Warnings
Contraindications
Documented hypersensitivity to cefepime, penicillins, or other beta-lactam antibiotics
Cautions
IM recommended only for mild-to-moderate complicated or uncomplicated UTI due to E coli
Prescribing drug in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to patient and increases risk of development of drug-resistant bacteria
Prolonged use may cause superinfection
May increase international normalized ratio (INR) with prolonged treatment, especially in nutritionally deficient patients
Caution warranted with history of previous immediate hypersensitivity reactions to cefepime, cephalosporins, penicillins, or other drugs; exercise caution if product is to be given to penicillin-sensitive patients; cross-hypersensitivity among beta-lactam antibacterials documented to occur up to 10% of patients with history of penicillin allergy; if allergic reaction to this drug occurs, discontinue drug and institute appropriate supportive measures
Use with caution in patients with GI disease, particularly colitis
If CrCl <60 mL/min, adjust dosage to compensate for slower renal elimination rate
Neurotoxicity
- Neurotoxicity has been reported, including life-threatening or fatal occurrences such as aphasia, encephalopathy, myoclonus, seizures, and nonconvulsive status epilepticus
- Most cases occurred in patients with renal impairment who did not receive appropriate dosage adjustment; however, some cases of neurotoxicity occurred in patients receiving a dosage adjustment appropriate for their degree of renal impairment
- In majority of cases, symptoms of neurotoxicity were reversible and resolved after discontinuation of therapy and/or after hemodialysis; if neurotoxicity associated with cefepime therapy occurs, discontinue therapy and institute appropriate supportive measures
Clostridioides difficile
- Clostridioides difficile-associated diarrhea (CDAD) may occur and should be considered in all patients who present with persistent diarrhea after use
- Careful medical history is necessary since CDAD has been reported to occur over two months after administration of antibacterial agents
- 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
- 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 antibacterial drug use not directed against C. difficile may need to be discontinued
- Appropriate fluid and electrolyte management, protein supplementation, antibacterial drug treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated
Nonconvulsive status epilepticus
- Risk of nonconvulsive status epilepticus may be increased if inadequate dosing adjustment is made with renal impairment
- Most cases occurred in patients with renal impairment who did not receive appropriate dosage adjustment; however, some occurred in patients receiving dosage adjustment appropriate for their degree of renal impairment
- Signs and symptoms of nonconvulsive status epilepticus may include altered mental status, confusion, and decreased responsiveness
Pregnancy & Lactation
Pregnancy
There are no cases of drug exposure during pregnancy reported from postmarketing experience or from clinical trials; available data from published observational studies and case reports over several decades with cephalosporin use in pregnant women have not established drug-associated risks of major birth defects, miscarriage or adverse maternal or fetal outcomes
Animal data
- Cefepime was not associated with adverse developmental outcomes in rats, mice, or rabbits when administered parenterally during period of organogenesis; the doses used in these studies were 1.6 times (rats), approximately equal to (mice) and 0.3 times (rabbits) the maximum recommended clinical dose
Lactation
Drug is present in human milk at low concentration (0.5 mcg/mL); a nursing infant consuming approximately 1000 mL of human milk per day would receive approximately 0.5 mg of cefepime per day
There is no information regarding effects on milk production or on breastfed infant
Developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for cefepime 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
Fourth-generation cephalosporin; has gram-negative coverage comparable to ceftazidime but better gram-positive coverage (comparable to ceftriaxone); is zwitterion and rapidly penetrates gram-negative cells; is best beta-lactam for IM administration; has poor capacity to cross blood-brain barrier and thus is not used for treatment of meningitis
Absorption
IM absorption rapid and complete
Peak plasma time: 0.5-1.5 hr (IV); 1-2 hr (IM)
Distribution
Penetrates into inflammatory fluid at concentrations ~80% of serum levels and into bronchial mucosa at concentrations ~60% of plasma levels; crosses blood-brain barrier
Protein bound: 16-19%
Vd: 16-20 L (adults)
Metabolism
Minimally metabolized in liver
Elimination
Half-life: 2 hr
Excretion: Urine (85% as unchanged drug)
