Mometasone is a corticosteroid nasal spray that helps reduce inflammation in the nasal passages. It works by decreasing swelling and irritation in the nose, making it easier to breathe. In this trial, it is used as part of a withdrawal plan to help patients who have become dependent on nasal decongestants.

Nasal decongestants are medications that provide temporary relief from nasal congestion by shrinking swollen blood vessels in the nasal passages. While effective for short-term use, these medications can lead to dependence when used for extended periods, which is why this study focuses on helping patients reduce their overuse of these products.

Rhinitis Medicamentosa – A condition that occurs due to prolonged use of nasal decongestant sprays, typically lasting more than 5-7 days. It is characterized by a rebound nasal congestion that develops as a result of overusing topical decongestants. The condition creates a cycle where the person experiences increasingly severe nasal congestion when the decongestant wears off, leading to more frequent use of the spray. Over time, the nasal tissues become less responsive to the decongestant, requiring more frequent applications to achieve the same effect. The nasal mucosa may become swollen, red, and chronically congested.
