From the Research
The recommended treatment for jock itch is applying an over-the-counter topical antifungal cream, such as terbinafine 1% (Lamisil), to the affected area twice daily for 1-2 weeks. Effective options also include clotrimazole 1% (Lotrimin), miconazole 2% (Monistat), or butenafine 1% (Lotrimin Ultra) 2. Apply the cream to clean, dry skin, extending slightly beyond the rash, and continue treatment for at least one week after symptoms resolve to prevent recurrence. For severe or persistent cases, prescription-strength antifungals like ketoconazole 2% cream may be necessary. These medications work by disrupting the fungal cell membrane or inhibiting ergosterol synthesis, which is essential for fungal survival. While treating jock itch, keep the area clean and dry, wear loose cotton underwear, change clothes after sweating, and avoid sharing personal items to prevent reinfection or spreading the fungus to others. If symptoms worsen or don't improve after two weeks of treatment, consult a healthcare provider. Some key points to consider when treating jock itch include:
- The importance of treating the infection for an adequate duration to prevent recurrence
- The need to keep the affected area clean and dry to promote healing
- The potential for terbinafine to be more effective than other topical antifungals, such as ketoconazole, in achieving mycological and clinical cure 3
- The availability of various topical antifungal agents, including oxiconazole and sertaconazole, which have shown efficacy in treating dermatophytoses 4, 5 It is essential to note that while multiple studies support the use of various topical antifungals, the most recent and highest quality study should be prioritized when making a definitive recommendation 2.
