Cefiderocol Injection

Cefiderocol injection is used to treat certain types of urinary tract infections in adults unable to take or receive other treatment options. It is also used to treat pneumonia in adults who are on ventilators or who were already in a hospital. Cefiderocol injection is in a class of medications called cephalosporin antibiotics. It works by killing bacteria.

Antibiotics such as cefiderocol injection will not work for colds, flu, or other viral infections. Taking or using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Cefiderocol injection comes as a powder to be added to fluid and injected intravenously (into a vein). It is usually given over a period of 3 hours every 8 hours for 7 to 14 days. The length of your treatment depends on your general health and how well you respond to the medication. You may receive cefiderocol injection in a hospital or you may administer the medication at home. If you will be receiving cefiderocol injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.

You should begin to feel better during the first few days of treatment with cefiderocol injection. If your symptoms do not improve or get worse, tell your doctor. If you still have symptoms of infection after you finish cefiderocol injection, tell your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
