As an allergy patient for at least 30 years and asthma for over five years, I think the Nasonex and the Flonase are both safe to use on a regular basis. They are very different from the nasal sprays such as Afrin that we use to have as only choices that are addictive and also have rebound effects. I can remember as far back as 25 years ago having to take steroid injections to wean myself off the Afrin and then try to make it through the 24 hours until the steroid kicked in and not use the Afrin. One of my daughters has really bad allergies and it is now looking like she may have asthma, she knows not to even buy a bottle of Afrin. I don't know if it is against forum rules to warn others against products, but please don't get into the habit of using any of those nose drops or sprays along the lines of Afrin.
