These symptoms can make your child feel bad, but it's not life-threatening.
Most anaphylactic reactions have symptoms in two or more areas of the body.
What Happens During Anaphylaxis?
The person's airways narrow and their throat swells, which can make it hard to breathe. Their blood vessels widen, making their blood pressure fall, sometimes to dangerous levels. A child who has had a severe allergic reaction should carry an emergency kit that includes an epinephrine auto-injector or an epi-pen. As soon as possible after the allergic reaction starts, give the child at one shot of the drug and call for an ambulance.
The injection isn’t a cure. It won’t stop a severe allergic reaction. Even if your child seems OK, emergency medical care is a must. Restock any items you use from the emergency kit so it's ready at all times.
