What was studied

A global systematic review and meta-analysis of case series assessed how often antibiotics are implicated in SJS/TEN, searching MEDLINE and Embase through February 22, 2022; 38 studies with 2,917 patients contributed patient-level data on single antibiotics.

Key findings

Across 38 studies (n=2,917), antibiotics were implicated in 28% of SJS/TEN cases (95% CI, 24%-33%). Among antibiotic-associated cases, sulfonamides accounted for 32% (95% CI, 22%-44%), penicillins 22% (17%-28%), cephalosporins 11% (6%-17%), fluoroquinolones 4% (1%-7%), and macrolides 2% (1%-5%); heterogeneity was statistically significant and varied by continent.

Study limitations

Substantial between-study heterogeneity was present; many reports lacked explicit drug causality assessment (sensitivity analysis with defined causality: 27% [95% CI, 17%-39%]); all included data were case series, estimating proportions among cases rather than population incidence.

Clinical implications

About one-quarter of SJS/TEN cases are antibiotic-associated worldwide, with sulfonamides leading and penicillins and cephalosporins next. When prescribing antibiotics, weigh these risks and reinforce stewardship, education, and careful duration choices.
