I have been using Alavert dissolving tabs for years now. My allergies are usually extreme, with excessive sneezing, runny or congested nose and head, itchy eyes and occasional wheezing. For all of the above symptons, Alavert will unfortunately NOT do the trick. Prescription Allegra will be the best bet. However, if you do have any of the syptoms listed on the box, like runny nose, the Alavert will work and the quickly dissolving tabs are very convenient. The original mint flavor as well as the citrus mint are both good; not delicious, but very tolerable!
I have found that taking 2 will help better with more extreme symptoms. I resorted to this when I did not have Allegra. Taking 2 did cause drowsiness, however.
Overall, I would recommend Alavert for milder symptoms. They are easy and quite convenient!
