allergies
"I have a cat and a dog in the house so my nose runs all year long. I had taken Benedryl daily until the doctor told me to take it twice a day cause my body had gotten too used to it. I then tried Claritin and Allegra, neither worked for me at all. I then switched to Zyrtec and that was pretty great. I still had a runny nose but not as bad. When Xyzal came out I had to try it since I had a crack in my nose for about 6 months from a runny nose. Within 1 week of taking Xyzal the crack had healed and my nose wasn't runny. This is a miracle drug for me. I believe that each body is different and you need to take the drug that works for you. I take this during the day as it wore off when I came home from work to be with my animals."
