What is the treatment for acute allergic urticaria?

The main treatment methods for acute allergic urticaria include: 1. **Medication therapy**: Oral antihistamines such as loratadine and cetirizine can effectively relieve allergic symptoms and typically work quickly with strong efficacy. If symptoms are severe, corticosteroids such as dexamethasone may be considered for intravenous infusion or intramuscular injection. 2. **Topical medications**: Application of topical agents such as calamine lotion or hydrocortisone ointment can help alleviate symptoms such as itching and swelling. These medications have antitoxic and anti-inflammatory effects and can effectively reduce skin discomfort caused by urticaria. 3. **Avoidance of allergens**: Removing the allergen is crucial for patients with acute allergic urticaria. Patients should avoid contact with substances that may trigger allergies, such as pollen, dust mites, and animal dander, to prevent recurrence of the condition. 4. **Symptomatic treatment**: Targeted symptomatic treatment should be provided according to specific symptoms presented by the patient, such as vomiting and diarrhea. Additionally, it is important to keep the skin clean and dry, and avoid scratching the affected areas to prevent secondary infection. 5. **Lifestyle adjustments**: Patients should also maintain healthy lifestyle and dietary habits, such as ensuring adequate sleep, engaging in appropriate physical activity, and following a light, easily digestible diet, to enhance immune function and promote recovery.
