If a child has chronic urticaria, he or she will often have recurrent episodes of hives that are difficult to heal. In this case, parents can deal with the situation in the following ways: 1. Have the child tested for allergens. This is because allergen testing helps the child to find the specific factors that cause the allergy. For example, if the child is allergic to fish and shrimp protein, the child should avoid eating fish and shrimp as much as possible. If it is caused by exposure to pollen, the child should be careful to avoid pollen. Therefore, allergen testing is very important and can be targeted to guide the child to avoid allergens; 2. Anti-allergy treatment should be given to the child. Commonly used anti-allergy drugs mainly include glucocorticoids and antihistamines. Glucocorticoids can be used prednisone, while antihistamines are often used loratadine or cetirizine syrup.
