In Phase III clinical trials, the adverse-event profile of ZAVICEFTA was similar to that seen with either best available therapy, doripenem or meropenem.2–4

It is recommended that Zavicefta should be used to treat infections due to aerobic Gram-negative organisms in adult patients with limited treatment options only after consultation with a physician with appropriate experience in the management of infectious diseases.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.
