Jock itch (a fungal infection of the groin) can sometimes persist even after using ketoconazole cream, especially if the infection is strong, not treated long enough, or if the area stays moist and sweaty. First, make sure you are applying the antifungal cream correctly; use it twice daily on the affected skin and continue for at least 2-4 weeks, even after symptoms improve. If ketoconazole has not worked, your doctor may switch you to a more effective antifungal cream such as luliconazole, sertaconazole, or terbinafine. Avoid using any creams that contain steroids, as they can worsen the infection. Keep the groin area clean and completely dry, wear loose cotton clothing, change undergarments daily, and avoid sharing towels. In more stubborn or widespread cases, oral antifungal medicines may be required under medical supervision. If itching and scabbing still persist despite proper treatment, it is best to consult a dermatologist to confirm the diagnosis and adjust treatment accordingly.
