Blisters are mainly blisters, and papular urticaria blisters need to be disinfected with iodophor and alcohol in a timely manner after they are broken, and applied externally with medications such as glycerite lotion and zinc oxide ointment. Pemphigus urticaria is caused by insect bites, and there are often pin-tail sized papules or blisters in the middle of the rash with intense itching. After the papular urticaria blisters are broken, they should be disinfected immediately by applying a disinfectant such as iodophor or alcohol to avoid bacterial infection. After disinfection, you can use glycerite lotion, zinc oxide ointment and other astringent anti-itching drugs to apply to eliminate the rash and itching. Patients with papular urticaria should pay attention to eat less spicy and stimulating food and do not drink alcohol. At night in spring and summer, try not to go to the grass, the garden where there are a lot of plants, and try to avoid scratching the rash. After the blisters are broken, avoid contact with dirty water or other dirty things to avoid infection. Patients with papular urticaria should go to the hospital in time and use the above drugs under the guidance of the doctor.
