Rhinitis medicamentosa
Rhinitis medicamentosa, also known as rebound congestion, is severe nasal congestion caused by the overuse (over 3 days of continuous use) of decongestant nasal sprays and drops (not from steroidal sprays). Treatment is by discontinuing the medication that is causing the condition and using a saline nasal spray. Corticosteroid nasal spray may also be used if needed.
