This meta-analysis of 4 RCTs found anti-MRSA antibiotics in addition to I&D led to a far better cure rate than I&D alone.
Why does this matter?
In the past, the literature has gone back and forth about whether or not antibiotics are helpful for abscesses. Is I&D enough? However, more recent studies have shown that both small and large abscesses appear to benefit from giving antibiotics. This meta-analysis pooled several studies to get a consensus.
Yup, give antibiotics
This was a systematic review and meta-analysis of 4 RCTs, mostly using TMP/SMX, with 2406 patients and found the treatment failure rate was 7.7% with antibiotics, 16.1% without. Adverse effects from antibiotics were largely minor (rash, GI upset) and not much worse than placebo, 24.8% with antibiotics, 22.1% without. Fewer patients developed new lesions when given antibiotics. The consensus is in – give anti-MRSA antibiotics for abscesses in addition to I&D.
