Allergic Reaction
An allergic reaction is the body's way of responding to an "invader." When the body senses a foreign substance, called an antigen, the immune system is triggered. The immune system normally protects the body from harmful agents such as bacteria and toxins. Its overreaction to a harmless substance (an allergen) is called a hypersensitivity reaction, or an allergic, reaction. Anything can be an allergen. Common dust, pollen, plants, medications, certain foods, insect venoms, animal dander, viruses, or bacteria are examples of allergens. Reactions may occur in one spot, such as a small skin rash or itchy eyes, or all over, as in a whole body rash. A reaction may include one or several symptoms. In rare cases, an allergic reaction can be life-threatening (known as anaphylaxis). Each year in the United States, over 400 people die from anaphylactic reactions to penicillin, and nearly 100 Americans die from anaphylactic reactions to insects, according to the Asthma and Allergy Foundation of America (AAFA).
