Chronic urticaria is a complex type of urticaria, because 80% of chronic urticaria is difficult to find the exact cause. The treatment of urticaria should first try to help patients find the cause and remove the inducing factors, so that urticaria can be controlled or even cured. For example, if you are allergic to penicillin, it is recommended not to use penicillin. If you are allergic to seafood, don't eat seafood. This is a good way to treat urticaria. But the cause of chronic urticaria is difficult to find, because the cause is too complicated, which may be endogenous, autoimmune or idiopathic. In this case, there are usually the following four step-by-step treatment schemes:

1, conventional antiallergic therapy, medically called antihistamine therapy, oral antihistamines, loratadine, cetirizine, etc. , according to the regular dose. If the routine dose can't be controlled, upgrade to the second step;

2. If two or more antihistamines are used in combination, it can be doubled if there is no improvement. If you take 1 tablet normally, you can take 2 tablets. According to the general guidelines of international experts, antihistamines can be doubled to 2-4 times. Of course, some antihistamines have contraindications and indications under the guidance of doctors;

3, immunosuppressants, such as cyclosporine, tripterygium wilfordii, and even small doses of glucocorticoid;

4, biological agents, from the ladder treatment program to gradually control chronic urticaria.
