Abstract
Rhinitis medicamentosa (RM) is a drug induced non-allergic rhinitis associated with prolonged use of topical nasal decongestants. This review discusses the nasal mucosa microcirculation, basic pharmacology of topical decongestants and the theories of the pathophysiology of RM. Diagnostic problems are discussed in addition to the current opinion on how to treat RM.
