What Is an Anaphylactic Reaction?

An extreme, life-threatening allergic reaction — usually to food, medications or insect bites -- anaphylactic reaction can result in breathing problems, dizziness, hives, a sudden drop in blood pressure, an asthma attack, or unconsciousness. It can be fatal. It must be treated promptly. An emergency kit containing epinephrine should be carried at all times by patients prone to these attacks.
