For uncomplicated skin abscesses, we suggest using trimethoprim-sulfamethoxazole (TMP-SMX) or clindamycin in addition to incision and drainage rather than incision and drainage alone, and emphasise the need for shared decision making
TMP-SMX or clindamycin modestly reduces pain and treatment failure and probably reduces abscess recurrence, but increases the risk of adverse effects including nausea and diarrhoea
We suggest TMP-SMX rather than clindamycin because TMP-SMX has a lower risk of diarrhoea
Cephalosporins in addition to incision and drainage are probably not more effective than incision and drainage alone in most settings
From a societal perspective, the modest benefits from adjuvant antibiotics may not outweigh the harms from increased antimicrobial resistance in the community, although this is speculative
