What is rhinitis medicamentosa?
Rhinitis medicamentosa is nasal congestion and sneezing that arises with the overuse of medication for treating nasal symptoms. This is also known as rebound rhinitis. Although this is a short-lived reaction in some cases, it can have permanent effects such as chronic sinusitis. Typically the overuse stems from a pre-existing chronic nasal problem and eventually the patient believes that the underlying problem is worsening. This compels a person to continue using the nasal decongestant and sometimes even increasing the dosage on their own, thereby further aggravating the condition.
