Quick overview

Alphagan Eye Drops contain brimonidine tartrate, an alpha-adrenergic agonist used to lower high pressure inside the eye and treat glaucoma. They work by reducing the amount of fluid the eye produces and helping fluid drain out more easily. Alphagan is used to treat open-angle glaucoma and ocular hypertension, either alone or together with other eye pressure-lowering medicines.

What is Alphagan Eye Drops

Alphagan is an eye drop containing brimonidine tartrate. It is used to lower high pressure inside the eye and to treat glaucoma.

Alphagan Eye Drops uses

  • Lowering raised pressure in the eye(s)
  • Treating open-angle glaucoma
  • Treating ocular hypertension

Benefits of Alphagan Eye Drops

  • Helps control eye pressure to reduce the risk of damage to the back of the eye and vision loss
  • Can be used alone or together with other eye drops/medicines to lower eye pressure

How Alphagan Eye Drops works

Alphagan lowers pressure in the eye by reducing the amount of fluid the eye produces and helping fluid drain out of the eye more easily.

Alphagan Eye Drops dosage

Use the eye drops every day at about the same time each day unless your doctor tells you otherwise. If you use other eye drops too, wait at least 5 to 10 minutes after using this medicine before using the other drops. Remove soft contact lenses before putting the drops in, and wait 15 minutes afterward before putting lenses back in.

Wash your hands well with soap and water before and after using the drops, and shake the bottle gently before use. Sit or lie down to make it easier to put the drops in your eye. Tilt your head back, look up, and gently pull down your lower eyelid to form a pocket, then release one drop without letting the bottle tip touch your eye or eyelid.

Close your eye without blinking or rubbing it, and press a finger against the inside corner of your eye near your nose for about two minutes to stop the medicine draining into your tear duct.

If you forget a dose, use it as soon as you remember, but skip it if it is almost time for your next dose — do not double up.

Children 2 years of age and older, especially those weighing 20 kg or less, should be treated with caution and monitored closely by a doctor. Do not use in children younger than 2 years of age.
