IMMUNOTHERAPY IS THE CONTROLLED EXPOSURE OF KNOWN ALLERGENS IN PREDETERMINED CONCENTRATION TO PATIENTS OVER A PERIOD OF TIME SO THAT THE BODY WILL DEVELOP IMMUNITY TO THOSE PARTICULAR ALLERGENS.
Sublingual immunotherapy is the latest and very effective alternative way to treat allergies without injections.
Here we are giving the medication as drops under the tongue in a sugar cube(sugar cube can be avoided if patient is diabetic)
It is relatively safe and effective for treatment of allergy. reactions to slit are almost minimal or nil.
Clear guidance is given to the patient so that they can take medicine by themselves at home.doctor visit is required only at the time of dose upgradation to give test dose(that is once in one and a half month). from our clinic we can provide this in a very cost effective way.
The duration of treatment vary from person to person approximately may extend from 3 to 5 yrs.
In certain cases this may extend for couple of years and here is no harm in continuing the prolonged period since the material is natural and not having synthetic chemicals, which could harm the normal body
By this technique we are desensitising the patient to particular allergen/ allergens.
Immunotherapy produces a shift of th2 response to th1 and downregulates il-4.
This brings about the reduction in release of inflammatory mediators, specific ige levels and allergen specific ariway responsiveness which results in clinical improvement
Drug used in immunotherapy is a natural product . no chemicals are there. For eg. If patient shows allergy to pollens of neem tree (azidirachta indica) in allergy testing, we prepare extract of neem pollen and we are treating the patient with that extract in different concentrations for a period of time.
Allergen avoidance & immunotherapy have the potential to modify the natural course of disease. Immunotherapy Prevents sensitization to new allergens in monosensitized patients.
Yes we can. But not for all allergic conditions and the result may vary from person to person. For the success of immunotherapy several factors play their role. Selection of patient, selection of allergen, quality of the drug, adherence and compliance of the patient to immunotherapy etc all play very important role.
For food allergy presently avoidance is recommended . immunotherapy for food allergy is still under trial.
No.Patients on betablocker drugs and those who experienced severe reactions in prior immunotherapy should not be considered for immunotherapy. Immunotherapy fails if done by an untrained physician or done in very young ( <5 yrs) and in elderly patients( >65 yrs)
