If the face is severely allergic, if the reaction is obvious and accompanied by obvious exudation and edema, intravenous glucocorticoids can be administered in a timely manner, such as intravenous dexamethasone or intravenous hydrogenated prednisone, etc. for anti-inflammatory treatment, while local topical saline or cold compresses with 3% boric acid solution can be applied. Oral antihistamines can also be used for antiallergic treatment, such as oral diphenhydramine or oral levocetirizine hydrochloride or epothilone. If the exudative reaction is not too obvious, intravenous glucocorticoids can also be temporarily dispensed with and oral antihistamines can be administered directly. Topical glucocorticoids can also be applied topically for a short period of time, such as hydrocortisone butyrate cream or topical skin ointment, and tacrolimus ointment. If infection is also present, anti-infective treatment is also required.
