recurrence rates.
