Besifloxacin is a medication classified as a fluoroquinolone antibiotic. It is often prescribed to treat bacterial eye infections, such as bacterial conjunctivitis. Besifloxacin works by preventing certain proteins from being manufactured, which the bacteria need to live and reproduce. Before using this medication, patients should discuss its proper use and potential side effects with their doctors.
A patient should wash his hands before applying besifloxacin, which is only available in the form of eye drops. The bottle should be gently shaken and the patient should tilt his head back and gently pull his lower eyelid down with a finger to form a pocket. This drug should be administered into the pocket and the patient may then close his eyes gently and press his finger to the inside corner of his eye for about two minutes.
The doctor will usually prescribe one drop to one or both eyes, usually three times per day. It is important that the patient finish the full course of prescribed medication. The applicator tip of the medication bottle should not touch any surface, including the skin, to prevent the transfer of germs. Those who wear contact lenses should not do so while using this drug.
Some side effects may occur with the use of besifloxacin for eye infections, which should be reported to the prescribing physician if they become bothersome. Patients may experience temporary blurred vision or redness, pain, or itching of the treated eye. Caution should be exercised while driving if the patient's vision does become blurred.
More serious side effects may occur rarely. Patients should seek immediate medical attention if they notice new or worsening eye redness, worsening eye irritation, or severe pain. Allergic reactions to besifloxacin may also occur, and may present with a rash, hives, and itching. Swelling of the facial area, tightness in the chest, and problems breathing may also be signs of an allergic reaction. In addition, patients who use these eye drops over a long period of time may be at risk of developing a secondary infection.
Before using besifloxacin to treat an eye infection, patients must disclose their other medical conditions, as well as any supplements or medications they take, including over-the-counter medications. As of 2011, it is unknown whether the eye drops may pass into breast milk and harm a nursing infant. Women who are pregnant should discuss possible risks with their doctors. This drug is not intended for use by a child younger than 12 months old.
