Penicillin allergy is a hypersensitivity reaction to penicillin antibiotics. While many people believe they are allergic to penicillin, true allergies are less common than often reported. Symptoms of a penicillin allergy can range from mild skin rashes and hives to severe, life-threatening reactions like anaphylaxis. Anaphylaxis is a medical emergency characterized by difficulty breathing, swelling of the throat, a sudden drop in blood pressure, and loss of consciousness.

Diagnosis of penicillin allergy is typically based on a detailed medical history and sometimes allergy testing. Allergy testing may involve skin prick tests or intradermal tests, where small amounts of penicillin are introduced to the skin to observe for a reaction. In some cases, an oral challenge under medical supervision may be performed.

If a penicillin allergy is confirmed, avoidance of penicillin and related antibiotics is crucial. These related antibiotics include other beta-lactam antibiotics like cephalosporins, though cross-reactivity varies. For individuals with a confirmed penicillin allergy, alternative antibiotics are available for treating bacterial infections.

It is important for individuals who suspect a penicillin allergy to discuss their concerns with a healthcare professional. Misdiagnosis of penicillin allergy can lead to the unnecessary avoidance of a crucial antibiotic class, potentially limiting treatment options and increasing the risk of broader-spectrum antibiotic use. In many cases, individuals diagnosed with penicillin allergy in childhood may no longer be allergic in adulthood and can be safely treated with penicillin after appropriate evaluation.
