Xalatan is an eye drop used for lowering eye pressure in people with high eye pressure or open angle glaucoma. It belongs to a class of medications called prostaglandins and works by opening the channels that drain fluid from the eye. The medication, which is available by prescription, is generally used once daily in the evening. Potential side effects include blurry vision, burning, and stinging.

How Does Xalatan Work?
Xalatan belongs to a group of medications known as prostaglandins. Medications to lower eye pressure usually work by either decreasing the amount of fluid produced in the eye or by increasing the fluid drainage out of the eye. Either way, the result is the same -- lower eye pressure.
Xalatan works by opening the channels that drain fluid from the eye. By reducing eye pressure, the medication can help prevent damage to the optic nerve (and the vision loss that accompanies such damage) caused by high eye pressure.
