Any advice on medication for chronic dry eyed?

OTC lubricants: Most dry eye can be handled with over the counter (otc) lubricating drops. Do not use the ones that say "gets the red out" as these are drying. Plain eye ointment at night is also helpful. For persistent eye dryness especially if the vision is impaired, see your ophthalmologist.

Many options...: If you are already using artificial tears 2 or more times daily without relief, you can ask your doctor about restasis, a prescription medication to help produce good tears. You may also try treating the eyelid oil glands that can contribute to dry eye, by using warm compresses, lid scrubs and vitamin supplements with omega 3 fatty acids. Discuss these options with your doctor. Good luck!

Many treatments: I recommend fish oil at least 2000 mg a day for dry eyes. Restasis is also helpful, but takes 3-4 months to take full effect. For very severe dry eyes, there is a medication called Lacrisert (hydroxypropyl cellulose). Autologous serum tears are another "medication" but is harder to find a place that does it.
