The patients also should be familiar about the immuno therapy. Not every patient with allergies finds himself suitable to an immuno therapy. Some need medical treatment. In case of perennial rhinitis, they may have to undergo maintenance treatment. Medical treatment available for respiratory allergies involves inhalation of steroids through nasal sprays.
Many people feel frightened to use nasal sprays that have steroids.
However, the effect of these steroids is confined only to local area. The steroids go only into the lungs. Very little goes outside the area of application. Those who have severe allergies need to take antihistamine tablets. Side affects due to immuno therapy can be mild and severe.
