Kids who are old enough can be taught how to give themselves the injection. If they carry the epinephrine, it should be nearby, not left in a locker or in the nurse's office. Wherever your child is, caregivers should always know where the epinephrine is, have easy access to it, and know how to give the shot. Staff at your child's school should know about the allergy and have an action plan in place.
Your child's medicines should be accessible at all times. Also consider having your child wear a medical alert bracelet. Every second counts in an allergic reaction.
If your child starts having serious allergic symptoms, like swelling of the mouth or throat or difficulty breathing, give the epinephrine auto-injector right away. Also give it right away if the symptoms involve two different parts of the body, like hives with vomiting. Then call and take your child to the emergency room. Your child needs to be under medical supervision because even if the worst seems to have passed, a second wave of serious symptoms can happen.
It's also a good idea to carry an over-the-counter OTC antihistamine for your child, as this can help treat mild allergy symptoms. Use antihistamines after — not as a replacement for — the epinephrine shot during life-threatening reactions. If allergy testing shows that your child has a shellfish allergy, the doctor will give you guidelines on keeping your child safe. To prevent allergic reactions, your child must not eat shellfish. Your child also must not eat any foods that might contain shellfish as ingredients.
Anyone who is sensitive to the smell of cooking shellfish should avoid restaurants and other areas where shellfish is being cooked. Always read food labels to see if a food contains shellfish. Manufacturers of foods sold in the United States must state whether foods contain any of the top eight most common allergens, including crustacean shellfish. The label should list "shellfish" in the ingredient list or say "Contains shellfish" after the list.
Some foods look OK from the ingredient list, but while being made they can come in contact with fish. This is called cross-contamination. Look for advisory statements such as "May contain fish," "Processed in a facility that also processes fish," or "Manufactured on equipment also used for fish. Manufacturers also do not have to list mollusk shellfish ingredients because mollusk shellfish clams, mussels, oysters, or scallops are not considered a major food allergen.
When labels say a food contains shellfish, they refer to crustacean shellfish. Contact the company to see about cross-contamination risk with mollusks. These toxins or poisons interfere with the function of nerve endings. Symptoms occur within 2 to 3 hours of eating contaminated food, and consist of tingling of the lips, tongue and throat, often followed by stomach upset, headache, fever, muscle aches and pains and in the case of ciguatera poisoning, sometimes changes in blood pressure and heart rhythm.

Home Patients Food allergy Allergic and toxic reactions to seafood. Varieties of seafood The major groups of seafood that can trigger allergic reactions are: Vertebrates fish with a backbone Fish including salmon, cod, mackerel, sardines, herring, anchovies, tuna, trout, haddock, John Dory, eels, rays. Allergies may occur to one or many foods Even though fish and shellfish live in the same place, the protein allergens present in one seafood group are generally considered to be very different to those in others.
Cross reactivity can be difficult to predict without testing Cross reactivity means that a similar protein is present in a range of different foods. Cooking can sometimes affect tolerance Seafood allergens are usually very heat stable and cannot easily be destroyed through cooking, although occasional individuals seem to tolerate tinned fish intensely heat treated , yet are unable to tolerate the same fish freshly cooked.
Delayed reactions to seafood Allergic symptoms after contact with seafood are usually within minutes, however, delayed type reactions and particularly exercise-induced anaphylaxis is occasionally observed, particularly after ingestion of shellfish such as oyster, abalone, squid and shrimp. Avoiding seafood groups is an important part of management Complete avoidance of one or more groups of seafood is often advised, yet this can be difficult.

Food allergy does not usually run in families Most of the time, children with food allergy do not have parents with food allergy.
