Works best when combined with Zyrtec! Xyzal at night, Zyrtec in the morning. By themselves, they are not strong enough. But together, Wham! (I did get permission from my allergist first!)

[This review was collected as part of a promotion.] I have been using Xyzal for a couple of years now and I have to say it works great. It starts working fast and when taken daily, it really helps clear up allergies. I love it.

[This review was collected as part of a promotion.] This product really helped my allergies. My itchy eyes and runny nose were gone after just one pill. It works fast and I like how it lasts for 24 hours.

[This review was collected as part of a promotion.] i have not bought this as of yet, i just recently received my free sample, so i will try this out first, & see how it works on me.

[This review was collected as part of a promotion.] I received a sample to try for a week. It did help my allergy symptoms so I woke up headache and sneeze-free. My challenge was that I felt tired and sleepy for several hours the next day.

[This review was collected as part of a promotion.] This product does cause you to feel drowsiness so it shouldnt be used when you need to stay alert! I would say the pill kicked in fast as I stopped sneezing after a while.

I recently requested a sample of Xyzal because I wanted to try something that would not give me a headache. Xyzal relieved my allergy instantly without the headaches.

[This review was collected as part of a promotion.] It was ok. Didn't really help sleep through the night, was still congested. I've used better products. It did help a little but I wouldn't buy it.

[This review was collected as part of a promotion.] These work well. My allergies have never been contolled like it has been since starting xyzal. They work quick and last the whole twenty four hours.

[This review was collected as part of a promotion.] The XYZAL Allergy 24HR was very good! I tend to take allergy medicine on days where pollen is the worst, and in fact, this helped me a lot! I definitely recommend it to other people.
