Alphagan P Eye Drops are made up of brimonidine, which is an alpha agonist drug. This medication usually comes in a white and green box with an aqua and white bottle inside. This product can be purchased as its brand name Alphagan P or as its generic alternative, brimonidine, in 0.15% strength.

This medication is used for both open angle glaucoma and ocular hypertension. Glaucoma is an eye disorder caused by fluid buildup in the eye, which results in vision loss and extra pressure on your optic nerves, causing them damage. Ocular hypertension causes glaucoma as it causes the pressure in your eyes to be higher than normal, and fluid cannot drain.

Brimonidine works by reducing the amount of fluid created in the eye while helping the flow of fluid.
