H.F.
I don't know for sure what will work for you. I know that I've tried Opcon-A and it has worked for me. But I'm not on prescription eye drops and I don't wear contacts. The reason I don't wear contacts is because one of my eye doctors told me that the problem with contacts is they hold the allergens against your eye which can make the problems worse
For my allergies, I've used Claritin, Benadryl, Allegra, and a few other different medications at different times. I've had allergies since I was a baby. Usually, the oral medications take care of most of my symptoms. As I mentioned above, on the few occasions they didn't, I tried Opcon-A and that worked for me.
Good luck. I hope you find something that works for you.
