Alphagan P Ophthalmic Solution

What is this medication for?

Brimonidine belongs to a family of medicines known as alpha adrenergic receptor agonists. It works by keeping blood vessels in the eye from narrowing. This reduces the pressure inside the eye.

Brimonidine is used to treat open-angle glaucoma and ocular hypertension, conditions caused by high pressure inside the eye.
