Alphagan® P (brimonidine tartrate) is part of a group of medications called alpha adrenergic agonists (often known as just "alpha agonists"), and is used to treat high eye pressure in people with open-angle glaucoma or ocular hypertension. This prescription medicine works to lower eye pressure by decreasing the amount of fluid produced by the eye and increasing the rate of drainage. It comes in the form of eye drops and is used in the affected eye(s) three times daily. Potential side effects may include eye redness, itching, and allergies.
