Abstract

The penicillins (amoxicillin) are among the most effective and safe antibiotics for many common bacterial respiratory infections in paediatric age and should be avoided only when a true allergy is highly suspected. Severe true antibiotic allergies are rare and allergies are often overestimated. In high-income countries, 5-15% of patients report a penicillin allergy. However, in most cases (> 95%), these patients do not have a true immunologically mediated allergy and they may very likely tolerate the antibiotic upon a new exposure. All patients defined as allergic should be carefully evaluated and their levels of antibiotic allergy risk determined. In cases of suspected penicillin allergy (e.g. those with cutaneous manifestations), skin tests are not necessary before prescribing a beta-lactam antibiotic (amoxicillin) and direct oral administration can be performed in low-risk phenotypes carefully selected according to simple protocols that do not always require a specialist evaluation. The article, based on the recommendations of the WHO Aware Manual, provides current evidence and practical guidance, and fosters a correct interpretation and management of an overestimated problem that does not promote an optimal and judicious antibiotic use.
