When using Xalatan eye drops for treatment of anterior ischemic optic neuropathy, side effects are possible. Most patients do tolerate this medication well, and most who do experience side effects report that they are minor. Five to 15 percent of patients experience the most common side effects, which are blurred vision, stinging, sensation of something being stuck in the eye, eye color change, burning, red eyes, itching, and punctuate epithelial keratopathy.
The eye color change is permanent. The eyelids may also darken, but this typically goes away once the patient stops using this medication. Eyelash changes are also possible.
Other common side effects are experienced by about one to four percent of patients. These include dry eyes, eye pain, sensitivity to light, eyelid crusting, tearing of the eye, and eyelid swelling, redness, and pain.
Other possible side effects include rash, inflammation of the iris, eyelid swelling, uveitis, dizziness, chest pain, shortness of breath, headache, worsening of asthma, macular edema, eyelid inflammation, and erosions or swelling of the cornea.
