In most cases, anal itch can be treated by:
Thoroughly but gently drying the anal area after every bowel movement, using unscented toilet paper, a clean cloth towel or a hair dryer if necessary.
Dusting the anal area with nonmedicated talcum powder between bowel movements, or laying a clean square of cotton gauze against the anus to absorb any excess moisture.
Resisting the urge to scratch, no matter how itchy the area becomes. The itch will pass, or at least decrease in intensity, over a short time, but the more you scratch, the longer it will take for the itching to go away.
Applying topical remedies such as zinc oxide or hydrocortisone ointment (1 percent) on a regular schedule, or as needed, to help you avoid scratching.
Wearing soft cotton gloves while in bed if you scratch at night or in your sleep.
