According to the American College of Allergy, Asthma, and Immunology; more than 90% of the people who think they are allergic to penicillin actually are not. A lot of people needlessly suffer and sometimes even die because they erroneously believed that they were allergic to penicillin or other antibiotics and told that to a doctor who assumed it was true. If you have been told or believe that you have an allergy to penicillin, get yourself tested by a board-certified allergist, and do it now. Don’t wait until you become sick with a serious disease that is treatable with antibiotics.
