Allegra-D 24 Hour
allergic rhinitis
"I love this.  If I don't take it, I ALWAYS end up with a sinus infection and a trip to the Dr.  When I do take it, I don't sleep as well, but I'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.  "
