An allergic reaction is usually mild, causing hives or whelps (urticaria) and itching. Hives are large red areas that are raised and usually come and go over four to six hours, disappearing in one area and popping up in another. Hives usually only last a few days, but may last weeks, even if your child is not being exposed to what he is allergic to anymore. You can use an over the counter antihistamine, such as Benadryl to treat hives.
