The recommended adult and pediatric dosages and routes of administration are outlined in the following table. Cefepime for injection should be administered intravenously over approximately 30 minutes.

Pediatric Patients (2 months up to 16 years)
The maximum dose for pediatric patients should not exceed the recommended adult dose. The usual recommended dosage in pediatric patients up to 40 kg in weight for uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, and pneumonia is 50 mg per kg per dose, administered every 12 hours (50 mg per kg per dose, every 8 hours for febrile neutropenic patients), for durations as given above.
* including cases associated with concurrent bacteremia
** or until resolution of neutropenia. In patients whose fever resolves but who remain neutropenic for more than 7 days, the need for continued antimicrobial therapy should be re-evaluated frequently.
Patients with Hepatic Impairment
No adjustment is necessary for patients with hepatic impairment.
Patients with Renal Impairment
In patients with creatinine clearance less than or equal to 60 mL/min, the dose of cefepime for injection should be adjusted to compensate for the slower rate of renal elimination. The recommended initial dose of cefepime for injection should be the same as in patients with normal renal function except in patients undergoing hemodialysis. The recommended doses of cefepime for injection in patients with renal impairment are presented in Table 12.
When only serum creatinine is available, the following formula (Cockcroft and Gault Equation)3 may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function:
Males: Creatinine Clearance (mL/min) =
Weight (kg) x (140 – age)
72 x serum creatinine (mg/dL)
Females: 0.85 x above value

*On hemodialysis days, cefepime should be administered following hemodialysis. Whenever possible, cefepime should be administered at the same time each day.
In patients undergoing continuous ambulatory peritoneal dialysis, cefepime for injection may be administered at normally recommended doses at a dosage interval of every 48 hours (see Table 12).
In patients undergoing hemodialysis, approximately 68% of the total amount of cefepime present in the body at the start of dialysis will be removed during a 3-hour dialysis period. The dosage of cefepime for injection for hemodialysis patients is 1 g on Day 1 followed by 500 mg every 24 hours for the treatment of all infections except febrile neutropenia, which is 1 g every 24 hours.
Cefepime for injection should be administered at the same time each day and following the completion of hemodialysis on hemodialysis days (see Table 12).
Data in pediatric patients with impaired renal function are not available; however, since cefepime pharmacokinetics are similar in adults and pediatric patients (see CLINICAL PHARMACOLOGY), changes in the dosing regimen proportional to those in adults (see Tables 11 and 12) are recommended for pediatric patients.
Administration
ADD-VantageTM vials are to be constituted only with 50 mL or 100 mL of 5% Dextrose Injection or 0.9% Sodium Chloride Injection in Hospira ADD-VantageTM flexible diluent containers. (See INSTRUCTIONS FOR USE) THE RESULTING SOLUTION SHOULD BE ADMINISTERED OVER APPROXIMATELY 30 MINUTES.
Intermittent intravenous infusion with a Y-type administration set can be accomplished with compatible solutions. However, during infusion of a solution containing cefepime, it is desirable to discontinue the other solution.
Preparation of cefepime for injection solutions is summarized in Table 13.

Compatibility and Stability
Cefepime for injection in ADD-VantageTM vials is stable at concentrations of 10 to 40 mg per mL in 5% Dextrose Injection or 0.9% Sodium Chloride Injection for 24 hours at controlled room temperature 20° to 25°C or 7 days in a refrigerator 2° to 8°C.
Solutions of cefepime for injection, like those of most beta-lactam antibiotics, should not be added to solutions of ampicillin at a concentration greater than 40 mg per mL, and should not be added to metronidazole, vancomycin, gentamicin, tobramycin, netilmicin sulfate, or aminophylline because of potential interaction. However, if concurrent therapy with cefepime for injection is indicated, each of these antibiotics can be administered separately.
NOTE: PARENTERAL DRUGS SHOULD BE INSPECTED VISUALLY FOR PARTICULATE MATTER BEFORE ADMINISTRATION. IF PARTICULATE MATTER IS EVIDENT IN RECONSTITUTED FLUIDS, THE DRUG SOLUTION SHOULD BE DISCARDED.
As with other cephalosporins, the color of cefepime for injection, as well as its solutions, tend to darken depending on storage conditions; however, when stored as recommended, the product potency is not adversely affected.
INSTRUCTIONS FOR USE
These instructions for use should be made available to the individuals who perform the reconstitution steps.
To Open:
Peel overwrap at corner and remove solution container. Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually.
To Assemble Vial and Flexible Diluent Container:
(Use Aseptic Technique)
1. Remove the protective covers from the top of the vial and the vial port on the diluent container as follows:
a. To remove the breakaway vial cap, swing the pull ring over the top of the vial and pull down far enough to start the opening (SEE FIGURE 1.), then pull straight up to remove the cap. (SEE FIGURE 2.)
NOTE: Once the breakaway cap has been removed, do not access vial with syringe.
b. To remove the vial port cover, grasp the tab on the pull ring, pull up to break the three tie strings, then pull back to remove the cover. (SEE FIGURE 3.)
2. Screw the vial into the vial port until it will go no further. THE VIAL MUST BE SCREWED IN TIGHTLY TO ASSURE A SEAL. This occurs approximately 1/2 turn (180°) after the first audible click. (SEE FIGURE 4.) The clicking sound does not assure a seal; the vial must be turned as far as it will go.
NOTE: Once vial is seated, do not attempt to remove. (SEE FIGURE 4.)
3. Recheck the vial to assure that it is tight by trying to turn it further in the direction of assembly.
4. Label appropriately.
To Reconstitute the Drug:
1. Squeeze the bottom of the diluent container gently to inflate the portion of the container surrounding the end of the drug vial.
2. With the other hand, push the drug vial down into the container telescoping the walls of the container. Grasp the inner cap of the vial through the walls of the container. (SEE FIGURE 5.)
3. Pull the inner cap from the drug vial. (SEE FIGURE 6.) Verify that the rubber stopper has been pulled out, allowing the drug and diluent to mix.
4. Mix container contents thoroughly and use within the specified time.
5. Look through the bottom of the vial to verify that the stopper has been removed and complete mixing has occurred. (SEE FIGURE 7.)
If the rubber stopper is not removed from the vial and medication is not released on the first attempt, the inner cap may be manipulated back into the rubber stopper without removing the drug vial from the diluent container. Repeat steps 3 through 5.
Preparation for Administration:
(Use Aseptic Technique)
Confirm the activation and admixture of vial contents.
Check for leaks by squeezing container firmly. If leaks are found, discard unit as sterility may be impaired.
Close flow control clamp of administration set.
Remove cover from outlet port at bottom of container.
Insert piercing pin of administration set into port with a twisting motion until the pin is firmly seated. NOTE: See full directions on administration set carton.
Lift the free end of the hanger loop on the bottom of the vial, breaking the two tie strings. Bend the loop outward to lock it in the upright position, then suspend container from hanger.
Squeeze and release drip chamber to establish proper fluid level in chamber.
Open flow control clamp and clear air from set. Close clamp.
Attach set to venipuncture device. If device is not indwelling, prime and make venipuncture.
Regulate rate of administration with flow control clamp.
WARNING: Do not use flexible container in series connections.
