Peanut allergy is common, especially in children. Peanut allergy symptoms can range from a minor irritation to a life-threatening reaction (anaphylaxis). For some people with peanut allergy, even tiny amounts of peanuts can cause a serious reaction.

If you or your child has had a reaction to peanuts, tell your doctor about it. Peanut allergy is one of the most common causes of severe allergy attacks. It's important to get even a minor reaction to peanuts checked out. Even if you or your child has had only a mild allergic reaction in the past, there's still a risk of a more serious future reaction.
