RHINITIS MEDICAMENTOSA

Description : The chronic use of topical nasal decongestants produces a state of chronic rhinitis which is known as rhinitis medicamentosa. Topical vasoconstrictors apparently cause such severe constriction of the blood vessels of the nasal mucosa that ischemic mucosal damage develops. Consequently, when the vasoconstrictors effect wears off, the nasal mucosa "rebounds' becoming reddened and edematous. The patient then experiences increased nasal obstruction and reapplies the decongestant thereby establishing a vicious cycle. On examination, the nasal mucus membranes are usually fiery red and swollen. The history of topical decongestant abuse is usually freely given.
