Treatment of infections caused by susceptible bacteria, including intra-abdominal infections, gynecological infections, septicemia, bone and joint infections, and lower respiratory tract infections. Also used for surgical prophylaxis.

Cefoxitin works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) and disrupts the peptidoglycan layer of the bacterial cell wall, leading to cell death. It is resistant to many beta-lactamases, giving it a broader spectrum than first-generation agents.

Administered intravenously or intramuscularly. May cause allergic reactions in patients with penicillin or cephalosporin hypersensitivity. Common side effects include local injection site reactions, diarrhea, and rash. Use with caution in patients with impaired renal function.
