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.
If a big wheal appears, the doctor opts for reducing the doseage. Severe side affects can lead to bronchial asthma and a shock. Patients should be aware that immuno therapy is not a single shot treatment. Allergies are a chronic problem and they can be over come by proper treatment. Patients should receive maintenance doses for a long time.
