When encountering widespread itching due to allergic skin reactions, the following measures can help alleviate symptoms: 1. **Avoid allergens**: Immediately identify and avoid substances that may be causing the allergy, such as foods, cosmetics, pollen, etc., to reduce further irritation and reaction. 2. **Topical medications**: Topical treatments such as calamine lotion or compound menthol cream can be applied to effectively relieve itching. If the skin becomes broken or weeping, a boric acid solution can be used for wet compresses, followed by the application of hydrocortisone butyrate cream or tacrolimus ointment for treatment. 3. **Oral medications**: When symptoms are severe or topical treatments are ineffective, oral medications may be taken as directed by a physician to relieve swelling and itching. 4. **Seek medical attention**: If allergic symptoms continue to worsen or cannot be relieved, prompt medical consultation is recommended for allergy testing to more accurately identify the allergen and receive targeted treatment under a doctor's guidance.
