Pemphigus urticaria is most common in children and is a form of insect bite dermatitis. It can be cured by general treatment and medication, but the specific efficacy varies from person to person. 1. General treatment: Attention should be paid to protection in daily life and prevention of mosquitoes when going out. After lesions appear, avoid scratching and keep the affected area clean and dry. 2. Medication (1) Local treatment: glucocorticoid drugs such as budesonide ointment and dexamethasone ointment are often used to apply locally for mild symptoms. (2) Systemic treatment: those with itching can use antihistamines such as cilitrazine and loratadine for systemic treatment. Patients with generalized lesions and severe allergies can be treated with short-term oral glucocorticosteroids, such as methylprednisolone. The use of specific drugs should be under the guidance of a doctor. If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
