Penicillin sensitivity might not be your reality; a pharmacist clarifies why this could be the case and offers insights on confirming your status for sure
In the world of antibiotics, Penicillin remains a staple, targeting specific types of bacteria to treat common infections. First discovered in 1928, it became widely used in the 1940s, and today, Penicillin and closely related antibiotics such as amoxicillin and amoxicillin/clavulanate are frequently prescribed.
However, misconceptions about Penicillin allergies are common. Contrary to popular belief, a mild, self-limiting rash is not indicative of a Penicillin allergy. But severe facial swelling and trouble breathing can be symptoms of a true allergy.
Elizabeth W. Covington, Associate Clinical Professor of Pharmacy at Auburn University, specializes in studying antibiotics and drug allergies. She emphasizes the importance of accurate Penicillin allergy determination, as incorrect labels can put individuals at an increased risk of antimicrobial resistance.
In many cases, an interview with a health care professional is enough to determine that a person isn't allergic to Penicillin. A health care professional may ask several questions to distinguish between a true allergy and a nonallergic reaction. If the interview doesn't provide enough information, further testing may be recommended.
One such method is Penicillin skin testing. This safe and reliable method can help confirm a true Penicillin allergy. In some cases, skipping the skin test and going straight to a small test dose can also be a safe way to check for a true allergy, as a study published in 2023 has shown.
A small dose of amoxicillin while being monitored at a doctor's office can be used to confirm it's safe after skin testing. It's crucial to note that people who report having a Penicillin allergy are more likely to receive broad-spectrum antibiotics, which kill many types of bacteria, including helpful ones, making it easier for resistant bacteria to survive and spread.
In light of these facts, it's essential to approach Penicillin allergy claims with caution. Misconceptions can lead to inappropriate and potentially harmful treatments. For accurate and safe management of Penicillin allergies, always consult with a healthcare professional.
