Pls advice me how long can i safely use nasonex (mometasone) nasal spray, ve used it for years now, but if stop get congestion due turbinate swelling and brain fog?

Long term: Intranasal steroid sprays like Nasonex (mometasone) are safe for long term use and not known to cause rebound symptoms when stopped. Instead consider that you may be exposed to allergens or irritants that are causing symptoms and held at bay by the medication. While off the med, symptoms worsen. Consider seeing an allergist for testing to determine why you need Nasonex (mometasone) in the first place.

Safe for years: It is very safe to use in long term studies. Many pts end up taking this for years as well with minimal to no side effects. If looking for another long term option, then allergy shots might work well for you, and possibly lessen your need for medications.
