Besifloxacin is an 8-chloro fluoroquinolone anti-infective eye drop used to treat bacterial conjunctivitis, commonly known as pink eye - an infection of the membrane that covers the outer part of the eyeball and the inner parts of the eyelids. It is sold under brand name Besivance and belongs to a class of drugs called fluoroquinolones. This topical ophthalmic medication works by killing the bacteria that causes this infection. These include Pseudomonas aeruginosa, Haemophilus influenzae, Staphylococcus aureus, and Streptococcus pneumoniae. Each dose of Besivance contains 6.63 mg of besifloxacin hydrochloride equivalent to 6 mg besifloxacin base.
Besifloxacin is manufactured as a suspension (eye drops) to apply directly to the infected eye. Besivance should be applied to the affected eyes three times per day, 5-10 hours apart. The suspension should be used for seven days. It is important that you apply the medication at around the same times during the medication period. Ensure that you use Besifloxacin as directed by your healthcare provider or as indicated on the prescription label. Never use more or less of the medication, or apply it more often than prescribed by your healthcare provider.
The symptoms of eye infection should improve during the treatment period. Call your healthcare provider if the symptoms worsen or do not go away, or if you develop other complications with your eyes during treatment.
Continue using besifloxacin eye drops until you finish the prescription, even if your condition improves. If you skip doses, or stop using the medication too soon, your infection may not completely heal and the bacteria may develop resistance to antibiotics.
While administering besifloxacin, exercise caution not to let the tip of the dropper come into contact with your eye, fingers or any surface. This is meant to prevent bacteria from coming into contact with the medicine. Using medicine that is contaminated with bacteria and other pathogens may cause serious damage to your eye or even loss of vision. If you suspect your eye drops have been contaminated, get rid of it immediately and inform your healthcare provider.
To use besifloxacin eye drops, follow these steps:
Along with the intended healing effects, besifloxacin may cause some undesired side effects. Although you may not experience all these side effects, consider seeking medical attention if they become severe.
Some side effects may occur that do not require medical attention as they will go away as the body adjusts to treatment. Also, your healthcare provider may advise you on ways to manage these side effects.
Use this medication exactly as prescribed by your pharmacist or healthcare provider. Do not apply it in larger amounts or for longer than recommended. Besifloxacin should be applied three times per day for 7 days. Follow your healthcare provider's instruction and space your doses at least five hours apart.
If you miss your besifloxacin dose, apply it as soon as you remember. However, if the next dose is barely an hour away, skip the missed dose and resume your regular dosing schedule. Do not apply an extra dose to make up for the missed dose.
Besifloxacin overdose is unlikely to cause life-threatening symptoms. However, seek advice from your healthcare provider if you think you have applied too much of the drop.
Do not use besifloxacin while wearing contact lenses as the medication may contain preservatives that may be absorbed by the soft contact lenses. Wait at least 20 minutes after applying the drop before putting your contact lenses back in.
Do not wear contact lenses while you still have active symptoms of the eye infection you are treating.
It is unlikely that other medications you inject or take orally will have an effect on besifloxacin eye drops. However, most drugs tend to interact with each other. Inform your doctor about any medications you are currently on, including over-the-counter medications, mineral, supplements, drugs prescribed by other doctors, as well as herbal products. Do not start new medications without informing your healthcare provider.
