US antibiotic stewardship and penicillin allergy.

PURPOSE OF REVIEW: The purpose of this review is to improve otolaryngologists' antibiotic stewardship by detailing current approaches to penicillin allergy. RECENT FINDINGS: Although up to 15% of hospitalized patients in the United States have a penicillin allergy recorded on their charts, fewer than 10% of these have a true penicillin allergy. SUMMARY: Using a combination of a detailed allergy history, skin testing and graded-dose administration, many patients whose charts say 'penicillin-allergic' can safely be treated with penicillin and cross-reacting antibiotics. This permits use of narrower-spectrum antibiotics and saves money.
