Ringworm is mainly treated with antifungal ointment, such as terbinafine ointment, which needs to be adhered to for more than 2 weeks, and antibiotic ointment, such as topical fusidic acid cream, if combined with bacterial infection. 1. If it is a simple fungal infection, you can apply terbinafine hydrochloride ointment, bifonazole cream, ketoconazole cream and other antifungal ointment to treat it, and you need to insist on using the medicine for more than 2 weeks or continue to use it for 1~2 weeks after the lesions subside, in order to prevent recurrence. 2. If there is a combination of bacterial infection and pus oozing from the skin lesions, it is also necessary to do a good job of disinfecting treatment. Povidone-iodine can be used to disinfect the lesions 2 to 3 times a day, and after that antibiotic drugs such as fusidic acid cream, erythromycin ointment, mupirocin ointment, etc. can be used together with the application of fusidic acid. It is recommended that patients with jock itch maintain personal hygiene and cleanliness on a daily basis, change clothes frequently, and treat under the guidance of a physician, do not blindly use medication on your own.
