Topical ointments are the very main treatment for ringworm caused by fungal infections. Commonly used ointments include terbinafine cream, bifenazole cream, boutinafine hydrochloride cream, naftifine ketoconazole cream, sertaconazole nitrate cream, and compound ketoconazole ointment, all of which have very good results. In fact, in addition to proper treatment with creams, the duration of medication must be guaranteed and the course of treatment must be sufficient. For ringworm with superficial fungal skin infections, it is recommended to use the medication for at least 3 weeks, or even more than 1 month, and never to stop it prematurely on your own.
