Background
Cefazolin is a bactericidal, time-dependent first generation cephalosporin (β-lactam) antibiotic with activity primarily against Gram-positive aerobes, and more limited activity against Gram-negative aerobes. Activity is poor against anaerobes. Cefazolin is not effective against Enterococcus spp., Pseudomonas aeruginosa, and methicillin-resistant Staphylococcus
Acceptable Uses
- Surgical prophylaxis, particularly for prolonged orthopedic procedures. Most efficacious against Gram-positive aerobic organisms. Poor choice for colorectal surgery.
- Treatment for systemic infections (e.g. sepsis) caused by susceptible organisms.
Unacceptable Uses
- N/A
