Allegra
"Works much better than other over the counter medicines. My allergy came back this time of the year, and this year got worse. My sneezing won't stop even to the point I get nosebleed. So I tried Allegra, it did suppressed all the sneezing for hours, however my nose still somewhat congested. When they mean "non-drowsy", they really mean it. I took other over the counter allergy medicines before, which they listed as "non-drowsy", but I constantly found myself falling asleep every now and then."
