allergic rhinitis
"This drug helps with my nasal symptoms but it makes me drowsy, might be because of other medications I take on a daily basis (Cymbalta and Stahist).  It has helped with my symptoms because if I don't use it, along with Flonase, I get headaches and stuffiness.  I'm happy with it and will continue using it.  Hopefully the drowsiness effect will get better with time.  It did when I used to use Asteline."
