  • The recommended duration of treatment with Fetroja is 7 to 14 days
  • The duration of therapy should be guided by the patient's clinical status
  • No dosage adjustments recommended in patients with hepatic impairment
CLcr=creatinine clearance estimated by Cockcroft-Gault equation.
Cefiderocol is removed by HD; administer cefiderocol immediately after HD for patients receiving intermittent HD.

Renal replacement dosing1

Recommended dosage of Fetroja for patients receiving continuous renal replacement therapy (CRRT)*
Effluent flow ratec 2 L/hr or less 2.1 to 3 L/hr 3.1 to 4 L/hr 4.1 L/hr or greater
Dosage of Fetroja 1.5 grams every 12 hours 2 grams every 12 hours 1.5 grams every 8 hours 2 grams every 8 hours

CVVH=continuous venovenous hemofiltration; CVVHD=continuous venovenous hemodialysis; CVVHDF=continuous venovenous hemodiafiltration.
For patients receiving CRRT, including CVVH, CVVHD, and CVVHDF, dosage of Fetroja should be based on the effluent flow rate in CRRT.
Ultrafiltrate flow rate for CVVH, dialysis flow rate for CVVHD, ultrafiltrate flow rate plus dialysis flow rate for CVVHDF.

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.

  1. 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.
  2. Allow the vial(s) to stand until the foaming generated on the surface has disappeared (typically within 2 minutes). The reconstituted solution will have a final volume of approximately 11.2 mL and concentration of 0.089 gram/mL. The reconstituted solution is for intravenous infusion only after dilution in an appropriate infusion solution.
  3. To prepare the required dose, withdraw the appropriate volume of reconstituted solution from the vial according to the table below.
  4. Add the withdrawn volume to a 100-mL infusion bag containing 0.9% sodium chloride injection, USP or 5% dextrose injection, USP.
  5. 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.

Reconstituted solutions of Fetroja

  • Upon reconstitution with appropriate diluent, immediately transfer and dilute Fetroja into the infusion bag
  • Reconstituted Fetroja can be stored for up to 1 hour at room temperature in the vial
  • Diluted Fetroja infusion solution in the infusion bag is stable for up to 6 hours at room temperature
  • Diluted Fetroja infusion solution in the infusion bag may also be refrigerated at 2°C to 8°C (36°F to 46°F) for up to 24 hours, protected from light. Then, the infusion should be completed within 6 hours at room temperature
  • Discard any unused reconstituted solution

Storage and handling

  • Store refrigerated at 2°C to 8°C (36°F to 46°F)
  • Protect from light
  • Store in carton until time of use


Fetroja solution for administration is compatible with:

  • 0.9% sodium chloride injection, USP
  • 5% dextrose injection, USP

The compatibility of Fetroja solution for administration with solutions containing other drugs or other diluents has not been established.
