How should allergic dermatitis be treated?

Local treatment of allergic dermatitis: if there is no exudation, calamine lotion can be used externally; If there is exudation, 2% ~ 4% boric acid solution or physiological saline can be used for cold compress and wet compress. After exudation is reduced, corticosteroid cream can be used externally, such as 0. 1% anti-inflammatory pine cream.

Systemic treatment: for patients with mild rash, antihistamines and calcium agents, such as chlorpheniramine, chlorhexidine, antongdine, terfenadine and sitamin, or intravenous injection of 10% calcium gluconate or sodium thiosulfate, or intravenous infusion of 5% ~ 10% glucose and vitamin C; If the rash is serious, corticosteroids can be used for a short time, such as oral prednisone or intramuscular dexamethasone or intravenous hydrocortisone.
