 | Penicillin allergy is the most commonly reported medication allergy, with more than 10% of hospitalized patients reporting an allergy to penicillin. However, approximately 90% of people reporting a penicillin allergy aren't actually allergic to the medication. Many people reporting a penicillin allergy either were never allergic, or may have had an allergy in the past, but have lost that allergy over time. The problem with people reporting a penicillin allergy is that more expensive, broad-spectrum antibiotics are used instead, which can cause problems such as antibiotic-resistant bacteria and superinfections such as Clostridium difficile. Penicillin skin testing is available as a way to determine if a person is actually allergic to penicillin. This is a simple procedure that most allergists perform in their offices, and takes less than a few hours to perform. If penicillin allergy testing shows no evidence of penicillin allergy, a person should be able to take penicillin safely in the future, which is a less expensive antibiotic often with fewer side effects. | |

| All About Penicillin Allergy
Penicillin is perhaps the most well-known member of a group of antibiotics called beta lactams, which refers to a particular structure in their chemical makeup. The structure is also shared by semi-synthetic penicillin (amoxicillin), cephalosporins, and other antibiotics (such as imipenem). Penicillins and cephalosporins are the most commonly used antibiotics to treat common infections. Penicillins and cephalosporins are also the most common causes of drug allergy. About 10% of Americans report an allergy to penicillin or a related antibiotic. While penicillin allergy most commonly occurs in young adults, reactions can occur at any age. Women appear to be at higher risk than men. Approximately 300 deaths can be attributed to penicillin allergy each year in the United States. Symptoms of an allergic reaction to penicillin may include anaphylaxis, hives, below-the-skin swelling, asthma symptoms, as well as non-allergic symptoms such as serum sickness, certain forms of anemia, and other drug rashes.
