Zaditor effectiveness?

I have been using Zaditor for about 4 weeks. It seems to work in an improvement sense, but still hasn't solved my problem. It is a very expensive cure, and I still don't know how long I have to maintain the treatment.

Pain Relief

I had severe pain in my eyes from "drt eyes" several days a week and was given several eye drops to try by my ophtholmologist and allergist. Finally I tried Zaditor and have no more pain. I am very greatful.

No Subject

I have had a lot of problems with itchy, watering, sore eyes over the years, and tried everything imaginable to get me through allergy seasons. Everything I used made my eyes burn, and I sometimes wondered if the cure was worse than the symptoms.
Then my doctor had me try Zaditor. When I found out the price I
nearly fainted...I thought twice about filling the RX,believe me.
But I have found that they are gentle on my eyes, no burning at all when I put them in. I dont use them every day...only on my bad allergy days, wish they were less expensive!
