Eczema on the neck in summer can be treated with general therapy and medication to improve the symptoms. As there are many folds at the neck, sweat will be stored in the folds when it is hot in summer, and the folds are easy to be impregnated when they are wet for a long period of time, which may cause eczema or aggravate the symptoms of eczema. Therefore, it is necessary to try to be in a dry and refreshing environment in summer to reduce sweating and keep the neck dry, and at the same time, don’t wear irritating clothes and avoid sun exposure, etc. If the skin lesions are mainly erythema and papules without exudation, zinc oxide ointment or glycerite lotion can be used externally, and glucocorticoid ointment such as hydrocortisone butyrate cream and mometasone furoate cream can also be used externally. If the skin with erythema, papules, accompanied by oozing, vesicles, itching, can be used externally boric acid solution wet compresses; to be dry lesions, no oozing, and then externally glucocorticoid ointment. When the itching symptoms are serious, oral antihistamines such as loratadine and cetirizine can be taken as prescribed by the doctor; when the symptoms are serious, glucocorticosteroids such as prednisone and immunosuppressants such as cyclosporine can be applied systematically under the guidance of the doctor to improve the symptoms. It is recommended that patients with eczema on the neck in the summer go to a regular hospital in time, and standardize the treatment under the guidance of the doctor.
