Levofloxacin (levaquin), a member of the quinolone group of antibiotics, is indicated for the treatment of a wide range of bacterial infections affecting the lungs, skin and urinary tract. Levaquin works by killing bacteria or severely limiting their growth, which allows the body to properly fight an infection. The medication will not, however, work on virus infections. Levofloxacin is used treat infections such as pneumonia; chronic bronchitis; and sinus, urinary tract, kidney, and skin infections. Levofloxacin is in a class of antibiotics called fluoroquinolones.
