If you are allergic to the tape, you should see if there is any erythema or papules on the tape. If there is only erythema and itching, you can use topical halomethasone cream, hydrocortisone butyrate cream and alloxan to treat it and it will get better soon. If small blisters appear on the surface of the erythematous spots, you need to first use glyburide lotion and wait until the lesions dry up and become flaky before applying topical hormone ointment. If the itching is particularly severe, oral antihistamines such as cetirizine, loratadine, epalrestine, etc. can be taken. It is forbidden to use hot water to wash the area of the skin lesion, and it is better to apply cold compresses.
