Alphagan P is an eye drop solution prescribed to patients with open-angle glaucoma or ocular hypertension. This medication is also known by it's generic name Brimonidine Tartrate as an opthalmic solution 0.1% and 0.15%. Alphagan P works to reduce production of eye fluid between the back of cornea and the front of the gel tissue filling the eye behind the lens.

To use Alphagan P take one drop in the effected eye(s) three times a day eight hours apart. In some cases glaucoma patients use more than one opthalmic solution to reduce pressure in the eye. If more solutions are required or prescribed, give at least five minutes before applying a different solution to the effected eye(s). Take care to avoid contaminating the solution. Make sure to wash your hands before use, and do not let the tip touch the eye or any surface.

Alphagan P can interact with some MAOI's (antidepressants) and a variety of conditions.
