Piperacillin and tazobactam injection is used to treat pneumonia and skin, gynecological, and abdominal (stomach area) infections caused by bacteria. Piperacillin is in a class of medications called penicillin antibiotics. It works by killing bacteria that cause infection. Tazobactam is in a class called beta-lactamase inhibitor. It works by preventing bacteria from destroying piperacillin.
Antibiotics such as piperacillin and tazobactam 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.
