Besifloxacin ophthalmic is used to treat bacterial conjunctivitis (pinkeye; infection of the membrane that covers the outside of the eyeballs and the inside of the eyelids). Besifloxacin is in a class of medications called fluoroquinolones. It works by killing the bacteria that cause infection.
Besifloxacin comes as an ophthalmic suspension (eye drops) to apply to the eyes. It is usually applied to the affected eye(s) three times a day, 4 to 12 hours apart, for 7 days. Use besifloxacin eye drops at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use besifloxacin eye drops exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
You should expect your symptoms to improve during your treatment. Call your doctor if your symptoms do not go away or get worse, or if you develop other problems with your eyes during your treatment.
Use besifloxacin eye drops until you finish the prescription, even if you feel better. If you stop using besifloxacin eye drops too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
When you use besifloxacin eye drops, be careful not to let the tip of the bottle touch your eye, fingers, or any surface. If the tip does touch another surface, bacteria may get into the eye drops. Using eye drops that are contaminated with bacteria may cause serious damage to the eye or loss of vision. If you think your eye drops have become contaminated, call your doctor or pharmacist.
Wash your hands thoroughly with soap and water.
Check the dropper tip to make sure that it is not chipped or cracked.
Avoid touching the dropper tip against your eye or anything else; eyedrops and dropper must be kept clean.
While tilting your head back, pull down the lower lid of your eye with your index finger to form a pocket.
Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
Brace the remaining fingers of that hand against your face.
While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
Place a finger on the tear duct and apply gentle pressure.
Wipe any excess liquid from your face with a tissue.
If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
Replace and tighten the cap on the dropper bottle. Do not wipe or rinse the dropper tip.
Wash your hands to remove any medication.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Place the missed dose in your eye(s) as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not use a double dose to make up for a missed one.
