4: Is it safe to administer cefazolin in penicillin-allergic patients?

We investigate the claim that an alternative antibiotic to cephalosporins (e.g., cefazolin) should be selected for penicillin-allergic patients in the perioperative setting.  Claim 1. Alternative antibiotics may be as efficacious in preventing surgical site infections Claim 2. Cephalosporins (e.g., cefazolin) may be unsafe due to cross-reactivity.  Claim 3. Administering cephalosporins (e.g., cefazolin) may be against the standard of care.
