From the Guidelines

Treatment for oral candidiasis should start with topical antifungals, such as miconazole buccal tablets or clotrimazole troches, for mild to moderate cases, while severe or resistant infections may require oral fluconazole. When considering treatment options, it's essential to assess the severity of the infection and the patient's underlying health conditions, such as HIV status or immunosuppression [ 1 ]. For patients with mild to moderate oral candidiasis, topical antifungals like miconazole buccal tablets (50-mg applied once daily to the mucosal surface) or clotrimazole troches (10-mg dissolved in the mouth 5 times daily) are effective [ 1 ]. In cases of more severe or resistant infections, oral fluconazole (200 mg on day one, followed by 100 mg daily) is often prescribed, with a treatment duration of at least 7-14 days [ 1 ]. It's crucial to address underlying factors contributing to the infection, such as uncontrolled diabetes, immunosuppression, or antibiotic use, to ensure successful treatment and prevent recurrence [ 1 ]. Additionally, good oral hygiene practices, including regular brushing, flossing, and cleaning dentures thoroughly, are essential during treatment [ 1 ]. In cases of fluconazole-refractory infections, alternative treatments like itraconazole solution, posaconazole suspension, or voriconazole may be considered [ 1 ]. Overall, the treatment approach should be tailored to the individual patient's needs, taking into account the severity of the infection, underlying health conditions, and potential resistance to antifungal medications. Key considerations in treatment include:

  • Topical antifungals for mild to moderate cases
  • Oral fluconazole for severe or resistant infections
  • Addressing underlying health conditions
  • Good oral hygiene practices
  • Alternative treatments for fluconazole-refractory infections.

From the FDA Drug Label

Nystatin Oral Suspension, USP, is indicated for the treatment of candidiasis in the oral cavity. The recommended dosage of SPORANOX ® (itraconazole) Oral Solution for oropharyngeal candidiasis is 200 mg (20 mL) daily for 1 to 2 weeks.

The treatment for oral candidiasis includes:

  • Nystatin Oral Suspension, USP 2
  • Itraconazole Oral Solution with a recommended dosage of 200 mg (20 mL) daily for 1 to 2 weeks 3

From the Research

Treatment Options for Oral Candidiasis

The treatment for oral candidiasis typically involves the use of antifungal agents, which can be administered topically or systemically. The choice of treatment depends on the severity of the infection and the patient's overall health.

  • Topical antifungal agents:
    • Nystatin 4, 5, 6
    • Miconazole 4, 5, 6
    • Clotrimazole 4, 5, 7
    • Amphotericin B 4, 5, 8
  • Systemic antifungal agents:
    • Fluconazole 4, 5, 6, 7, 8
    • Itraconazole 4, 5, 6
    • Ketoconazole 4, 6
    • Posaconazole 4, 5
    • Voriconazole 4, 5
    • Isavuconazole 4, 5
    • Echinocandins (e.g., caspofungin, micafungin, anidulafungin) 4, 5

Effectiveness of Treatment Options

Studies have shown that fluconazole and clotrimazole are effective in treating oral candidiasis, with similar effectiveness in terms of treatment 7. Nystatin and miconazole are also commonly used topical antifungal agents, but may require a longer treatment duration to eradicate the infection 5. Systemic antifungal agents, such as fluconazole, are often used to treat more severe or recalcitrant infections 6, 8.

Novel Approaches to Treatment

Novel approaches to antifungal therapy, such as the use of probiotics, are being explored 4. Additionally, new antifungal drugs, such as ibrexafungerp, and the use of antibodies, cytokines, and antimicrobial peptides, are being developed 5.
