Abstract

The negative consequences of having a penicillin allergy label are well established. Penicillin allergy de-labelling improves healthcare outcomes; however, less attention is paid to modifying risk factors leading to penicillin allergy development. In this propensity score-matched retrospective cohort study, we used a de-identified population-based database (TriNetX Research Network) and examined the 30-day risk of acquiring a penicillin allergy label in patients using proton pump inhibitors (PPIs). We demonstrated a higher risk of acquiring a penicillin allergy label among PPI users compared to controls.
