The redness and swelling of the baby’s night mosquito bite can be relieved by topical and oral medication. 1. Topical medication: local topical antipruritic agents, such as glycerine lotion, zinc oxide powder, camphor cream or topical glucocorticosteroids, such as hydrocortisone butyrate cream, in order to anti-inflammatory and anti-itching, and to promote the lesions to subside. 2. Drug treatment: If the baby itching is obvious, can be combined with oral antihistamine drugs, such as cetirizine drops, diclofenac tadalafil dry suspension and so on. The above drugs are recommended to be used under the guidance of a doctor.
