Medic Alert is a metal emblem that identifies its wearer as someone who has a certain medical problem. Such a problem may be a drug allergy, diabetes, heart disease, or some other condition that a doctor should know about before giving medical treatment. For example, people with severe allergies may become seriously ill or die if they take certain drugs. Such people might someday require emergency care while unconscious. If they wear a Medic Alert emblem that identifies their problem, the doctor will not give them the drugs.
