Pregnancy & Lactation
Pregnancy
There are no available human data during pregnancy to inform any drug-associated risks; however, systemic exposure to besifloxacin from ocular administration is low; oral administration of besifloxacin to pregnant rats during organogenesis or during pre/postnatal period did not produce adverse embryofetal or offspring effects at clinically relevant systemic exposures
Lactation
There are no data on presence of drug in human milk, effects on breastfed infant, or on milk production; however, systemic exposure to besifloxacin following topical ocular administration is low, and it is not known whether measurable levels of besifloxacin would be present in maternal milk following topical ocular administration
The developmental and health benefits of breastfeeding should be considered, along with mother’s clinical need for therapy, and any potential adverse effects on breastfed infant from treatment
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

BESIFLOXACIN SUSPENSION - OPHTHALMIC
(BE-si-FLOX-a-sin)
COMMON BRAND NAME(S): Besivance
USES: This medication is used to treat bacterial eye infections. Besifloxacin belongs to a class of drugs known as quinolone antibiotics. It works by stopping the growth of bacteria.This medication treats only bacterial eye infections. It will not work for other types of eye infections (such as infections caused by viruses, fungi, mycobacteria). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
HOW TO USE: To apply eye drops, wash hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. Do not rinse the dropper. Replace the dropper cap after each use.Do not wear contact lenses while you are using this medicine or while you have the bacterial eye infection. Sterilize contact lenses according to manufacturer's directions, and check with your doctor before you begin using them again.Before use, hold the closed dropper bottle upside down and shake once to mix. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place 1 drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place a finger at the corner of your eye (near the nose) and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps if your dose is for more than 1 drop and for your other eye if so directed. This medication is used in the affected eye(s) as directed by your doctor, usually 3 times a day (with at least 4 hours or as many as 12 hours between each dose).Your dosage and length of treatment are based on your medical condition and response to treatment.If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Continue using it for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too soon may allow the bacteria to continue to grow, which may result in a return of the infection.Tell your doctor right away if your condition does not improve in a few days or if you develop new or worsening eye symptoms (such as discharge, swelling, redness, pain).
