Red dots and itchiness on the body after bathing are considered to be allergic diseases such as eczema or atopic dermatitis. In terms of clinical treatment, different treatments need to be chosen according to the mildness of the rash. If the rash is densely distributed and the itching is severe, compound glycyrrhetinic acid monoamine S sodium chloride injection with sodium thiosulfate injection can be ordered quietly. If the itching is significantly relieved, compound betamethasone injection can be injected intramuscularly to play an anti-allergic and immunosuppressive role, combined with chlorpheniramine maleate injection intramuscularly to strengthen the anti-allergic and anti-itch effectiveness. If the red dots are more scattered, you can choose oral as well as topical treatment only. Oral medications can be applied Olopatadine hydrochloride tablets, Epinastine hydrochloride capsules, and topical medications can be applied to Denide, hydrocortisone butyrate ointment to apply treatment.
