Tigecycline Overview

  • Tigecycline injection used to treat certain serious infections including community acquired pneumonia (a lung infection that developed in a person who was not in the hospital), skin infections, and infections of the abdomen (area between the chest and the waist). Tigecycline injection should not be used to treat pneumonia that developed in people who are on ventilators or who were in a hospital or foot infections in people who have diabetes. Tigecycline injection is in a class of medications called tetracycline antibiotics. It works by killing bacteria that cause infection.

  • Antibiotics such as tigecycline injection will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
