I suffered from pretty terrible Fall and Spring allergies for most of my life. I finally went to an allergist and he put me on a combo of Nasonex (nasal spray), Xyzal (pill), and Pataday (eye drops), and it's now as if I don't have allergies. All three are prescription only. I have never had any side effects. If you visit the medicines' websites there are coupons and incentive programs available for all three that dramatically reduce the cost. Good luck.
