allergies
"I was prescribed this drug when it was first introduced over 10 years ago by sanofi- Aventis,or ucb pharma. I was havening severe reactions to , indoor and outdoor allergies. dust mites, certain soaps, and food allergies. For the longest time I had to be very careful what I could eat. This product changed my life style and how I was living. By far the best allergy medicine out there, and I have taken them all. Yes it is expensive, but worth it. I have been taking  5 milligrams a day for over 10 years now, and it still works. Generic doesn't work. It's not the same. Xyzal is the best."
