Allergic Rhinitis
"I love this.  If I don&#039;t take it, I ALWAYS end up with a sinus infection and a trip to the Dr.  When I do take it, I don&#039;t sleep as well, but I&#039;m not tired in between.  My major issue is that I am always constipated when I take Allegra-D and my periods are excruciatingly painful.  "
