Contact dermatitis is considered when allergy occurs after applying adhesive tape. Contact dermatitis can be given topical glucocorticoid cream if there is no local oozing or blistering. It is recommended to apply topical medium-strength mometasone furoate cream in small amounts once in the morning and once in the evening. At the same time, oral antihistamines, such as desloratadine and levocetirizine, can be taken, and glucocorticoids need to be given in severe cases. If blistering and exudation occur, it is recommended not to use topical ointments first to avoid aggravating the rash, but to use saline, boric acid solution and other liquid wet compresses first, and then give topical ointments after exudation is reduced. For those with large lesions, blisters and exudation, it is recommended to give glucocorticosteroids intravenously or orally, and to reduce them quickly after improvement.
