    Alphagan (Brimonidine) Information

    What is the dosage of Alphagan?

    Alphagan comes in different strengths containing brimonidine tartrate ophthalmic solution. Alphagan has a strength of 0.2% brimonidine tartrate while Alphagan P is found in a strength of 0.1% and 0.15%. Low strengths of 0.025% can be found in an over-the-counter brimonidine product called Lumify.

    For treating elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension, one drop of the solution is instilled in the affected eye three times a day or every 8 hours. A doctor will determine the strength and dosage that is necessary to treat your specific condition.

    How Alphagan works?

    Alphagan is a relatively selective alpha-2 adrenergic receptor agonist. This ophthalmic solution, when applied to the eye, lowers fluid pressure. It works by increasing fluid drainage from within the eye and reducing the overall amount of fluid formed in the eye.

    Glaucoma symptoms are usually caused by a buildup of fluid that flows through the eye. Fluid build-up occurs because the drainage of fluid is blocked. Pressure rises as fluid continues to enter the eye, which can cause eye damage.

    What Alphagan is used for?

    Alphagan is an alpha-2 adrenergic receptor agonist. It is used to treat open-angle glaucoma or ocular hypertension with symptoms of elevated intraocular pressure. If glaucoma is left untreated, it can lead to blindness.

    It is one of the most common causes of blindness. Damage can progress so slowly that a gradual loss of sight is noticeable. Even normal eye pressure may damage the back of the eye.

    It is used to lower raised pressure in the eye; this lessens the damage to it. It prevents the risk of vision loss, nerve damage, or blindness caused by this elevated fluid pressure.

    Before it's prescribed

    Glaucoma does not typically show symptoms until it has developed in later stages. The only method of diagnosis is to have your eye pressure, optic nerve, and visual field checked by an optometrist. Talk to your doctor about other eye drops you are already taking.

    It can be used either alone or in combination with other medicines. Make sure to inform your doctor about all the medications you have or existing medical conditions that may cause drug interactions or adverse reactions occurring. Severe heart disease, blood vessel diseases, blood circulation disorders, depression, and Raynaud's disease may be monitored during treatment.
