Most patients with clinical urticaria can be eradicated after regular treatment. The vast majority of patients with urticaria are often treated with oral antihistamines for 5-7 days and then the urticaria itself can be effectively controlled without recurrent attacks. However, there are many patients with chronic spontaneous urticaria and patients with induced urticaria. These patients often have recurring episodes of urticaria in the clinic. Many patients with induced urticaria are not able to completely stop the urticaria after regular treatment. This is because the cause of urticaria in such patients is often related to the fact that they have an allergic constitution. Such patients can consider taking antihistamines for a long time, as well as Chinese herbal medicine to systematically regulate. If you can effectively control it, you can slowly reduce the amount, and you must try to reduce the exposure to allergens.
