Peanut allergy is common and often appears in the first years of life. While many children outgrow allergies to other foods such as milk or eggs, most kids don't outgrow peanut allergy as they get older.

An allergic reaction to peanuts can range from a minor irritation to a life-threatening reaction called anaphylaxis. Even people who have only had a mild reaction in the past are at risk of a more serious future reaction.

If your child has a peanut allergy — or you're an adult who has had a reaction — tell your doctor about it, even if it was minor. Tests can help confirm a peanut allergy, so you can take steps to avoid future and potentially worse reactions.
