Frequently asked questions
What is cefiderocol?
FETROJA is a cephalosporin antibacterial drug product consisting of cefiderocol sulfate tosylate for intravenous infusion. Cefiderocol functions as a siderophore [see Microbiology (12.4) ] .
What kind of drug is cefiderocol?
The FDA classifies cefiderocol as a cephalosporin antibacterial. Cephalosporins kill bacteria by blocking the proteins they use to build their cell walls. Without an intact wall, the bacterium cannot hold its shape and dies, which clears the infection. If you are checking whether it is safe to combine with something else, the class is what matters — two drugs from the same class usually should not be stacked.
Can you take cefiderocol with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run cefiderocol against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does cefiderocol come in?
Across the brands we track, cefiderocol is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic cefiderocol?
We do not currently list a generic-labelled cefiderocol product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
