    Food Allergies

    How Are Food Allergies Treated?

    The best way to avoid a reaction is to stay away from foods that cause it. Mild reactions usually will go away without treatment. For rashes, skin creams may ease discomfort, while antihistamines can help reduce itching and other symptoms.

    For more serious reactions, corticosteroids like prednisone will reduce swelling. In life-threatening situations, an epinephrine injection can start to reverse symptoms and is the only effective treatment.

    How Can I Be Prepared for an Allergic Reaction?

    Once you and your doctor have found which foods cause your allergies, stay away from them. But you need to maintain a healthy, nutritious diet. Ask your doctor to suggest foods that will give you the nutrients you need.

    You should also be aware of the ingredients in processed foods. Learn to read labels, and read them every time to know what you are about to eat. Your doctor, nurse, or a registered dietitian can help you learn how to read food labels to learn about hidden sources of food allergens.

    If you are prone to allergic reactions, ask your doctor to prescribe an epinephrine injection kit ("epi pen"), and carry two with you at all times.

    Don’t hesitate to use the epinephrine auto-injector pen if you show any symptom of anaphylaxis. The injection won’t hurt you and could save your life.

    Dial 911 even if you have injected yourself because the relief the pen may provide could be only temporary.
