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.

Concerns related to adverse effects:
• Elevated INR: May be associated with increased INR and subsequent bleeding, especially in nutritionally deficient patients, prolonged treatment, or patients with cancer, hepatic or renal disease. Monitor coagulation parameters and manage as clinically indicated (eg, administration of phytonadione).
• Hemolytic anemia: May rarely cause hemolytic anemia (including fatalities). Has been associated with a higher risk of hemolytic anemia relative to other cephalosporins (approximately threefold); monitor carefully during use and consider cephalosporin-associated immune anemia in patients who have received cefotetan within 2 to 3 weeks (either as treatment or prophylaxis). Discontinue drug, if applicable, and institute supportive measures as clinically indicated.
• Hypersensitivity: Hypersensitivity reactions, including anaphylaxis, may occur. If an allergic reaction occurs, discontinue treatment and institute appropriate supportive measures.
• Penicillin allergy: Use with caution in patients with a history of penicillin allergy.
• 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 GI disease, particularly colitis.
• Renal impairment: Use with caution in patients with renal impairment; dosage adjustment required.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information
Monitor renal, hepatic, and hematologic function periodically with prolonged therapy. Monitor prothrombin time in patients at risk of prolongation during cephalosporin therapy (nutritionally-deficient, prolonged treatment, renal or hepatic disease). Monitor for signs and symptoms of hemolytic anemia, including hematologic parameters where appropriate.
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies. Cefotetan crosses the placenta and produces therapeutic concentrations in the amniotic fluid and cord serum. Cefotetan is one of the antibiotics recommended for use with 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 bruising, bleeding, injection site irritation, urinary retention, change in amount of urine passed, chills, pharyngitis, vaginitis, seizures, signs of hemolytic anemia (severe loss of strength and energy, dark urine, or jaundice), or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (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.
