Alphagan Dosage

When treating high eye pressure or glaucoma, the guidelines for using Alphagan are the same for everyone -- one drop in the affected eye three times daily. If your eye pressure is not under control, your healthcare provider may recommend an additional eye medication; it is generally not recommended to increase the dosage amount of Alphagan.

An Introduction to Dosing With Alphagan

There is only one standard dose of Alphagan® (brimonidine tartrate), regardless of your age, weight, or the severity of your eye condition. As is always the case, do not adjust your Alphagan dose unless your healthcare provider specifically instructs you to do so.

Standard Alphagan Dosage

Alphagan comes in the following strengths and forms:
  • Alphagan 0.2% (in generic form only) -- available in 5, 10, and 15 mL bottles
  • Alphagan P 0.1% -- available in 5, 10, and 15 mL bottles
  • Alphagan P 0.15% -- available in 5, 10, and 15 mL bottles.
The differences between Alphagan and Alphagan P are the strengths and the preservatives.
The recommended Alphagan dosage for treating glaucoma or high eye pressure is one drop in the affected eye(s) three times daily, with about eight hours between doses, using any strength or form of the products (including original Alphagan or either strength of Alphagan P).
It is generally not recommended to increase the dosage beyond the standard recommended amount, even if your eye pressure remains high. If this amount does not adequately lower the pressure in the eye, your healthcare provider may add another type of eye medication.
All Alphagan products appear to be similar in terms of effectiveness.
