JT is a 58-year-old women who is on vancomycin empirically for pyomyositis confirmed by MRI. Surgical debridement has successfully removed infected tissue and pus. C&S of the infected tissue comes back MSSA sensitive to everything on the panel. JT is allergic to PCN (rash), she has had cephalosporin for her UTI in the past with no problem.
What would be the most appropriate antibiotics to switch to while JT is still in the hospital?
Correct Answer: E
Cefazolin or an antistaphylococcal penicillin (oxacillin or nafcillin) is recommended for this patient because the C&S results indicate MSSA. Since the patient develops a rash to penicillins, it would be acceptable to use cefazolin in this case.
