Summary
Systemic polymyxin B, neomycin and bacitracin are nephrotoxic, and cidofovir causes dose-limiting proximal tubular kidney injury. Combined exposure may cause severe renal damage, and cidofovir labeling contraindicates concurrent nephrotoxic agents. Risk applies mainly to systemic or heavily absorbed use rather than small topical applications.
What this interaction means in plain words
Bacitracin-neomycin-polymyxin and Cidofovir can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Bacitracin-neomycin-polymyxin belongs to Anti Bacterial; Cidofovir belongs to Anti Virals.
Why it happens
Additive nephrotoxicity through direct renal tubular injury by both agents.
What to do
Avoid systemic or heavily absorbed use of these antibiotics during and shortly after cidofovir therapy. If unavoidable, monitor serum creatinine and urine protein closely.
