Important Safety Information

Quinolones have been shown to cause arthropathy in immature animals of most species tested, the dog being particularly sensitive to this side effect. Orbifloxacin is contraindicated in dogs and cats known to be hypersensitive to quinolones. Quinolones should be used with caution in animals with known or suspected central nervous system (CNS) disorders. In such animals, quinolones have, in rare instances, been associated with CNS stimulation, which may lead to convulsive seizures. The use of fluoroquinolones in cats has been reported to adversely affect the retina and should be used with caution in cats. Blindness has also been reported post-approval in cats. In some cases, blindness has been temporary.
