Alphagan P (brimonidine tartrate) Ophthalmic Solution is an antiglaucoma medication used to treat open-angle glaucoma or ocular hypertension (high pressure inside the eye). Some strengths of Alphagan P are available in generic form. Common side effects of Alphagan P include eye discomfort/itching/redness/burning/stinging, feeling like something is in your eye, blurred vision, redness of the eye or eyelid, swollen or puffy eyes, sensitivity to light, nausea, upset stomach, headache, dizziness, muscle pain, dry nose or mouth, drowsiness, tiredness, sleep problems (insomnia), or unusual or unpleasant taste in your mouth.
The recommended dose of Alphagan P is one drop in the affected eye(s) three times daily, approximately 8 hours apart.

The following reactions have been identified during postmarketing use of brimonidine tartrate ophthalmic solutions in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made.
