From the Guidelines
The recommended treatment for tinea versicolor includes both topical and oral antifungal medications. For mild to moderate cases, topical treatments are typically first-line and include selenium sulfide 2.5% shampoo (applied to affected areas for 10 minutes daily for 7 days), ketoconazole 2% shampoo (applied for 5 minutes daily for 3 days), or topical antifungal creams like clotrimazole, miconazole, or terbinafine (applied twice daily for 2-4 weeks). For extensive or recurrent cases, oral antifungal therapy may be necessary, with fluconazole 400mg as a single dose or 300mg weekly for 2-4 weeks being most common 1. Itraconazole 200mg daily for 5-7 days is an alternative oral option. Patients should be aware that skin discoloration may persist for weeks or months after successful treatment, even though the fungus is eliminated. For prevention of recurrence, especially in humid climates, maintenance therapy with selenium sulfide or ketoconazole shampoo used once or twice monthly can be effective. These treatments work by targeting the Malassezia yeast that causes the condition, disrupting its cell membrane or inhibiting ergosterol synthesis, which is essential for fungal cell wall integrity. Some key points to consider in the treatment of tinea versicolor include:
- The use of topical antifungal agents as first-line treatment for mild to moderate cases
- The consideration of oral antifungal therapy for extensive or recurrent cases
- The importance of patient education regarding the potential for persistent skin discoloration after successful treatment
- The role of maintenance therapy in preventing recurrence, particularly in humid climates. It's worth noting that the provided evidence does not directly address the treatment of tinea versicolor, but rather provides guidance on the treatment of other fungal infections, such as candidiasis and aspergillosis. However, the general principles of antifungal therapy can be applied to the treatment of tinea versicolor, and the recommended treatments are based on the most recent and highest quality evidence available 1.

From the Research
Treatment Options for Tinea Versicolor
The recommended treatment for Tinea versicolor includes:
- Topical antifungal therapy, which has a better safety profile and lower cost compared to systemic treatment 3
- Oral antifungal therapy, typically reserved for patients with extensive disease, frequent recurrences, or disease that is refractory to topical therapy 3
- Long-term intermittent prophylactic therapy for patients with frequent recurrence of the disease 3
Topical Antifungal Therapy
- Ketoconazole 2% shampoo has been shown to be effective and safe in the treatment of Tinea versicolor, with a clinical response rate of 73% and 69% for 3-day and 1-day treatment regimens, respectively 4
Oral Antifungal Therapy
- Fluconazole, itraconazole, and terbinafine are effective oral antifungal agents for the treatment of Tinea versicolor 5
- Fluconazole and ketoconazole have been shown to have similar efficacy and safety in the treatment of Tinea versicolor 6
- Oral fluconazole given at 300 mg once weekly for two weeks has been shown to be effective, tolerable, and safe in the treatment of Tinea versicolor, with a complete cure rate of 75% and mycologic cure rate of 77.5% 7
Selection of Antifungal Agents
- The selection of antifungal agents depends on several factors, including efficacy, safety, local availability, ease of administration, likelihood of compliance, and potential drug interactions of the antifungal agent 3
