I have lost my sense of smell since May 2005. I went to the Dr. on May 24th ,I was given a prescription of Nasonex to take twice daily one sqirt per nostral, and shortly after that witin a 10 day period, I lost my sense of smell. The ENT specialist was concerned at how quickly I lost my sense of smell. He ordered a cat scan for me to see if there is any blockage. Upon reading on this website, about another person that has had the same side effect I am beginning to believe that Nasonex could be the cause. I have stopped taking this as of today. Last dosage was this morning.
