allergic rhinitis
"I was recently prescribed this when I went to the doctor for a SEVERE (migraine-like) sinus headache. It is expensive but totally worth every penny! It works right away - you can feel the congestion/stuffiness breaking up immediately! I take this 2 times per day along with Allegra D-24 hour 1 time a day. I went from having the severe sinus headaches every single day to getting one maybe once per month. I also posted under the Allegra category - that works wonders!"
