Adult: Mild to moderate infections: 1-2 g daily in 2 divided doses. Severe infections: Up to 4 g daily in 2 divided doses. Doses are given by deep IM inj or IV infusion over at least 30 min. Child: Neonates: 30 mg/kg 12 hrly, may increase to 50 mg/kg for Pseudomonas infections; >30 days Mild to moderate infections: 100 mg/kg daily in 2 divided doses. Severe infections: Up to 150 mg/kg daily in 2 or 3 divided doses. Total dose should not exceed the recommended adult dosage.
Parenteral Empiric therapy for febrile neutropenic patients
Adult: Up to 6 g daily in 3 divided doses. Doses are given by deep IM inj or IV infusion over at least 30 min.
Special Patient Group
Critically ill patients undergoing continuous renal replacement therapy: Loading dose: 2 g. Maintenance dose: Continuous venovenous haemofiltration (CVVH): 1-2 g 12 hrly. Continuous venovenous haemodialysis (CVVHD) and haemodiafiltration (CVVHDF): 1 g 8 hrly or 2 g 12 hrly.
Abdominal infections, Urinary tract infections, Respiratory tract infection, Skin and skin structure infections: Haemodialysis: 1 g on the 1st day of treatment, followed by 0.5 g daily; dose given after haemodialysis. CAPD: Adult dose given 48 hrly.
0.25-0.5 g 24 hrly.
0.5-1 g 24 hrly.
0.5-2 g 24 hrly.
Empiric therapy for febrile neutropenic patients: Haemodialysis patients: 1 g daily. CAPD: 2 g 48 hrly.
1 g 24 hrly.
2 g 24 hrly.
2 g 12 hrly.
IV infusion: Add 5 mL, 10 mL, or 10 mL of a compatible IV soln to a vial labeled as containing 500 mg, 1 g, or 2 g, respectively, to provide soln containing approx 100 mg/mL, 100 mg/mL, or 160 mg/mL of the drug, respectively. The appropriate dose of the drug should then be added to a compatible IV soln. IM inj: Add 1.3 mL or 2.4 mL of an appropriate diluent (e.g. sterile water for inj, NaCl 0.9%) to a vial labeled as containing 500 mg or 1 g respectively, to provide a soln containing approx 280 mg/mL.
Hypersensitivity to cefepime or other cephalosporins.
Hypersensitivity to penicillins or other β-lactam antibiotics. Patient w/ history of seizure disorder, history of GI disease, particularly colitis. Renal impairment. Pregnancy and lactation. Prolonged use may result in overgrowth of non-susceptible organisms.
Monitor renal function; signs and symptoms of anaphylaxis during 1st dose.
Symptoms: Encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), myoclonus, seizures, neuromuscular excitability and non-convulsive status epilepticus. Management: Supportive treatment. Haemodialysis is recommended in case of renal insufficiency.
Increased potential for nephrotoxicity and ototoxicity of aminoglycosides. Increased risk of nephrotoxicity w/ potent diuretics (e.g. furosemide).
False positive reaction for urine glucose test using Clinitest tablets.
Description: Cefepime inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn inhibit 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 (autolysis and murein hydrolases) while cell wall assembly is arrested. Pharmacokinetics: Absorption: Rapidly and almost completely absorbed on IM inj. Time to peak plasma concentration: Approx 1.5 hr (IM); w/in 30 min (IV). Distribution: Widely distributed in body tissues and fluids; high concentrations in bile. Crosses the blood-brain barrier and enters breast milk (low concentrations). Volume of distribution: 16-20 L. Plasma protein binding: Approx 20%. Metabolism: Minimally hepatic. Excretion: Via urine (approx 85% as unchanged drug). Plasma half-life: Approx 2 hr.
