Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Reconstitute vials with SWFI, bacteriostatic water for injection, NS, or D5W. For IV infusion, solutions may be further diluted in NS, D51/4NS, D51/2NS, D5NS, D5W, D10W, LR, D5LR, mannitol 5% or 10%, or sodium bicarbonate 5%.

Some products may contain sodium.
Prior to reconstitution store between 2°C and 25°C (36°F and 77°F). Avoid exposure to temperatures >50°C (122°F). Cefoxitin tends to darken depending on storage conditions; however, product potency is not adversely affected.
Reconstituted solutions of 1 g per 10 mL in sterile water for injection, bacteriostatic water for injection, sodium chloride 0.9% injection, or dextrose 5% injection are stable for 6 hours at room temperature or for 7 days under refrigeration (<5°C [43°F]).
DUPLEX container: Store unactivated container at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F); do not freeze. Following activation, solution is stable for 12 hours at room temperature and 7 days refrigerated.
Aminoglycosides: Cephalosporins (2nd Generation) may enhance the nephrotoxic effect of Aminoglycosides. Monitor therapy
BCG (Intravesical): Antibiotics may diminish the therapeutic effect of BCG (Intravesical). Avoid combination
BCG Vaccine (Immunization): Antibiotics may diminish the therapeutic effect of BCG Vaccine (Immunization). Monitor therapy
Cholera Vaccine: Antibiotics may diminish the therapeutic effect of Cholera Vaccine. Management: Avoid cholera vaccine in patients receiving systemic antibiotics, and within 14 days following the use of oral or parenteral antibiotics. Avoid combination
Lactobacillus and Estriol: Antibiotics may diminish the therapeutic effect of Lactobacillus and Estriol. Monitor therapy
Probenecid: May increase the serum concentration of Cephalosporins. Monitor therapy
Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Consider therapy modification
Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine. Only the live attenuated Ty21a strain is affected. Management: Vaccination with live attenuated typhoid vaccine (Ty21a) should be avoided in patients being treated with systemic antibacterial agents. Use of this vaccine should be postponed until at least 3 days after cessation of antibacterial agents. Consider therapy modification
Vitamin K Antagonists (eg, warfarin): Cephalosporins may enhance the anticoagulant effect of Vitamin K Antagonists. Monitor therapy
Positive direct Coombs', false-positive urinary glucose test using cupric sulfate (Benedict's solution, Clinitest®, Fehling's solution), false-positive serum or urine creatinine with Jaffé reaction
1% to 10%: Gastrointestinal: Diarrhea
<1%: Anaphylaxis, angioedema, bone marrow depression, dyspnea, eosinophilia, exacerbation of myasthenia gravis, exfoliative dermatitis, fever, hemolytic anemia, hypotension, increased blood urea nitrogen, increased serum creatinine, increased serum transaminases, interstitial nephritis, jaundice, leukopenia, nausea, nephrotoxicity (increased; with aminoglycosides), phlebitis, prolonged prothrombin time, pruritus, pseudomembranous colitis, skin rash, thrombocytopenia, thrombophlebitis, toxic epidermal necrolysis, urticaria, vomiting
Concerns related to adverse effects:
• Hypersensitivity: Use with caution in patients with a history of penicillin allergy, especially IgE-mediated hypersensitivity reactions (eg, anaphylaxis, angioedema, urticaria). If a hypersensitivity reaction occurs, discontinue immediately.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• GI disease: Use with caution in patients with a history of gastrointestinal disease, particularly colitis.
• Renal impairment: Use with caution in patients with renal impairment; modify dosage in severe impairment.
• Seizure disorders: Use with caution in patients with a history of seizure disorder; high levels, particularly in the presence of renal impairment, may increase risk of seizures.
• Children: In pediatric patients ≥3 months of age, higher doses have been associated with an increased incidence of eosinophilia and elevated AST.
• Elderly: This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Elderly patients are more likely to have decreased renal function; use care in dose selection and monitor renal function.
• Discontinuation of therapy: For group A beta-hemolytic streptococcal infections, antimicrobial therapy should be given for at least 10 days to guard against the risk of rheumatic fever or glomerulonephritis.
Monitor renal function periodically when used in combination with other nephrotoxic drugs; prothrombin time. Observe for signs and symptoms of anaphylaxis during first dose.
Adverse events have not been observed in animal reproduction studies. Cefoxitin crosses the placenta and reaches the cord serum and amniotic fluid.
Peak serum concentrations of cefoxitin during pregnancy may be similar to or decreased compared to nonpregnant values. Maternal half-life may be shorter at term. Pregnancy-induced hypertension increases trough concentrations in the immediate postpartum period. Cefoxitin is one of the antibiotics recommended for prophylactic use prior to cesarean delivery.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of myasthenia gravis (muscle weakness, difficulty chewing, difficulty swallowing, difficulty breathing, droopy eyelids, vision changes, blurred vision, or double vision), bruising, bleeding, severe loss of strength and energy, chills, pharyngitis, seizures, injection site irritation, flushing, shortness of breath, severe dizziness, passing out, dark urine, jaundice, or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (rare) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
