I've tried every OTC allergy med out there and this one is the best by far! Works so quickly and keeps my allergies at bay. Sometimes I'll still have symptoms (my allergies are pretty bad), but it works so well that I notice when I skip a dose!

[This review was collected as part of a promotion.] I would not buy. It kept me sleepy and groggy. I never help my allergy symptoms in the night or the next day. I tried the product several time but no real relief

[This review was collected as part of a promotion.] It relieved my allergy symptoms almost immediately and lasted just about he 24 hrs as said on the box. I was able to get a good night sleep since my allergy symptoms were kept in abeyance.

[This review was collected as part of a promotion.] I swapped another medication with this and had no issues. Xyzal picked up where it left off just fine. Nothing was out of the ordinary and I barely noticed I was using something new.

This doesn't work for 24 hours. As a person who has both indoor as well as outdoor allergies, Iam STILL looking for a long acting allergy option. Unfortunately this one is NOT it!

[This review was collected as part of a promotion.] Used this sample when allergies started, went out and purchased to take everyday during allergy season works wonders.

[This review was collected as part of a promotion.] Xyzal really does last 24 hours. It helped me get back to feeling normal which is hard to do this time of year with all the pollen in the air.

[This review was collected as part of a promotion.] I received a Xyzal trial package last week and am really pleased with it. It helped me deal with my allergies swiftly. The redness and itching vanished almost immediately after the first dose.

[This review was collected as part of a promotion.] Works wonderfully. I like that I can take it at night (it made me very drowsy) and wake up refreshed and ready to go the next day without the grog I get with most allergy medicines.

[This review was collected as part of a promotion.] Have been using this medication for a while now and to tell you it is the best allergy product I have so far tired and it work great. Will definitely buy again, once it finished.
