Medical Care Clinical cure of an uncomplicated tinea cruris infection usually can be achieved using topical antifungal agents of the imidazole or allylamine family. [8] Consider patients unable to use topical treatments consistently or with extensive or recalcitrant infection as candidates for systemic administration of antifungal therapy, which has been proven safe in immunocompetent persons. [9] Prevention of tinea cruris reinfection is an essential component of disease management. Patients with tinea cruris often have concurrent dermatophyte infections of the feet and hands. Treat all active areas of tinea cruris infection simultaneously to prevent reinfection of the groin from other body sites. Advise patients with tinea pedis to put on their socks before their undershorts to reduce the possibility of direct contamination. Advise patients with tinea cruris to dry the crural folds completely after bathing and to use separate towels for drying the groin and other parts of the body.
