Urticaria has many causes, including the long-term effects of bright light and the environment, as well as the consumption of foods that are prone to allergies, which are common causes.
However, according to clinical experience, urticaria is a typical allergic disease, mostly related to contact allergens, so it is difficult to completely cure.
Only by completely cutting off the allergen and finding the cause can the disease be treated fundamentally, but many people do not know the cause of urticaria, so it is impossible to effectively control the disease.
Let's introduce, what is the cause of urticaria?
First, insect bite rash

Second, drug factors
Drugs such as penicillin, ampicillin, vancomycin, antipyretics, and vaccines can cause the child's process, resulting in rashes and rubella, which are common causes.
There may be no rash on the first to second day of treatment, and on the third day the rash and wheal appear, and drug-induced urticaria needs to be suspected.
At this time, it should be stopped immediately, it is recommended to use anti-allergic drugs to improve the disease, of course, it is best to do a drug allergen test, to understand which drugs can not be eaten, so as to eliminate the cause of this disease.
