The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Proper use of Alphagan P

Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

If your doctor ordered two different eye drops to be used together, wait at least 5 minutes after you put the first medicine in your eye to use the second medicine. This will prevent the second medicine from “washing out” the first one.
