How is anaphylaxis diagnosed in a child?
A healthcare provider can often diagnose anaphylaxis based on a health history alone. The healthcare provider will look at the following to make a diagnosis:
- Any known allergies
- Exposure to known or possible allergens
- Description of symptoms
- Physical exam, including blood pressure
- Blood test results, in some cases
How is anaphylaxis treated in a child?
Anaphylaxis is a medical emergency that needs to be treated right away. Your child will get a dose or shot of epinephrine through an autoinjector. This will help stop the bad reaction caused by the allergen. A dose of epinephrine should be given right after the exposure. Epinephrine can help stop or reverse the allergic reaction.
Always keep 2 epinephrine autoinjectors with your child. Sometimes your child will need 2 doses of epinephrine for more severe anaphylactic reactions. Five to 15 minutes after the first dose, your child may need a second dose of epinephrine. This is needed if their symptoms are worse or not getting better. Talk with your child's provider about when to use an epinephrine autoinjector and when your child needs a second dose. The provider or their staff can teach you how to use an epinephrine autoinjector.
After treatment with epinephrine, call 911 or take your child to the nearest emergency department. Your child's provider may have other directions on what to do. Always give empty epinephrine autoinjectors to the healthcare staff. Your child will need to be watched to make sure that they are not having any further reactions. This is because allergic reactions can sometimes return.
What can I do to prevent anaphylaxis in my child?
The best way to prevent anaphylaxis is to have your child stay away from known allergy triggers or allergens. Seeing an allergist can help you figure out what the trigger was. For certain allergies, there are treatments available to help prevent future allergic reactions. Talk with your child's healthcare provider about possible treatments.
How can I help my child live with anaphylaxis?
If your child has anaphylaxis, you will want to cut the risk of future episodes. You can do this by figuring out the allergen that triggered the first episode. Then you can stay away from the trigger. Your healthcare provider may also prescribe an epinephrine autoinjector. They will teach you how to use it. You can give your child a dose or shot quickly if they have an anaphylactic reaction.
