From the Guidelines
Tinea corporis should be treated with oral antifungal medications, such as itraconazole 100 mg daily for 15 days, as it has shown a superior mycological cure rate of 87% compared to other treatments. When considering treatment options for Tinea corporis, it is essential to prioritize the most effective and recent evidence-based approaches. According to a study published in Pediatrics 1, oral agents like itraconazole have proven efficacious in treating most cases of T corporis. The study found that itraconazole, 100 mg, given orally once a day, was superior to griseofulvin, 500 mg, orally, once a day, when given for 15 days, with a mycological cure rate of 87% versus 57%, respectively. Some key points to consider when treating Tinea corporis include:
- The use of oral antifungal medications, such as itraconazole, for more severe or extensive infections
- The importance of avoiding skin-to-skin contact with people known to have lesions and not sharing personal items like towels or clothing
- Keeping the affected area clean and dry, and washing clothes, bedding, and towels in hot water to kill the fungus
- The potential for recurrence if treatment is stopped too early, emphasizing the need for completion of the full treatment course. Terbinafine appears superior for T tonsurans, but itraconazole is a more generally effective option for T corporis, as evidenced by the study 1.

From the Research
Treatment Options for Tinea Corporis
- Topical antifungal agents are the primary treatment for tinea corporis, with options including azoles, allylamines, and benzylamines 3
- Terbinafine is a commonly used topical antifungal agent that has been shown to be effective in treating tinea corporis, with clinical cure rates significantly higher than placebo 3
- Naftifine 1% has also been shown to be effective in achieving mycological and clinical cure in patients with tinea corporis 3
- Clotrimazole 1% has been found to be effective in achieving mycological cure in patients with tinea corporis 3
Duration and Application of Treatment
- Treatment duration for tinea corporis typically ranges from 1-4 weeks, with some studies showing that shorter treatment durations can be effective 4, 5
- The frequency of application can vary, with some studies using once-daily applications and others using twice-daily applications 5, 3
Systemic Therapy
- In some cases, systemic therapy may be necessary, particularly for extensive or resistant infections 4, 6
- Oral antifungal agents such as fluconazole, itraconazole, and terbinafine can be effective in treating tinea corporis, with varying dosing regimens and durations 6
Considerations and Precautions
- The presence of inflammation may necessitate the use of an agent with inherent anti-inflammatory properties or a combination antifungal/steroid agent 4
- Combination antifungal/steroid agents should be used with caution due to the potential for causing atrophy and other steroid-associated complications 4
