Penicillin allergy delabeling has a significant impact on subsequent antibiotic use in primary care.

ABSTRACT: Efforts to delabel penicillin allergic patients are important as the majority of suspected penicillin allergy can be ruled out by relevant allergy testing. The aim is to change the antibiotic pattern in delabeled patients to minimize use of unnecessary broad-spectrum antibiotics, reducing the risk of antimicrobial resistance and making treatment more cost effective. However, published information on subsequent antibiotic use is scarce. To evaluate the effect of delabeling on subsequent antibiotic use in primary care, a cohort of 2911 patients tested for penicillin allergy was compared to a matched control group of 14,522 individuals from the background population. In total 86.4% of the tested patients were delabeled. For delabeled patients, penicillin use increased from 0.07 prescriptions
