Treatment of Severe Fungal Vaginitis
For severe vulvovaginal candidiasis, use either 7-14 days of topical azole therapy OR fluconazole 150 mg orally in two sequential doses (second dose 72 hours after the initial dose). 1
Definition and Recognition
Severe vulvovaginal candidiasis is characterized by extensive vulvar erythema, edema, excoriation, and fissure formation. 1 These patients have lower clinical response rates to short-course therapy compared to uncomplicated cases. 1
Primary Treatment Approach
First-Line Options:
Option 1: Extended Topical Azole Therapy (7-14 days) 1
- Clotrimazole 1% cream 5g intravaginally for 7-14 days 2
- Butoconazole 2% cream 5g intravaginally for 7-14 days 2
- Other topical azoles for extended duration 1
Option 2: Sequential Oral Fluconazole 1
- Fluconazole 150 mg orally, first dose
- Second dose of fluconazole 150 mg orally 72 hours later 1
- This two-dose regimen achieves significantly higher clinical cure rates in severe vaginitis (P=0.015) 3
Evidence Supporting Extended Therapy
The two-dose fluconazole regimen demonstrates superior outcomes compared to single-dose therapy in severe cases. 3 At day 14 evaluation, the sequential dosing achieved significantly better clinical cure rates, with higher clinical and mycologic responses persisting at day 35. 3 Single-dose therapy, while effective for uncomplicated cases (94% clinical cure rate), 4 is insufficient for severe presentations. 1
Special Considerations
Non-albicans Species:
If non-albicans Candida (particularly C. glabrata) is suspected or confirmed, multivariate analysis shows significantly reduced response regardless of therapy duration. 3 For these cases:
- Use 7-14 days of non-fluconazole azole therapy as first-line 1
- If recurrence occurs, boric acid 600 mg in gelatin capsule vaginally once daily for 14 days (approximately 70% eradication rate) 1, 2
Pregnancy:
Only topical azole therapies applied for 7 days should be used in pregnant women—oral fluconazole is contraindicated. 1, 2
Immunocompromised Patients:
Women with uncontrolled diabetes or receiving corticosteroid treatment require the full 7-14 day conventional antimycotic treatment course. 1 Efforts to correct modifiable conditions should be made concurrently. 1
Common Pitfalls to Avoid
- Do not use single-dose fluconazole for severe vaginitis—this is only appropriate for uncomplicated cases. 1
- Do not use oil-based creams/suppositories with latex barrier contraception—they weaken condoms and diaphragms. 2
- Do not assume all cases are C. albicans—10-20% of recurrent cases involve non-albicans species requiring different management. 1
Safety Profile
Fluconazole is generally well tolerated. 5 In the single-dose vaginitis studies, the most common side effects were headache (13%), nausea (7%), and abdominal pain (6%), with most being mild to moderate. 5 The two-dose regimen for severe cases was similarly well tolerated without serious adverse effects. 3
Follow-Up
Follow-up visits are only necessary if symptoms persist or recur within 2 months. 2 If symptoms do not improve with the extended regimen, obtain vaginal cultures to identify the specific Candida species and guide further therapy. 1
