Nurse-Allergist duo takes on penicillin allergy myths
NCT ID NCT07127835
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a nurse and allergist working together can safely and effectively remove incorrect penicillin allergy labels from patients' records. About 440 people with a penicillin allergy label will be evaluated using this team approach or the standard allergist-only method. The goal is to see if the team approach is just as safe, improves quality of life, and saves money.
