Xalatan is used to treat open-angle glaucoma and ocular hypertension (elevated pressure inside the eye). It helps reduce the risk of vision loss by lowering intraocular pressure when other treatments are insufficient or not tolerated.
Xalatan contains latanoprost, a prostaglandin F2α analog. It works by increasing the outflow of aqueous humor through the uveoscleral pathway, which reduces pressure inside the eye.
Xalatan is for ophthalmic use only and should be applied as a single drop in the affected eye(s) once daily in the evening. Common side effects may include eye redness, eyelash changes, and iris pigmentation changes. Patients should remove contact lenses before use and wait 15 minutes before reinserting. Always follow your healthcare provider's specific dosing instructions.
