Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The data described below reflect exposure to BESIVANCE in approximately 1,000 patients between 1 and 98 years old with clinical signs and symptoms of bacterial conjunctivitis. The most frequently reported ocular adverse reaction was conjunctival redness, reported in approximately 2% of patients. Other adverse reactions reported in patients receiving BESIVANCE occurring in approximately 1-2% of patients included: blurred vision, eye pain, eye irritation, eye pruritus and headache. The most common adverse reaction reported in 2% of patients treated with BESIVANCE was conjunctival redness.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary There are no available human data for the use of BESIVANCE during pregnancy to inform any drug-associated risks; however, systemic exposure to besifloxacin from ocular administration is low [see Clinical Pharmacology (12.3) ]. Oral administration of besifloxacin to pregnant rats during organogenesis or during the prenatal and postnatal period did not produce adverse embryofetal or offspring effects at clinically relevant systemic exposures [see Data]. Data Animal Data In an embryofetal development study in rats, the administration of besifloxacin at oral doses up to 1,000 mg/kg/day during organogenesis was not associated with visceral or skeletal malformations in rat fetuses, although this dose was associated with maternal toxicity (reduced body weight gain and food consumption) and maternal mortality. Increased post-implantation loss, decreased fetal body weights, and decreased fetal ossification were also observed. At this dose, the mean C max in the rat dams was approximately 20 mcg/mL, approximately 46,500 times the mean plasma concentrations measured in humans at the recommended human ophthalmic dose (RHOD). The No Observed Adverse Effect Level (NOAEL) for this embryofetal development study was 100 mg/kg/day (C max , 5 mcg/mL, approximately 11,600 times the mean plasma concentrations measured in humans at the RHOD). In a prenatal and postnatal development study in rats, the NOAELs for both fetal/neonate and maternal toxicity were 100 mg/kg/day. At 1,000 mg/kg/day, pups weighed significantly less than controls and had a reduced neonatal survival rate. Attainment of developmental landmarks and sexual maturation was delayed, although surviving pups from this dose group that were reared to maturity did not demonstrate deficits in behavior, including activity, learning and memory, and their reproductive capacity appeared normal.
