Alphagan 2% (Generic)
Alphagan (Brimonidine ophthalmic) is used to lower pressure in the eyes in patients who have glaucoma (high pressure in the eyes that may damage nerves and cause vision loss) and ocular hypertension (pressure in the eyes that is higher than normal but not high enough to cause vision loss). Brimonidine is in a class of drugs called alpha adrenergic agonists. Brimonidine works by decreasing the amount of fluid in the eyes.
