Do you mean do the side effects go away eventually if you keep taking it? If you are still on it, you will still experience these effects, so far as I know. If you quite taking it you will get improvement. After a couple of weeks I felt improvement, but it still took months. Some other people who have posted on this site have, however, had it go away in days after stopping Flonase. I hope this helps.
I was recently prescribed Flonaze nasal spray. For about a week now I have felt the need to need to take more of my low dose blood pressure meds at night because after I do my Flonaze nasal spray in each nostril my heart rate seems to go out the roof at bed time every night making me scared to death to fall asleep. I'm afraid I'm going to have a heart attack because my heart I beating so fast. It DOESN'T do this during the day. I told my husband last night I feel like this only at bed time right after I take my Flonaze one spray to each nostril. So I was going to Google Flonaze tomorrow & not take it tomorrow so I can start taking it in the mornings instead of at night but now I know it's the Flonaze so I refuse to take it anymore nomatter how well its been working for me. I cant stand how i feel from my heart racing so fast afterwards of using Flonaze navel spray.
