allergic rhinitis
"I had been on Allegra for allergies for almost 10 years. This year it stopped working and began to make my heart race. I also developed new allergies (to foods). My general practitioner mentioned Xyzal to me, gave me some samples, and instructed me to start out with the pediatric dose 2.5mg to see how I reacted to the medicine and how effective it was for me. All I can say is, it's AWESOME! It is fast acting, stopping the itchy nose, throat, ears and non-stop sneezing soon after taking it. No crazy heart rhythms, hung over feelings, or depression with this antihistamine. It's a keeper!"
