What is Besifloxacin?

Besifloxacin is an ophthalmic antibiotic designed to treat bacterial conjunctivitis, commonly known as pink eye. Its potent antimicrobial activity covers a wide range of grampositive and gramnegative bacteria, making it effective against common pathogens causing eye infections. Besifloxacin is specifically formulated as eye drops for localized treatment.

Uses of Besifloxacin

• Bacterial Conjunctivitis: Treats pink eye caused by susceptible bacteria, reducing infection and associated symptoms like redness, itching, and discharge.
• PostSurgical Infection Prevention (OffLabel): Occasionally used prophylactically in patients undergoing eye surgery to prevent bacterial infections.

Dosage of Besifloxacin

For Bacterial Conjunctivitis:

Adults and Children (1 Year and Older): Instill 1 drop into the affected eye(s) three times daily (approximately every 4-12 hours) for 7 days.

Administration Instructions:

• Wash hands thoroughly before use.
• Shake the bottle well before each application.
• Tilt your head back and pull down your lower eyelid to create a small pocket.
• Instill one drop into the pocket without touching the dropper tip to your eye or skin.
• Close your eyes for a few seconds to allow the medication to spread evenly.

Important: Do not wear contact lenses while using Besifloxacin, as it may worsen irritation or trap bacteria.
