Are lubricating eye drops safe for people using Lantanoprost for glaucoma?

Yes, lubricating drops are completely safe for those with glaucoma and those using Latanoprost, but there are two things to keep in mind. First, as always with over-the-counter lubricating drops with preservatives, you want to limit your usage to 4-6 times per day, since the preservative itself can begin to irritate the eye. And second, your usage of lubricating drops and glaucoma medications should be separated by at least five minutes, in order to avoid diluting or washing out the glaucoma medication.
