The so-called papular urticaria is an allergic reaction associated with insect bites. It is advised not to wash the affected area with hot water; instead, bathing with lukewarm water is acceptable. Key preventive measures include managing the environment to avoid further insect bites and administering anti-allergy and anti-itch treatments. Oral medications such as loratadine syrup, prednisone acetate tablets, and vitamin C tablets are recommended. At the site of the skin lesions, topical medications such as fluticasone propionate, triamcinolone acetonide econazole cream, desonide cream, or antipruritic moisturizing cream can be used. If secondary symptoms such as ulceration and blister formation occur, it is necessary to enhance the cleanliness of the rash to prevent secondary bacterial infections by applying saline solution, Kangfuxin solution, or Phellodendron solution on the eroded areas. (Medication should be used under the guidance of a physician.)
