What to Do

Think Prevention!

Have kids avoid substances that are known to trigger an allergic reaction. Keep an oral antihistamine such as diphenhydramine available.

If your child has a severe allergy, be sure doctor-prescribed injectable epinephrine is kept nearby at all times, and that you, your child (if old enough), and anyone who cares for your child know how to use it.
