Linezolid injection is used to treat infections, including pneumonia, and infections of the skin. Linezolid is in a class of anti-bacterial called oxazolidinones. It works by stopping the growth of bacteria.
Antibiotics such as linezolid injection will not kill viruses that can cause colds, flu, or other infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
