What is ofloxacin?
Ofloxacin is in a group of antibiotics called fluoroquinolones (flor-o-KWIN-o-lones). Ofloxacin

gonorrhea, skin infections, urinary tract infections, and infections of the prostate.
Ofloxacin may also be used for other purposes not listed in this medication guide.

such as ciprofloxacin (Cipro), levofloxacin (Levaquin), moxifloxacin (Avelox), norfloxacin (Noroxin),
lomefloxacin (Maxaquin), and others.
Before taking ofloxacin, tell your doctor if you have a heart rhythm disorder, especially if you
