Symptoms are primarily nasal congestion and postnasal drip. Diagnosis comes after negative skin tests and nasal smear negative for eosinophils. Some people develop the complication of an acute or chronic bacterial sinus infection, usually associated with blocked sinus drainage. The diagnosis of an acute or chronic sinus infection is confirmed by an abnormal sinus X-ray or CT scan. This type is associated with long-term use of decongestant nasal sprays or recreational use of cocaine.
Symptoms typically are nasal congestion and postnasal drip.
A person who has taken a decongestant nasal spray for months or years is using this treatment inappropriately. These medications are intended for short-term use only. Over-use can cause rebound congestion, which leads to increased nasal obstruction. It is very important for a person with rebound congestion to work closely with a physician to gradually withdraw the nasal spray. This is most often associated with a deviated septum or enlarged adenoids.
