There is no such thing as a topical medication for lichen planus. The topical medicines for lichen planus are mainly antifungal medicines, including antifungal ointment such as ketoconazole ointment and antifungal lotion such as 2.5% selenium sulfide lotion, etc., and there are many kinds of them in the market. 1. Anti-fungal ointments include ketoconazole ointment, clotrimazole cream, miconazole ointment, terbinafine hydrochloride cream, butenafine cream and econazole cream. They are applied locally to the lesion area 2 to 3 times a day until the symptoms improve. 2. Anti-fungal lotion, such as 2.5% selenium sulfide lotion, can also be used externally for different parts of lichen planus. It is recommended that patients with lichen planus go to the hospital in time, under the guidance of the doctor to carry out regular treatment as early as possible, do not self-medication.
