Patient Education

Imipenem, Cilastatin, and Relebactam Injection


Imipenem, cilastatin, and relebactam injection is used to treat adults with certain serious urinary tract infections including kidney infections, and certain serious abdominal (stomach) infections when there are few or no other treatment options. It is also used to treat certain types of pneumonia that developed in adults who are on ventilators or who were already in a hospital. Imipenem is in a class of medications called carbapenem antibiotics. It works by killing bacteria. Cilastatin is in a class of medications called dehydropeptidase inhibitors. It works by helping imipenem stay active in your body for a longer period of time. Relebactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying imipenem. Antibiotics such as imipenem, cilastatin, and relebactam 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.
