Table of contents:

Alphagan (brimonidine) eye drops are used to treat open-angle glaucoma, ocular hypertension, and to reduce pressure inside the eyes. It works by lowering high fluid pressure in the eye, which reduces the risk of vision loss.

Brimonidine belongs to the family of medications known as alpha-2-adrenergic receptor agonists. It is available in eye-drop form and is used to reduce the pressure inside the eye for people with open-angle glaucoma or intraocular hypertension (increased pressure in the eye).

Uses and Dosage

Use Alphagan eye drops as directed by a healthcare provider to avoid getting the medication in your mouth or touching the dropper tip to any surface. If you have any further questions about the use of Alphagan eye drops, you should consult with your healthcare provider directly.

To use Alphagan eye drops (Brimonidine):

  1. Wash your hands before handling the medication to avoid contamination.
  2. If you wear contact lenses, remove them before using the medication.
  3. Tilt your head back and look upward, then pull down your lower eyelid to create a small pouch.
  4. Hold the dropper directly over your eye and apply one drop of the solution into the pouch.
  5. If you need to use drops in both eyes, repeat steps 3 and 4 for your other eye.
  6. After using the medication, close your eyes for 1-2 minutes but do not blink or rub your eyes.
  7. To avoid draining out the medication, apply gentle pressure to the inner corner of your eye.
  8. Wait at least 15 minutes before putting in your contact lenses again.
  9. Do not rinse the dropper and replace the dropper cap after each use.

The usual recommended dose for adults is one drop of brimonidine 0.2% solution into the affected eye(s) twice daily, approximately 12 hours apart (e.g., in the morning and at bedtime).
