Besivance is indicated for the treatment of bacterial conjunctivitis caused by susceptible strains of common gram-positive and gram-negative bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae.
Besivance is a fluoroquinolone antibiotic that works by inhibiting bacterial DNA gyrase and topoisomerase IV enzymes, which are essential for bacterial DNA replication, transcription, repair, and recombination, ultimately leading to bacterial cell death.
Besivance is for topical ophthalmic use only and should not be injected into the eye. Patients should not wear contact lenses during treatment of bacterial conjunctivitis. Common side effects may include eye redness, eye irritation, or blurred vision. As with all antibiotics, complete the full course of treatment as prescribed.
