I wasnt sneezing all day but my nose was stuffy & runny so i tried astepro for the first time & i cant stop sneezing. ive been sneezing almost constantly for hours. my eyes are tearing, my throat is sore & my sinuses are still messed up. why??

You are probably allergic to an ingredient of this nasal inhaler although it is used for allergic rhinitis. I can't rule out the possibility of allergic to azelastine, the main chemical ingredient. You should irrigate your nose with saline or fresh water for getting rid of any residual. If you want you can try steroid nasal inhaler, flonase or nasonex, after nasal irrigation. Good luck.
