Noroxin is prescribed to treat a variety of bacterial infections. Noroxin
belongs to a class of drugs called quinolone antibiotics. It works by stopping
the growth of bacteria. This antibiotic only treats bacterial infections. It
will not work for viral infections (common cold, flu). Unnecessary use
or overuse of any antibiotic can lead to its decreased effectiveness.
Noroxin is an antibacterial medication prescribed to treat infections of the urinary tract, including cystitis (inflammation of the inner lining of the bladder caused by a bacterial infection), prostatitis (inflammation of the prostate gland), and certain sexually transmitted diseases, such as gonorrhea.
