Brimonidine

brimonidine

Brimonidine is a medication most often used as an eye drop to lower pressure inside the eye. It works by activating certain receptors in the eye that decrease the amount of fluid produced and can also help fluid drain away more easily. Beyond its pressure-lowering effect, researchers have explored whether it might help protect nerve cells in the eye, though that protective role is still being studied. People commonly use brimonidine to treat conditions where high eye pressure could damage the optic nerve. It is usually applied two or three times a day, and its effects begin within an hour or two after use. Common side effects include eye redness, dry mouth, and a yellowish or brownish stain on the eyelids in some people. Because it can affect blood pressure and heart rate, doctors are cautious when prescribing it to people with certain heart or blood pressure problems and to young children. If you wear soft contact lenses, you typically remove them before putting in the drops and wait at least 15 minutes before reinserting them. Overall, brimonidine matters because it is a widely used, effective treatment for lowering eye pressure and may offer additional benefits that could protect vision over time.
