  • The recommended duration of treatment with Fetroja is 7 to 14 days
  • The duration of therapy should be guided by the severity of infection and the patient's clinical status for up to 14 days
  • No dosage adjustments recommended in patients with hepatic impairment
ESRD=end-stage renal disease; HD=hemodialysis.
a CLcr=creatinine clearance estimated by Cockcroft-Gault equation.
b Cefiderocol is removed by HD; thus, complete HD at the latest possible time before the start of cefiderocol dosing.

Preparation of solution for administration1

Fetroja is a sterile, lyophilized powder that must be reconstituted and subsequently diluted using aseptic technique prior to intravenous infusion. Each single-dose, clear glass vial contains 1 gram of cefiderocol.

Reconstitute the powder for injection in the Fetroja vial with 10 mL of either 0.9% sodium chloride injection, USP or 5% dextrose injection, USP and gently shake to dissolve.
Allow the vial(s) to stand until the foaming generated on the surface has disappeared (typically within 2 minutes). The final volume of the reconstituted solution will be approximately 11.2 mL. The reconstituted solution is for intravenous infusion only after dilution in an appropriate infusion solution.
To prepare the required dose, withdraw the appropriate volume of reconstituted solution from the vial according to the table below.
Add the withdrawn volume to an infusion bag containing 100 mL of 0.9% sodium chloride injection, USP or 5% dextrose injection, USP.
Inspect drug products visually for particulate matter and discoloration prior to use—Fetroja infusions are clear, colorless solutions.

Discard any unused Fetroja solution in the vial.
