The treatment of urticaria should begin with finding the cause. There are thousands of causes of urticaria, which are very complex, and in fact, about 80% of patients cannot find the cause, especially in chronic urticaria. In a minority of patients, even if the cause is found, it is difficult to avoid it. On the other hand, many urticaria will get better on its own after a period of time and may never develop again, or may develop after many years. Although there is no “cure” for urticaria, there are many effective anti-allergy medications available to treat it, and there is always a way to control the onset of the clumps and relieve the symptoms. The drugs commonly used to treat urticaria include: antihistamines that tend to produce drowsiness and drowsiness as a side effect such as paracetamol, diphenhydramine, anterol, ketamine, cytisine and ketotifen; new generation antihistamines that do not have drowsiness and drowsiness as a side effect such as cetirizine, keratan, epalrestin and petroleum jelly. Patients should visit a hospital and be treated under the guidance of a doctor. At present, Chinese medicine has greater advantages in the treatment of chronic urticaria, with fewer side effects, can be taken for a long time, and is less likely to recur after healing. For those with autoimmune urticaria, intractable urticaria, and severe urticaria, a combination of low-dose corticosteroids, immunosuppressants, and Chinese medicine can be used, and satisfactory results have been achieved.
