Zaditor is another prescription allergy eye drop I got after I tried Panatol for a while. But now, the Zaditor seems like it isn't much either. Watery eyes have been bad for me this year - nothing is helping and it seems like everyone who have allergies are getting hit hard. Taking Benadryl every 6 hrs. seem to help for a while, then Chlor-Trimeton. Clarintin didn't do anything for me, even taking it everyday. Aside from the watery eyes, the skin on the corner of my eyes hurt and the skin looks like crap!
