Ceftazidime and Avibactam Injection

pronounced as (sef taz'' i deem) and (a vi bak' tam)

Notice:

[Posted 09/22/2015]

AUDIENCE: Infectious Disease, Pharmacy

ISSUE: FDA is warning health care professionals about the risk for dosing errors with the intravenous antibacterial drug ceftazidime-avibactam (Avycaz) due to confusion about the drug strength displayed on the vial and carton labels. Ceftazidime-avibactam was initially approved with the vial and carton labels displaying the individual strengths of the two active ingredients (i.e., 2 gram/0.5 gram); however, the product is dosed based on the sum of the active ingredients (i.e., 2.5 gram). To prevent medication errors, FDA revised the labels to indicate that each vial contains ceftazidime-avibactam 2.5 gram, equivalent to ceftazidime 2 gram and avibactam 0.5 gram.

Since ceftazidime-avibactam's approval in February 2015, FDA received reports of three medication error cases related to confusion on how the strength was displayed on the ceftazidime-avibactam vial and carton labels. Two cases stated that the errors occurred during preparation of the dose in the pharmacy. The third case described concern about the potential for confusion because the strength displayed for ceftazidime-avibactam differs from how the strength is displayed for other beta-lactam/beta-lactamase drugs. Based on the information provided in the reports, FDA is aware that at least one of the patients received a higher-than-intended dose of ceftazidime-avibactam. No adverse events were reported.

BACKGROUND: Ceftazidime-avibactam is approved for intravenous administration to treat complicated infections in the urinary tract, or in combination with the antibacterial drug metronidazole to treat complicated infections in the abdomen in patients with limited or no alternative treatment options.

RECOMMENDATION: Due to reports of medication errors associated with ceftazidime-avibactam, the vial and carton labels have been revised to indicate that each vial contains ceftazidime-avibactam 2.5 gram, equivalent to ceftazidime 2 gram and avibactam 0.5 gram.

Why is this medication prescribed?

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.
