Wheat Allergy: Care Instructions

Overview

When you have a wheat allergy and you eat wheat, your body reacts as if the wheat is trying to cause 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, or fainting. It can also cause belly pain, nausea, vomiting, or diarrhea. This is called anaphylaxis (say "ANN-uh-fuh-LAK-suss"). It can be deadly.

Having a wheat allergy is not the same as having celiac disease or eating a gluten-free diet.

A good way to prevent an allergic reaction is to avoid the foods that cause it. Besides wheat breads, cereals, and pasta, wheat might be found in processed meats and sauces. An allergy doctor or a dietitian may be able to help you understand which foods might be okay and what to avoid. Learn what to do if you have a reaction.

How can you care for yourself at home?

During a mild reaction

• Take a nondrowsy antihistamine, such as loratadine (Claritin), as your doctor recommends. Be safe with medicines. Read and follow all instructions on the label.

During a severe reaction

• Give yourself an epinephrine shot. Keep it with you at all times. Make sure it has not expired.
• Call for emergency help. A severe allergic reaction can be life-threatening and is a medical emergency.

To prevent future reactions

• Avoid the foods that cause problems. And try not to use utensils or cookware that may have been in contact with food that you are allergic to.
• Teach your family members, coworkers, and friends what to do if you have a severe reaction to a food that you are allergic to.
• Wear medical alert jewelry that lists your allergies. You can buy this at most drugstores.
