# Self-reported beta-lactam allergy, mislabeling and inappropriate antibiotic use: a study from South India

## TL;DR

This study from South India shows that many patients labeled with beta-lactam allergies are actually at low risk, leading to unnecessary use of alternative antibiotics.

## Contribution

The study demonstrates the prevalence of mislabeled beta-lactam allergies and advocates for structured delabeling to improve antibiotic use.

## Key findings

- Over 50% of patients with a penicillin allergy label were classified as low risk.
- 21% of patients with a cephalosporin allergy label were classified as low risk.
- 44% of patients receiving alternative antibiotics due to allergy labels were found to be low-risk.

## Abstract

This study assessed beta-lactam allergy labels in 300 hospitalized adults using validated scores. Over 50% with penicillin and 21% with cephalosporin allergies were classified as low risk. Among those receiving alternative antibiotics due to inappropriate allergy labels, 44% were low-risk. Findings support structured allergy delabeling programs to enhance antimicrobial stewardship.
