unusual facts about rhinitis medicamentosa


Rhinitis medicamentosa

Rhinitis medicamentosa (or RM) is a condition of rebound nasal congestion brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) that work by constricting blood vessels in the lining of the nose.


Nasal congestion

Topical decongestants should only be used by patients for a maximum of 3 days in a row, because rebound congestion may occur in the form of rhinitis medicamentosa.
