Perianal eczema is a common anorectal condition that manifests clinically as perianal dampness with itching. The treatment requires a multi-pronged approach: internal medication, external application and sitz bath. The internal medication can be either Desloratadine tablets or Epastine tablets, one Desloratadine tablet every day during the day and two Epastine tablets every night, which play an anti-allergic and anti-itching role. The perianal area can be coated with boric acid zinc oxide ice ointment, which plays a role in collecting moisture and relieving itching. The medicine for the sitz bath can be chosen from Jieer Yin or Gynecological Jie and other herbal medicines that have the ability to clear heat, dry dampness and relieve itching. Half a bottle is used each time, and after diluting with about three hundred milliliters of water, the buttocks are soaked in it and generally sit in the bath for about fifteen minutes. After seven to ten days of medication, the symptoms will generally improve gradually. During the period of medication, pay attention to avoid eating beef, mutton and other inflammable hair products.
