allergic rhinitis
"My ENT prescribed this for me and it is so totally amazing.  I have not had headaches, or drowsiness as mentioned by others.  I must be using it properly because I have never tasted it.  All I know is my nose is not running all the time, I don't have to always have a tissue in my hand and I can go for walks without having to pay the consequences of being outside.  It is expensive, but I'm worth it!  LOL"
