Xalatan (latanoprost) — Uses, Dosage, Side Effects & Safety

Drug class: Prostaglandin analog (antiglaucoma agent)

Overview

Xalatan is an eye drop medication used to lower high pressure inside the eye, most commonly in people with open-angle glaucoma or ocular hypertension. By reducing intraocular pressure (IOP), Xalatan helps prevent damage to the optic nerve and loss of vision. Xalatan contains latanoprost, a prostaglandin analog. It works by increasing the natural outflow of fluid (aqueous humor) from the eye, which helps lower eye pressure. Patients should use Xalatan exactly as prescribed, usually once daily in the evening. Consistent use is important for protecting vision, even if you do not notice any symptoms. Key points: Xalatan does not cure glaucoma but helps control it. Do not stop using the drops without consulting your doctor. Inform your healthcare provider about any eye changes, allergies, or if you are pregnant or breastfeeding.
