I have been using nasal spray for 5 years , havnt gone a day without it.. Will nasacort help quit?

Yes, it can help. I am a person who CANNOT stand to feel congested! I get reliant on nasal spray from time to time, even knowing they can do this and yes, Nasacort may help, but really, it is just substituting one nasal spray for another. Nascort has a topical steroid in it so it can help soothe those inflamed passages and it may help you at least get off the 12hr sprays. At some point, then, you can wean yourself off the Nascort. One way I have gotten off 12 hr sprays is to try to wean down. I can stand a stuffy nose better during the day than at night so I try not to use them in the day then use as small a squirt as possible at night then I go to using it in only one nostril. As long as one nostril is open, I can breathe. It takes about 3 days to a week for the rebound swelling to go down and when that happens, I stop the spray in the other nostril. These 12 hour sprays work by shrinking blood vessels and tissues so when you stop them, they swell more than ever in a condition called "rebound" swelling.

Your nose is suffering rebound when you don't use it. Nasal sprays aren't harmless and should not be used long term for that reason. I would see an ENT dr and see what he recommends. Nasocort is just another spray and it too can have the same effect, plus it can thin the membranes in your nose.
