Diarrhea (1%)
Hepatic enzyme elevation (1%)
Hypersensitivity reaction (1%)
<1%
Prolongation of bleeding time
Neutropenia
Thrombocytopenia
Immune-mediated hemolytic anemia
Warnings
Contraindications
Hypersensitivity to drug or excipients
Previously experienced cephalosporin-associated hemolytic anemia
Cautions
Reduce dosage by 1/2 if <10-30 mL/min creatinine clearance and by 1/4 if <10 mL/min; (high doses may cause CNS toxicity); bacterial or fungal overgrowth of nonsusceptible organisms may occur with prolonged or repeated therapy
Inappropriate for pediatric mild-moderate infections (AAP)
Before initiating therapy, make careful inquiry to determine whether patient has had previous cross-hypersensitivity reaction to beta-lactams; if allergic reaction to this drug occurs, discontinue drug; serious hypersensitivity reactions may require treatment with epinephrine and other emergency measures, including oxygen, intravenous fluids, antihistamines corticosteroids, pressor amines, and airway management
In common with many other broad-spectrum antibiotics, this drug may be associated with a fall in prothrombin activity and, possibly, subsequent bleeding; those at increased risk include patients with renal or hepatobiliary impairment or poor nutritional state, the elderly, and patients with cancer; prothrombin time should be monitored and exogenous vitamin K administered as indicated
Prescribing this antibiotic in the absence of proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria
As with other broad-spectrum antibiotics, prolonged use may result in overgrowth of nonsusceptible organisms; careful observation of the patient is essential; if superinfection occurs during therapy, appropriate measures should be taken
This antibiotic should be used with caution in individuals with a history of gastrointestinal disease, particularly colitis
Immune hemolytic anemia
- Immune hemolytic anemia has been reported in patients receiving cephalosporins; severe cases of hemolytic anemia, including fatalities, reported in association with the administration of this drug; reports are uncommon
- Consider diagnosis of cephalosporin-associated anemia and stop therapy until etiology determined with certainty if patient develops anemia anytime within 2-3 weeks subsequent to administration of this drug; may consider blood transfusion as needed
- Patients receiving courses of this drug for treatment or prophylaxis of infections should have periodic monitoring for signs and symptoms of hemolytic anemia, including measurement of hematological parameters where appropriate
Clostridium difficile-associated diarrhea
- Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis
- Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile; C. difficile produces toxins A and B which contribute to development of CDAD; hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy
- CDAD must be considered in all patients who present with diarrhea following antibiotic use; careful medical history is necessary since CDAD has been reported to occur over two months after administration of antibacterial agents
- If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued; appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated
Pregnancy & Lactation
Pregnancy
Available data from published observational studies and case reports over several decades with drug use in pregnant women have not established a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes
Animal data
- In animal reproduction studies, no adverse developmental effects were observed when pregnant rats and monkeys were treated, during period of organogenesis, at doses up to approximately 3 and 2 times maximum recommended human dose (MRHD), respectively
- Maternal gonorrhea may be associated with preterm birth, low neonatal birth weight, chorioamnionitis, intrauterine growth restriction, small for gestational age and premature rupture of membranes; perinatal transmission of gonorrhea to offspring can result in infant blindness, joint infections and bloodstream infections
Lactation
Published literature reports that drug is present in human milk at low levels following intravenous administration; there is no information regarding effects of cefotetan on milk production or the breastfed infant; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Second-generation cephalosporin used as single-drug therapy to provide broad gram-negative coverage and anaerobic coverage. Also provides some coverage of gram-positive bacteria. Half-life is 3.5 h. Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins; inhibits final transpeptidation step of peptidoglycan synthesis, resulting in cell wall death
Pharmacokinetics
Half-Life: 2.8-4.6 hr
Peak Plasma Time: 1.5-3 hr (IM)
Protein Bound: 76-90%
Distribution: Body fluids & tissue, including bile, sputum, prostatic & peritoneal fluids, low in CSF
Metabolism: Liver
Excretion: urine primarily unchanged; feces (20%)
