Treatment of Thrush
For oral thrush, clotrimazole troches (10 mg 5 times daily) or fluconazole (100-200 mg daily) are the recommended first-line treatments, with selection based on severity of infection. 1
Oral Thrush Treatment Algorithm
Mild Oral Thrush
- Clotrimazole troches: 10 mg 5 times daily for 7-14 days 1
- Miconazole mucoadhesive buccal 50-mg tablet applied to the mucosal surface over the canine fossa once daily for 7-14 days 1
- Nystatin suspension or pastilles four times daily 2
Moderate to Severe Oral Thrush
- Fluconazole: 100-200 mg daily for 7-14 days 1
- For palliative care patients, a single dose of fluconazole 150 mg has shown 96.5% improvement in signs and symptoms, offering reduced pill burden 3
Fluconazole-Refractory Disease
- Itraconazole solution: 200 mg once daily for up to 28 days 1
- Posaconazole suspension: 400 mg twice daily for 3 days, then 400 mg daily for up to 28 days 1
- Voriconazole: 200 mg twice daily 1
- Amphotericin B oral suspension: 100 mg/mL 4 times daily 1
Patients Unable to Tolerate Oral Therapy
- Intravenous fluconazole: 400 mg (6 mg/kg) daily 1
- Intravenous echinocandin (caspofungin, micafungin, or anidulafungin) 1
- Intravenous amphotericin B deoxycholate: 0.3 mg/kg daily (less preferred due to toxicity) 1
Vaginal Thrush Treatment
Topical Treatments
- Clotrimazole cream: insert one applicatorful into the vagina at bedtime for 3 days in a row 4
- For external symptoms: apply small amount of cream to affected area twice daily for up to 7 days 4
- Other intravaginal options include:
Oral Treatment
- Fluconazole 150 mg as a single oral dose is effective for uncomplicated vaginal thrush 5
- During pregnancy, topical imidazoles are preferred over nystatin 6
- Pregnancy treatment should last 7 days rather than shorter courses used in non-pregnant women 6
Special Considerations
Denture-Related Candidiasis
- Disinfect dentures in addition to antifungal therapy 1
- Remove dentures at night and clean thoroughly 1
HIV-Infected Patients
- Antiretroviral therapy is strongly recommended to reduce recurrent infections 1
- May require longer treatment courses or higher doses of antifungal medications 1
- Fluconazole resistance may develop, especially in patients with low CD4 counts on fluconazole prophylaxis 7
Recurrent Infections
- For recurrent oral thrush: fluconazole 100 mg three times weekly for chronic suppressive therapy 1
- For recurrent vaginal thrush: consider longer treatment duration and addressing underlying factors 8
Treatment Duration
- Continue treatment until clinical resolution of symptoms 1
- For oral thrush: typically 7-14 days 1
- For vaginal thrush: 3-7 days for most topical treatments; single dose for oral fluconazole 4, 5
