Noroxin is use to treat a wide variety of bacterial infections. These types of infections are caused by bacteria and can be located in the upper respiratory, ear, skin, urinary tract, and bones; there are many other places in the body a bacterial infection can occur. Examples of these infections include pneumonia, tuberculosis, gastritis, and food poisoning. Most bacterial infections cause fevers and discomfort and can be relieved with an antibiotic!

Noroxin is effective in treating bacterial infections because of its ability to stop the growth of the bacteria so the immune system can defend against it more easily.
