What is the best over-the-counter (OTC) medication for treating tinea cruris (jock itch)?

From the Guidelines

The best over-the-counter medication for treating tinea cruris is terbinafine 1% cream, which has been shown to have a mycological cure rate of approximately 94% when applied daily for 1 week 1. When treating tinea cruris, it is essential to choose an effective antifungal medication to reduce the risk of complications and improve quality of life.

• Key considerations for treatment include:
  • The medication's efficacy against dermatophyte fungi
  • The ease of application and patient compliance
  • The potential for side effects and interactions with other medications According to the available evidence, terbinafine 1% cream is a highly effective treatment option for tinea cruris, with a high mycological cure rate 1.
• Other over-the-counter alternatives, such as butenafine and clotrimazole, may also be effective, but terbinafine 1% cream has been shown to be highly effective in clinical studies 1. To use terbinafine 1% cream effectively, apply it to the affected area and surrounding skin daily for 1 week, as directed 1.
• It is also essential to practice good hygiene, such as washing and drying the affected area thoroughly, wearing loose-fitting cotton underwear, and avoiding sharing towels or clothing to prevent the spread of infection. If symptoms persist or worsen despite treatment, it is crucial to consult a healthcare provider for further evaluation and guidance.

From the Research

Treatment Options for Tinea Cruris

The best over-the-counter (OTC) medication for treating tinea cruris (jock itch) can be determined by examining the efficacy of various topical antifungal treatments.

• Terbinafine and naftifine are effective treatments for tinea cruris, with terbinafine showing significantly higher clinical cure rates compared to placebo 4.
• Clotrimazole 1% is also effective in achieving mycological cure, with a risk ratio of 2.87 compared to placebo 4.
• Azoles, such as clotrimazole, are a widely used class of antifungal medications, but their efficacy compared to other treatments is not well established 4.

Comparison of Treatment Duration and Efficacy

• A short treatment regimen of terbinafine 1% cream applied once daily for 7 days has been shown to be effective in achieving and maintaining mycological cure in patients with tinea corporis/cruris 5.
• Terbinafine has also been compared to clotrimazole for the treatment of tinea pedis, with terbinafine showing superior efficacy after a shorter treatment duration 6.
• The choice of treatment may depend on patient compliance, medication accessibility, and cost, with allylamines (such as terbinafine) offering a more convenient option due to their shorter treatment duration 7.

Oral vs. Topical Treatment

• Oral terbinafine has been shown to be effective in the treatment of tinea cruris/corporis, with a 1-week course of treatment resulting in significant clinical and mycological improvement 8.
• However, topical treatments are generally preferred for the treatment of tinea cruris due to their ease of use and lower risk of side effects.
