Increased pigmentation of iris, periorbital tissue (eyelid) & eyelashes. Potential for permanent increased brown iris pigmentation; hair growth in skin areas in contact repeatedly w/ soln. Patients w/ active intraocular inflammation (eg, uveitis); inflammatory ocular conditions eg, neovascular, inflammatory, angle-closure, congenital or narrow-angle glaucoma. Risk of developing bacterial keratitis in patients w/ disrupted ocular epithelial surface. Macular edema including cystoid macular edema. Aphakic, pseudophakic patients w/ torn posterior lens capsule, or known risk factors for macular edema (eg, intraocular surgery, retinal vein occlusions, ocular inflammatory disease & diabetic retinopathy). May decrease IOP-lowering effect w/ frequent exposure of >1 dose daily. Regularly examine patients who develop increased iris pigmentation. Inform patient of possibility of eyelash growth before treatment. Remove contact lens prior to administration & reinsert 15 min after. Monitor changes in IOP for patients in concomitant use w/ other prostaglandin analogs. May affect ability to drive & operate machine. Moderate to severe hepatic impairment. Renal impairment. Pregnancy & lactation. Not recommended in childn or adolescents/ped patients <16 yr.
