Postmarketing Reports
Neurotoxicity: Encephalopathy, aphasia, nonconvulsive status epilepticus
Other: Anaphylaxis (including anaphylactic shock), transient leukopenia
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
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
Clostridium difficile-associated diarrhea (CDAD) may occur and should be considered in all patients who present with persistent diarrhea after use
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 has been reported, including life-threatening or fatal occurrences such as aphasia, encephalopathy, myoclonus, seizures, and nonconvulsive status epilepticus
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 category: B
Lactation: Drug enters breast milk; use with caution
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)
