Fluoroquinolones are a class of broad-spectrum antibiotics that are used to treat a variety of infections.

Fluoroquinolones include the following:

  • Ciprofloxacin

  • Delafloxacin

  • Gemifloxacin

  • Levofloxacin

  • Moxifloxacin

  • Norfloxacin

  • Ofloxacin

Fluoroquinolones can be taken by mouth, and some can be given intravenously or as ear or eye drops.

Fluoroquinolones work by interfering with DNA inside bacteria, resulting in death of the bacteria.
