Itchy and peeling skin around the anus is mostly caused by perianal eczema and fungal infections that cause ringworm. If perianal eczema is the cause, erythromycin ointment can be applied to the affected area around the anus, preferably 3-5 times a day, and the area around the anus should be kept dry. In addition, since perianal eczema is associated with low autoimmune function, you can also apply hormone ointment. Wash the perianal area frequently with saline, and if possible, it is best to insist on a 15-20 minute sitz bath every day. If the ringworm is caused by a fungal infection, you should apply Dacronin ointment for treatment. Also to prevent other bacterial infections from occurring after peeling, you should keep the area around the anus hygienic and clean and insist on cleaning with potassium permanganate lotion. In addition to this, if it is caused by an allergic reaction, you can take oral paracetamol for treatment.
