From the Guidelines
Terbinafine is the first-line agent for the treatment of jock itch (tinea cruris). When considering the treatment options for jock itch, several factors such as efficacy, safety, and patient compliance are taken into account.
- The treatment goals are to achieve a mycological cure, reduce symptoms, and prevent recurrence.
- Topical antifungal medications are generally preferred over oral agents for initial treatment due to their favorable safety profile and effectiveness.
- Among the options provided, terbinafine stands out due to its high mycological cure rate of approximately 94% when used as a 1% cream applied daily for 1 week, as noted in the study published in Pediatrics 1.
- Other options like itraconazole, miconazole, and metronidazole may be considered in specific cases or when first-line treatments are not effective or appropriate.
- Itraconazole, for example, has been shown to be effective in adults for treating tinea cruris, especially when oral therapy is preferred or necessary 1.
- Miconazole and other azole antifungals are also effective but may not offer the same level of efficacy as terbinafine for tinea cruris.
- Metronidazole is not typically used for the treatment of fungal infections like jock itch, as it is primarily an antibacterial and antiprotozoal agent.
- The choice of treatment should be guided by the most recent and highest quality evidence, patient factors, and the potential for side effects or interactions.
- In the context of real-life clinical practice, terbinafine's efficacy and safety profile make it a preferred first-line option for the treatment of jock itch, as supported by the study published in Pediatrics 1.

From the Research
First-Line Agents for Jock Itch
The following are considered first-line agents for the treatment of jock itch (tinea cruris):
- Terbinafine 4, 5, 6, 7, 8
- Topical antifungals such as azoles (e.g. clotrimazole) and allylamines (e.g. naftifine) 6
Comparison of Treatment Options
Studies have compared the efficacy of different treatment options for tinea cruris:
- Terbinafine has been shown to be effective in achieving clinical and mycological cure 6, 8
- Combination therapy with oral terbinafine and itraconazole may be an effective and safe therapeutic strategy 5
- Topical antifungals such as clotrimazole and naftifine have also been shown to be effective 6
