Persistent jock itch (Tinea Cruris) despite treatment usually means the infection is not fully cleared or is being worsened by moisture, tight clothing, or use of mixed creams. You should continue a proper antifungal treatment for at least 2-4 weeks with a stronger antifungal cream like luliconazole or sertaconazole (as advised by a doctor), and sometimes a longer course of oral antifungal medicine may be needed instead of once-weekly dosing. Keep the area clean and completely dry, wear loose cotton underwear, avoid sharing towels, and change clothes after sweating. Very importantly, avoid steroid-containing creams, as they can make the infection stubborn and recurrent. If it still does not improve, consult a doctor for proper examination and possibly tests to confirm the diagnosis and adjust treatment.

Ringworm that is not improving despite tablets and creams is often due to the use of steroid-containing combinations like Dermikem OC, which should be stopped immediately, as they suppress the rash but worsen the fungal infection and cause resistance. The correct treatment is to use a plain antifungal cream (such as terbinafine, luliconazole, or ketoconazole) applied regularly for at least 3-4 weeks and continued for 1-2 weeks after the skin looks normal, along with a properly supervised course of oral antifungal medication prescribed by a dermatologist (the dose and duration may need adjustment). It is very important that both you and your wife take treatment at the same time, follow strict hygiene by keeping the area clean and dry, wearing loose cotton clothes, washing clothes and undergarments in hot water, and avoiding sharing towels to prevent reinfection. Since your infection has lasted 6 months and is not responding, a dermatologist consultation is essential for proper evaluation and complete treatment.
