5 WARNINGS AND PRECAUTIONS Hypersensitivity ( 5.1 ) Growth of Resistant Organisms with Prolonged Use ( 5.2 ) Corneal Endothelial Cell Injury ( 5.3 ) 5.1 Hypersensitivity Some patients receiving topical ophthalmic gatifloxacin experienced hypersensitivity reactions including anaphylactic reactions, angioedema (including pharyngeal, laryngeal, or facial edema), dyspnea, urticaria, and itching, even following a single dose. Rare cases of Stevens-Johnson Syndrome were reported in association with topical ophthalmic gatifloxacin use. If an allergic reaction to gatifloxacin occurs, discontinue the drug [see Patient Counseling Information ( 17 )]. 5. 2 Growth of Resistant Organisms with Prolonged Use Prolonged use of gatifloxacin ophthalmic solution 0.5% may result in overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. Whenever clinical judgment dictates, examine the patient with the aid of magnification, such as slit lamp biomicroscopy and where appropriate, fluorescein staining. 5. 3 Corneal Endothelial Cell Injury Gatifloxacin ophthalmic solution 0.5% is for topical ophthalmic use. Gatifloxacin ophthalmic solution 0.5% may cause corneal endothelial cell injury if introduced directly into the anterior chamber of the eye.

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hypersensitivity [ see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 ) ] Growth of Resistant Organisms With Prolonged Use [ see Warnings and Precautions ( 5.2 ) ] Corneal Endothelial Cell Injury [ see Warnings and Precautions ( 5.3 ) ] Most common adverse reactions occurring in ≥ 1% of patients included worsening of conjunctivitis, eye irritation, dysgeusia, and eye pain.

In clinical studies of patients with bacterial conjunctivitis treated with gatifloxacin ophthalmic solution 0.5% (N=717), the most frequently reported adverse reactions occurring in ≥ 1% of patients were: worsening of the conjunctivitis, eye irritation, dysgeusia, and eye pain. Additional adverse reactions reported with other formulations of gatifloxacin ophthalmic solution in other clinical studies included chemosis, conjunctival hemorrhage, dry eye, eye discharge, eyelid edema, headache, increased lacrimation, keratitis, red eye, papillary conjunctivitis, and reduced visual acuity. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of gatifloxacin ophthalmic solution 0.5% or with other formulations of gatifloxacin ophthalmic solution. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions included anaphylactic reactions and angioedema (including pharyngeal, oral or facial edema), blepharitis, dyspnea, eye pruritus, eye swelling (including corneal and conjunctival edema), hypersensitivity, including signs and symptoms of eye allergy and allergic dermatitis, nausea, pruritus (including pruritus generalized, rash, urticaria), and vision blurred.
