Rhinitis medicamentosa: Causes, Symptoms, Treatment
Etiology: it represents a different etiology. This is a drug-induced rhinitis resulting from prolonged use (ie, >5-10 d) of nasal sympathomimetics. During this process, in the nose are gradually desensitized to endogenous and exogenous stimulation.
Symptoms: Patients with this disease typically present with extensive nasal congestion and rhinorrhea resulting from loss of adrenergic tone rather than from the original cause of rhinitis.
Normal nasal function should recover within 7-21 days after sympathomimetics are discontinued.
Treatment: Topical nasal steroid spray may ease the transition from the sympathomimetic agents, and some suggest allowing the patient to continue using the offending agent at night for a few days or weaning 1 nostril at a time.
