Anaphylaxis in Children
Medically reviewed by Drugs.com. Last updated on Jan 5, 2023.
is a life-threatening allergic reaction that must be treated immediately. Your child's risk for anaphylaxis increases if he or she has asthma that is severe or not controlled. Medical conditions such as heart disease can also increase your child's risk. It is important to be prepared if your child is at risk for anaphylaxis. Symptoms can be worse each time he or she is exposed to the trigger.
Steps to take for signs or symptoms of anaphylaxis:
- Immediately give 1 shot of epinephrine only into the outer thigh muscle. Even if your child's allergic reaction seems mild, it can quickly become anaphylaxis. This may happen even if your child had a mild reaction to the allergen in the past. Each exposure can cause a different reaction. Watch for signs and symptoms of anaphylaxis every time your child is exposed to a trigger. Be ready to give a shot of epinephrine. It is okay to inject epinephrine through clothing. Just be careful to avoid seams, zippers, or other parts that can prevent the needle from entering the skin.
- Leave the shot in place as directed. Your child's 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. Tell your adolescent never to drive himself or herself. Bring the used epinephrine shot to the emergency department.
Call 911 for any of the following:
- Your child has a skin rash, hives, swelling, or itching.
- Your child has trouble breathing, shortness of breath, wheezing, or coughing.
- Your child's throat tightens or his or her lips or tongue swell.
- Your child has trouble swallowing or speaking.
- Your child is dizzy, lightheaded, confused, or feels like he or she is going to faint.
- Your child has nausea, diarrhea, or abdominal cramps, or he or she is vomiting.
Seek care immediately if:
- Signs or symptoms of anaphylaxis return.
Contact your child's healthcare provider if:
- You have questions or concerns about your child's condition or care.
The following are some of the most common triggers in children:
- Milk, peanuts, tree nuts, eggs, shellfish and certain other kinds of fish, wheat, and soy
- Stings from bees, wasps, or fire ants
- Antibiotics, NSAIDs, or aspirin
- Exercise following exposure to another trigger, such as after your child eats a trigger food
Common signs and symptoms:
You may have any of the following within seconds to hours after exposure to a trigger:
- Trouble breathing, shortness of breath, wheezing, or coughing
- Throat tightening, swelling of the lips or tongue, or trouble swallowing
- Rash, hives, swelling, or itching
- Nausea, vomiting, diarrhea, or abdominal cramps
- Dizziness, lightheadedness, fainting, or confusion
- Sudden behavior changes or irritability
may include any of the following:
- Epinephrine is medicine used to treat severe allergic reactions such as anaphylaxis. It is given as a shot into the outer thigh muscle.
- Medicines such as antihistamines, steroids, and bronchodilators decrease inflammation, open airways, and make breathing easier.
- Oxygen may be needed if your child's blood oxygen level is lower than it should be. Your child may get oxygen through a mask placed over his or her nose and mouth or through small tubes placed in the nostrils.
The following list of medications are in some way related to or used in the treatment of this condition.
- 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, your child, and other family members 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 he or she eats. Tell your child to stop exercising right away if he or she starts to develop any signs or symptoms of anaphylaxis. Your child may first feel tired, warm, or have itchy skin. Hives, swelling, and severe breathing problems may develop if he or she 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 healthcare provider where to get these items.
- Identify and avoid known triggers. Read food labels for ingredients. Look for triggers in your child's environment.
- Ask about treatments to prevent anaphylaxis. Your child may need allergy shots or other medicines to treat allergies.
Follow up with your child's healthcare provider as directed:
Allergy testing may find allergies that can trigger anaphylaxis. Write down your questions so you remember to ask them during your visits.
