Cefepime is given as hydrochloride by deep intramuscular injection, or intravenously by infusion over at least 30 minutes. Doses are expressed in terms of the equivalent amount of cefepime. 1.19 g of Cefepime hydrochloride is approximately equivalent to 1 gram of Cefepime. The usual adult dose is 1 to 2 grams daily in 2 divided doses for mild to moderate injections, increased to 4 g daily in 2 divided doses in severe infections, although up to 6 g daily in 3 divided doses has been given for febrile neutropenia. Children aged over 2 months and weighing up to 40 kg may be given 50 mg/kg twice daily; this dose may be given 3 times daily for febrile neutropenia.
Administration in Renal Impairment: Dosage of cefepime should be modified in renal impairment; after a normal initial loading dose the maintenance dosage should be adjusted according to the patient's creatinine clearance (CC) and the severity of the infection: CC 30 to 60 mL/minute: 0.5 to 2 g every 24 hours.
CC 11 to 29 mL/minute: 0.5 to 1 g every 24 hours.
CC 10 mL/minute or less: 250 to 500 mg every 24 hours.
Patients undergoing haemodialysis should be given a repeat dose (equivalent to the initial dose) after each dialysis session, while those undergoing continuous ambulatory peritoneal dialysis should receive normal recommended doses at intervals of 48 hours.
