[This review was collected as part of a promotion.] I tried this sample. It did work, but made me very sleepy for a very long time. I did not complete the sample as I did not like this aftereffect.

[This review was collected as part of a promotion.] This stuff is highly effective, but I think it's to be saved for bad bouts vs every day use. I could immediately feel relief, but at the same time I had the full brunt of adverse reactions.

[This review was collected as part of a promotion.] I started using this allergy medicine at the beginning of spring. It is by far one of the best allergy medicines out there.

[This review was collected as part of a promotion.] I got a sample in the mail, my sister came over sneezing, runny nose so I gave my sample to her to take. I’m sure it helped here…. Thank you for the sample.

[This review was collected as part of a promotion.] I tried this when my nose wouldn't stop running and I couldn't stop sneezing. It worked really well for me.

I received a sample of xyzal and when I ran out of the allergy medicine I usually use I tried this and was pleasantly surprised at how effective it was.

[This review was collected as part of a promotion.] If it wasn’t because of the sample I never would have tried Zyzal. I am very glad I took it and felt great
