The funny thing is that just such a method does NOT work on the cause. It only "turns off" a specific reaction, OVERLOADING the immune system. From the point of view of classical pathophysiology, this approach does not stand up to criticism.
P.S. I don't understand why other answers are missing from this question. The bias of moderators and the presence of "unwritten rules" are a BOLD MINUS to the project.
I will add to what Eugene wrote.
I took a course of such immunotherapy. For about two years, on average, twice a week, they gave me injections in the shoulder (excluding the period of exacerbation).
Bottom line: it didn't help me (I'm allergic to grass pollen). I did not notice a noticeable effect.
Perhaps the period of treatment should have been even longer.
I will add that I was treated free of charge at the expense of the state in a university clinic.
Actually, there is such a thing - it's allergen-specific immunotherapy. It consists in the introduction of subcutaneous (or sublingual) increasing doses of antigen (allergen). When the concentrations become very high, the body's response to the allergen changes and the allergy itself disappears - after treatment it can take years.
This is perhaps the only therapy aimed not at the symptoms, but at the disease itself, "the disease -modifying therapy ", if in a smart way.
There are disadvantages - not all allergies are treated, they are not common in Russia, etc.
Reactions to pollen and house dust can be treated. And also on the poison of stinging insects.
The cost of such injections in the United States is $ 1000 per year. You need to look in Russia ...
No. To get rid of allergies, you need to eliminate the allergen. There is, of course, an option to sit all your life on antihistamines - the cost of suprastin is how much it will cost. But this, nevertheless, is not a treatment, but only relief of symptoms
Grandfather has been suffering from this disease for a long time, he is constantly on medications. Are there any new methods of treatment? I want to take him to my place in Moscow, where is it better to turn?
