Rhinitis medicamentosa (rebound from decongestant sprays)
A blocked nose caused by long-term use of over-the-counter decongestant sprays. Stopping is the cure, and it is more manageable than most people fear.
Rhinitis medicamentosa is rebound nasal blockage from prolonged use of decongestant sprays such as Otrivine or Vicks Sinex. A spray that gave instant relief during a cold is now needed several times a day, works for shorter periods, and the nose is more blocked between doses than it ever was at the start.
How it presents
- A nose that feels more blocked than ever despite regular spraying
- Needing the spray more often, with each dose lasting less time
- Mouth breathing and disturbed sleep
- A history of daily spray use for weeks, months or years
Why it happens
After a few days of regular use the blood vessels in the nasal lining become less responsive to the drug, and each time a dose wears off they swell back more than before. The rebound drives the next dose, and the cycle keeps you spraying. Used for under a week, these sprays are safe; the problem is the duration.
Assessment and treatment
The history makes the diagnosis, and examination with a small endoscope confirms it while looking for the original problem that prompted the spray. Treatment is a structured six-week plan: potent steroid drops to settle the lining while the decongestant is tapered rather than stopped dead, then a maintenance spray with daily saline rinses. The first week is the hardest and the lining is usually back to normal by six weeks, after which the original cause (allergy, a deviated septum, sinusitis) is treated on its own merits. Mr Gane provides the full plan as a step-by-step sheet.
