Feedback:
The actions of polymyxin B on cell membranes means it can be toxic to the human host, leading to nephrotoxicity, neurotoxicity (e.g., facial flushing, dizziness, ataxia, paresthesias, drowsiness), and drug-related fever and rash. This drug is reserved for infections that do not respond to less toxic drugs; the nurse needs to be alert for serious reactions and hold the drug until notifying the provider.
