If you find anal itching you can use iodophor, but of course after using iodophor, you must continue to use warm salt water or warm water to rinse the iodophor locally, because if the iodophor exists for a long time, it may stimulate the surrounding skin and cause itching symptoms. However, local application of iodophor can effectively sterilize and avoid inflammatory stimulation causing itching. Therefore, if you find anal itching, you can use iodophor to rinse and then rinse with salt water to stop the itching to some extent. In most cases anal itching can be cleaned with warm water or warm salt water locally, and then take different medications for symptomatic treatment depending on the cause of the itching. If it is caused by perianal eczema, it is generally recommended to apply topical eczema removing creams. If it is due to inflammation, then topical application of anti-inflammatory drops will do.
