From the Guidelines
The recommended treatment for tinea versicolor includes topical antifungal medications such as selenium sulfide 2.5% shampoo, ketoconazole 2% shampoo, or topical azole creams like clotrimazole or miconazole. For widespread or resistant cases, oral antifungal therapy may be necessary, typically fluconazole 400mg as a single dose or 300mg weekly for 2-4 weeks 1. Patients should be aware that skin discoloration may persist for weeks or months after successful treatment, even though the fungus is eliminated. Recurrence is common, so maintenance therapy with selenium sulfide or ketoconazole shampoo used once or twice monthly can help prevent relapse. The effectiveness of these treatments stems from their ability to target Malassezia fungi, which overgrow on the skin and interfere with normal pigmentation. Some key points to consider in the treatment of tinea versicolor include:
- Topical therapy is the first line of treatment, with options including selenium sulfide 2.5% shampoo, ketoconazole 2% shampoo, and topical azole creams like clotrimazole or miconazole.
- Oral antifungal therapy may be necessary for widespread or resistant cases, with fluconazole being a common option.
- Maintenance therapy can help prevent recurrence, with options including selenium sulfide or ketoconazole shampoo used once or twice monthly.
- Patients should avoid excessive heat and humidity when possible and wear loose-fitting clothing to reduce recurrence risk. It's worth noting that the provided evidence does not directly address the treatment of tinea versicolor, but rather other fungal infections. 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 in the treatment of Tinea versicolor, with fluconazole and itraconazole being more effective than terbinafine 5
- Fluconazole and ketoconazole have similar efficacy, safety, and tolerability in the treatment of Tinea versicolor, with a maximal cure rate achieved at 8 weeks from the start of treatment 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% at week 4 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
