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.
How should this medicine be used?
Piperacillin and tazobactam injection comes as a powder to be mixed with liquid and injected intravenously (into a vein). It is usually given every 6 hours, but children 9 months of age and older may receive it every 8 hours. The length of 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 piperacillin and tazobactam injection. After your condition improves, your doctor may switch you to another antibiotic that you can take by mouth to complete your treatment.
