Cefepime is a bactericidal agent that acts by inhibition of bacterial wall synthesis. It has a broad spectrum of activity against a wide range of gram-positive and gram-negative bacteria including most strains resistant to aminoglycosides or third-generation cephalosporins such as ceftazidime. Cefepime is highly resistant to hydrolysis by most beta-lactamases and exhibits rapid penetration into gram-negative bacterial cells. In studies, cefepime bound with highest affinity to penicillin binding protein (PBP) 3 followed by PBP 2, then PBPs 1a and 1b.


    Forgen IV/IM 500 mg Injection: Each vial contains sterile dry mixture of Cefepime Hydrochloride USP equivalent to Cefepime 500 mg premixed with L-Arginine.
    Forgen IV/IM 1 g Injection: Each vial contains sterile dry mixture of Cefepime Hydrochloride USP equivalent to Cefepime 1 g premixed with L-Arginine.


    Cefepime is indicated for the treatment of the following infections caused by susceptible bacteria-
    ► Lower respiratory tract infections, including pneumonia and bronchitis
    ► Urinary tract infections, both complicated, including pyelonephritis, and uncomplicated infections
    ► Skin and skin structure infections
    ► Septicaemia
    ► Intra-abdominal infections, including peritonitis and biliary tract infections
    ► Empiric treatment of febrile neutropenia
    ► Surgical prophylaxis
    ► Meningitis

Dosage & Administration

    Cefepime can be administered either intravenously or intramuscularly. The dosage and route vary according to the susceptibility of the causative organisms, the severity of the infection, renal function and the overall condition of the patient.
    Guidelines for dosage of adults and aged above 12 with normal renal function-

    Infection Dose Frequency
    Severe infections including pneumonia, urinary tract infections, complicated intra-abdominal infections, including cases with an associated bacteremia 2g IV 12 hourly
    Mild to moderate urinary tract infections (uncomplicated and complicated) 500mg – 1g IV or IM
    Mild to moderate infections including bronchitis, skin and skin-structure infections 1g IV or IM
    Empiric treatment of febrile neutropenia 2g IV 8 hourly
    Surgical prophylaxis 2g IV Single dose

    * Usual duration of therapy is 7-10 days; more severe infections may require longer treatment. In the treatment of beta-haemolytic streptococcal infections a therapeutic dose must be administered for at least 10 days. For empirical treatment of febrile neutropenia, usual duration of therapy is 7 days or until resolution of neutropenia.
    Usual recommended dosages of children aged 1 month to 12 years with normal renal function-

    Infection Dose & frequency
    Pneumonia, urinary tract infections, and skin structure infections Patients 2 months of age with body weight > 40 kg: 50 mg/kg 12 hourly for 10 days. For more severe infections, a dosage schedule of 8 hourly can be used.
    Empiric treatment of febrile neutropenia Patients >2 months of age with body weight >40 kg: 50 mg/kg 8 hourly for 7-10 days.
    Experience with the use of Cefepime in paediatric patients >2 months of age is limited. A dosage of 30 mg/kg 12 hourly or 8 hourly may be considered for patients aged 1 month to 2 months.
    For paediatric patients with body weight > 40 kg, adult dosing is recommended. For patients older than 12 years who are >40 kg, the dosage recommendations for younger patients >40 kg should be used. Dosage in paediatric patients should not exceed the maximum recommended dosage in adults (2 g 8 hourly). Experience with intramuscular administration in paediatric patients is limited.

    Impaired hepatic function
    No dosage adjustment is necessary for patients with impaired hepatic function.
    Impaired renal function
    The initial dose of Cefepime is the same as in patients with normal renal function. The recommended maintenance doses of cefepime in patients with renal insufficiency are -

    Creatinine clearance Recommended Maintenance Dosage
    > 60, Usual dose, no adjustment necessary 500mg 12 hourly 1g 12 hourly 2g 12 hourly 2g 8 hourly
    30-60 500mg 24 hourly 1g 24 hourly 2g 24 hourly 1g 8 hourly
    11-19 500mg 24 hourly 500mg 24 hourly 1g 24 hourly 1g 12 hourly
    >11 250mg 24 hourly 250mg 24 hourly 500mg 24 hourly 1g 12 hourly

    Preparation of solution and administration
    Cefepime powder is to be reconstituted using the volumes of diluent shown in table-

    Single dose vial Amount of diluent to be added (ml)
    500mg IV 5
    1g IV 10
    2g IV 10
    500mg IM 1.5
    1g IM 3.0

    Cefepime is compatible at concentrations between 1 and 40 mg/ml with one of the following IV infusion fluids: (a) 0.9% Sodium Chloride Injection (b) 5% and 10% Dextrose Injection, These solutions are stable for 24 hours at room temperature or 7 days under refrigeration (2°C to 8°C).


    Cefepime is contraindicated in patients who have had previous hypersensitivity reactions to any component of the formulation, the cephalosporin class of antibiotics, penicillins or other beta-lactam antibiotics.

Warning & Precautions

    Renal function should be monitored carefully if drugs with nephrotoxic potential, such as aminoglycosides and potent diuretics, are administered with Cefepime. Pseudomembranous colitis has been reported with virtually all broad-spectrum antibiotics including Cefepime. Use of Cefepime may result in overgrowth of nonsusceptible organisms. If superinfection occur during therapy, appropriate measures should be taken.

Side effects

    Cefepime is generally well tolerated. But the most common adverse events are-
    ► Hypersensitivity - rash, pruritus, urticaria.
    ► Gastrointestinal - nausea, vomiting, oral moniliasis, diarrhea, colitis (including pseudomembranous colitis)
    ► Central nervous system - headache
    ► Other - fever, vaginitis, erythema etc.

Drug interaction

    Renal function should be carefully monitored if high doses of aminoglycosides are to be administered with cefepime or if aminoglycoside therapy is prolonged, because of the potential nephrotoxicity and ototoxicity of aminoglycoside antibiotics.

Use in special groups

    Use in pregnancy:
    Pregnancy category B. There are no adequate and well-controlled studies in pregnant women. So, this drug should be used during pregnancy only if clearly needed.
    Use in lactation:
    Cefepime is excreted in human breast milk in very low concentrations. Caution should be exercised when cefepime is administered to a nursing woman.
