When your child has a fish allergy and eats fish, your child's body reacts as if the fish causes harm. It fights back by setting off an allergic reaction. A mild reaction may include a few raised, red, itchy patches of skin (called hives). A severe reaction may cause hives all over, swelling in the throat, trouble breathing, nausea or vomiting, or fainting. This is called anaphylaxis (say "ANN-uh-fuh-LAK-suss"). It can be deadly.
A good way to prevent your child's allergic reaction is to avoid the foods that cause it. Fish might be found in Asian foods, sauces, and salad dressings that contain fish sauce or anchovies. It is also often found in imitation shellfish, such as crab. An allergy doctor or a dietitian may be able to help you understand which foods will be okay and what to avoid. Learn what to do if your child has a reaction.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
