What is moxifloxacin ophthalmic?

Moxifloxacin ophthalmic is a topical antibiotic used to treat bacterial eye infections in cats, dogs, rabbits, and other animals. 

It is used off label (extra label) in veterinary medicine. Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions carefully, as they may be significantly different from those on the label.
