This is taken before bed and can definitely leave you feeling tired. Does a decent job of controlling allergies. I do feel like sometimes it dries my sinuses out.

[This review was collected as part of a promotion.] Xyzal lasts for 24 hours which I loved, and, it works on several different symptoms like sneezing, runny nose, itchy eyes, and an itchy throat - for all of which I needed relief.

I got a sample of it in the mail and decided to try it my allergies have been so bad this year! I honestly slept so good that night that I went and bought it the next day.. it has helped me clear up and be able to breath again!

[This review was collected as part of a promotion.] I don't like the allergy relief that i was taking since it was making drowsy and less productive through out my day. This was not the same so i will continue to give it a try.
