Dialysis Notes

There are other more effective, less toxic alternatives for most multidrug-resistant Gram-negative infections.  If a polymyxin is required, polymyxin B is preferred for intravenous treatment of systemic infections in adults. For treatment of urinary tract infections, or use via inhalation, use colistin (polymyxin E).
