Levofloxacin eye drops are a sterile topical ophthalmic solution. Levofloxacin is a synthetic, broad-spectrum, third-generation fluoroquinolone antibiotic with bactericidal activity against a wide range of Gram-positive and Gram-negative ocular pathogens. It exerts its antibacterial effect by inhibiting bacterial topoisomerase IV and DNA gyrase, enzymes essential for DNA replication, transcription, repair, and recombination.

Levofloxacin is contraindicated in patients with known hypersensitivity to levofloxacin, other quinolones, or any component of this formulation.

Side effects have been reported in approximately 1–3% of patients. These may include transient blurred vision, fever, foreign body sensation, headache, temporary ocular burning, ocular pain or discomfort, pharyngitis, and photophobia. In less than 1% of patients, allergic reactions, eyelid edema, ocular dryness, and ocular itching have been reported.

Pregnancy Category C. Levofloxacin should be used during pregnancy only when the potential benefit justifies the potential risk to the fetus. It is not known whether levofloxacin is excreted in human milk. Therefore, caution should be exercised when levofloxacin eye drops are administered to a nursing mother.

Prolonged use may lead to the overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, treatment should be discontinued and appropriate alternative therapy should be initiated.
