Patient Education

Metronidazole Injection


Metronidazole injection is used to treat certain skin, blood, bone, joint, gynecologic, and abdominal (stomach area) infections caused by bacteria. It is also used to treat endocarditis (infection of the heart lining and valves), meningitis (infection of the membranes that surround the brain and spinal cord), and certain respiratory infections, including pneumonia. Metronidazole injection is also to prevent infection when used before, during, and after colorectal surgery. Metronidazole injection is in a class of medications called antibacterials. It works by killing bacteria and protozoa that cause infection. Antibiotics such as metronidazole injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.infections of the respiratory tract, including bronchitis, pneumonia
