Mometasone
"About two years ago, I stayed home sick with what I thought was the flu. After about a week of misery and no relief I went to the doctor. He told me that all the awful, flu-like symptoms were actually my hay fever acting up and because I had waited too long to come in I now had nasal polyps. Many members of my extended family has had them and treated them with Nasonex or even surgery (my aunt can't taste or smell now). Since then, I've used Nasonex nearly every night. There's a very obvious difference between nights I take it and nights that I forget - I tend to wake up with throat congestion and a runny nose. Only once have I actually had a full-on nosebleed."
