Small white blisters on the body may be a sign of papular herpes. Most papules are seen in allergic dermatitis and eczema, so for this condition, it is possible that the skin damage is formed by allergic factors. Therefore, oral antihistamines are usually needed for antipruritus and anti-inflammation. Second-generation antihistamines such as levocetirizine hydrochloride, epinastine, imipramine, etc. can be taken orally. Topical glucocorticoid creams, such as Denide cream and hydrocortisone butyrate cream, can be applied topically as appropriate. If small blisters have ruptured and are accompanied by inflammatory exudative reactions, topical application of 3% boric acid solution can be used to effectively improve local exudative and inflammatory reactions.
