Allergies are an immune system reaction to a substance called an allergen. Your child's immune system sees the allergen as harmful and attacks it. An allergic reaction can be mild or life-threatening. A life-threatening reaction is called anaphylaxis. Anaphylaxis is a sudden, life-threatening reaction that needs immediate treatment.

DISCHARGE INSTRUCTIONS:

Call 911 for signs or symptoms of anaphylaxis,

such as trouble breathing, swelling in your child's mouth or throat, or wheezing. Your child may also have itching, a rash, hives, or feel like he or she is going to faint.

Return to the emergency department if:

• Your child has tingling in his or her hands or feet.
• Your child's skin is red or flushed.

Contact your child's healthcare provider if:

• You have questions or concerns about your child's condition or care.

Medicines:

Your child may need any of the following:

• Antihistamines help decrease itching, sneezing, and swelling. Your child may take them as a pill or use drops in his or her nose or eyes.
• Decongestants help your child's nose feel less stuffy.
• Steroids decrease swelling and redness.
• Topical treatments help decrease itching or swelling. Your child may also be given nasal sprays or eyedrops.
• Epinephrine is medicine used to treat severe allergic reactions such as anaphylaxis.
• Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell the provider if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Steps you and your child need to take for signs or symptoms of anaphylaxis:

• Immediately give 1 shot of epinephrine only into the outer thigh muscle.
• Leave the shot in place as directed. Your healthcare provider may recommend you leave it in place for up to 10 seconds before you remove it. This helps make sure all of the epinephrine is delivered.
• Call 911 and go to the emergency department, even if the shot improved symptoms. Teach your adolescent not to drive himself or herself. The used epinephrine shot should be brought to the emergency department.

Safety precautions if your child is at risk for anaphylaxis:

• Keep 2 shots of epinephrine with your child at all times. Your child may need a second shot, because epinephrine only works for about 20 minutes and symptoms may return. Your child's healthcare provider can show you and family members how to give the shot. Depending on your child's age, the provider may also teach your child how to give the shot. Check the expiration date every month and replace it before it expires.
• Create an action plan. Your healthcare provider can help you create a written plan that explains the allergy and an emergency plan to treat a reaction. The plan explains when to give a second epinephrine shot if symptoms return or do not improve after the first. Give copies of the action plan and emergency instructions to family members, work and school staff, and daycare providers. Show them how to give a shot of epinephrine.
• Help your child be careful when he or she exercises. If your child has had exercise-induced anaphylaxis, do not let him or her exercise right after eating. Have your child stop exercising right away if he or she starts to develop any signs or symptoms of anaphylaxis. He or she may first feel tired, warm, or have itchy skin. Hives, swelling, and severe breathing problems may develop if your child continues to exercise.
• Have your child carry medical alert identification. Have your child wear medical alert jewelry or carry a card that explains the allergy. Ask your child's healthcare provider where to get these items.
• Inform all healthcare providers of the allergy. This includes dentists, nurses, doctors, and surgeons.

Manage your child's allergies:

• Use nasal rinses as directed. If your child is old enough, have him or her rinse with a saline solution daily. This will help clear allergens out of your child's nose. Use distilled water if possible. You can also boil tap water and let it cool before your child uses it. Do not let your child use tap water that has not been boiled.
• Keep your child away from cigarette smoke. Allergy symptoms may decrease if your child is not around smoke. Talk to your adolescent about not smoking. Nicotine and other chemicals in cigarettes and cigars can cause lung damage. Ask your adolescent's healthcare provider for information if he or she currently smokes and needs help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your adolescent's healthcare provider before he or she uses these products.

Help your child prevent an allergic reaction:

• Do not let your child go outside when pollen counts are high if he or she has seasonal allergies. Your child's symptoms may be better if he or she goes outside only in the morning or evening. Use your air conditioner, and change air filters often.
• Help your child avoid dust, fur, and mold. Dust and vacuum your home often. Your child may want to wear a mask during vacuuming. Keep pets in certain rooms, and bathe them often. Use a dehumidifier (machine that decreases moisture) to help prevent mold.
• Do not let your child use products that contain latex if he or she has a latex allergy. Have your adolescent use nonlatex gloves if he or she needs gloves for work. Always tell healthcare providers about your child's latex allergy.
• Have your child avoid areas that attract insects if he or she has an insect bite or sting allergy. Areas include trash cans, gardens, and picnics. Do not let your child wear bright clothing or strong scents when he or she will be outside.
• Help your child prevent an allergic reaction caused by food. Your child may have a reaction if your child's food is not prepared safely. For example, your child could be served food that touched your child's trigger food during preparation. This is called cross-contamination. Kitchen tools can also cause cross-contamination. Tell your child's school officials or daycare providers about the allergy. They may need to prepare your child's food in a separate part of the kitchen to prevent cross-contamination.

Follow up with your child's healthcare provider as directed:

Write down your questions so you remember to ask them during your visits. When your child has an allergic reaction, write down everything he or she was exposed to in the 2 hours before the reaction. Take that information to your next visit.
