Does Xeroform Contain Antibiotics? Composition Clarified
Does Xeroform have antibiotics in it?
The Quick Answer
**No—Xeroform contains no antibiotics** but includes 3% **bismuth tribromophenate**, a mild antimicrobial agent that reduces bacterial load without systemic absorption or resistance development. Unlike true antibiotics (neomycin, bacitracin), bismuth disrupts bacterial adhesion through electrostatic interactions—not protein synthesis inhibition—making it suitable for colonization prevention but insufficient for active infection treatment.
Why We Ask This
Patients conflate 'antimicrobial' with 'antibiotic,' either expecting Xeroform to cure established infections (delaying necessary antibiotics) or fearing antibiotic resistance from appropriate prophylactic use—both misconceptions compromising optimal wound care decisions.
The Practical Science
Bismuth compounds prevent bacterial colonization through surface charge disruption rather than metabolic interference—mechanistically distinct from antibiotics. This non-selective action prevents resistance development but lacks bactericidal potency against established biofilms or deep tissue infections requiring systemic therapy.
In Clinical Practice
Xeroform prevents colonization in clean surgical wounds but wouldn't resolve a *Staphylococcus*-infected wound—requiring culture-directed antibiotics alongside absorptive dressings until infection clears before resuming Xeroform for the epithelialization phase of healing.
