Ceftazidime and Avibactam Injection

The combination of ceftazidime and avibactam injection is used with metronidazole (Flagyl) to treat abdominal (stomach area) infections. It is also used to treat kidney and urinary tract infections. Ceftazidime is in a class of medications called cephalosporin antibiotics. It works by killing bacteria. Avibactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from breaking down ceftazidime. Antibiotics will not work for colds, flu, or other viral infections.

The combination of ceftazidime and avibactam injection comes as a powder to be added to fluid and injected intravenously (into a vein). It is usually infused (injected slowly) intravenously over a period of 2 hours every 8 hours. The length of your treatment depends on your general health, the type of infection you have and how well you respond to the medication. Your doctor will tell you how long to use ceftazidime and avibactam injection. You may receive ceftazidime and avibactam injection in a hospital or you may administer the medication at home.
