[This review was collected as part of a promotion.] I took them day and night and it does not make me sleepy or interrupt my routine, it acts fast and the effects last for a long time.

[This review was collected as part of a promotion.] Xyzal cleared my allergies right up! and for hours i was symptom free! it really did work wonders.

[This review was collected as part of a promotion.] Taking this at night allowed me to sleep better as I could breathe with less congestion and stuffiness. My nose was alot clearer in the morning allowing me to breath deeply and more easily.

tried the free sample pack they advertised. Seemed to work great so I purchased a bottle. Do not take everyday but only when I notice allergies affecting me.

[This review was collected as part of a promotion.] I tried this product for the full 5 days and in the height of allergy season. I have made the full switch to this product leaving my old allergy medication in the trash

[This review was collected as part of a promotion.] I'm allergic to dust and pollen. It's not super severe but this helped me a lot. Usually allergy medications can make you drowsy but Xyzal didn't.

[This review was collected as part of a promotion.] I felt it working pretty quickly. I will switch over once my current bottle of allergy meds are done.

[This review was collected as part of a promotion.] XYZAL is a good allergy medicine. Because of Texas's hot and cold weather ,I have got allergies frequently. I got this medicine at the right time. I ate for 2 days and I was better on the 3rd day.

[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.

[This review was collected as part of a promotion.] Great product that does exactly what it says that it will do. Very quick acting. I have told my whole family and friends about the product. I went and bought more.
