Key Point: Allergic rhinitis and asthma go hand-in-hand. If a patient comes to us with one condition, we should actively look for the other. Treating the co-existing asthma or allergic rhinitis improves the quality of life of the patient.

      duration depends on the intensity of patients symptoms and how long the symptoms are present, the drug can be reduced and stopped as the patient improve over months or years. some may need it life long. It can be given to any one including children above 6 months (http://www.medicinenet.com/montelukast/article.htm)

    In my experience as a pediatrician as well as asthma & allergy specialist, I have got good results in treating allergic rhinitis with steroid nasal spray combined with monteleucast & levocetrizine. This can be gradually over a period of 6 months.

    I meant this combination can be tapered gradually over a period of 6 months.
