Rhinitis is a condition where the mucous membrane in the nasal cavity is inflamed.
It is a common condition that may be caused by an infection, an allergic response or even overuse of certain medications.
Infective rhinitis is usually caused by viruses and results in the common cold.
Infections usually resolve on their own over a few days. Medical treatment is usually targeted at symptom relief. Antihistamines or nasal decongestants may be prescribed to alleviate symptoms of the disease.
Nasal decongestants like oxymetazolin, work by constricting the blood vessels in the mucosal lining. It is important to note that prolonged use of such decongestants may result in rebound symptoms (return of symptoms being treated which is now more severe than before) and worsening of the nasal obstruction. This is a condition known as rhinitis medicamentosa.
