Immunotherapy, often referred to as desensitization, is the only causative treatment of allergy. Immunotherapy is a well-established treatment for certain severe allergies, and involves the administration of gradually increasing doses of allergen extracts over a period of years. Immunotherapy is highly efficient when applied in a correct and methodical manner.
As time goes by, its effectiveness becomes higher and higher. One of the most important benefits of immunotherapy is that it prevents the evolution of allergic rhinitis into allergic asthma. That’s why it should be applied as soon as possible after the outset of an allergy.
Immunotherapy vaccines are administered either subcutaneously (as an injection) or sublingually (under the tongue, as sprays). The period of immunotherapy depends on a number of factors such as the type and the intensity of allergy, the patient’s age, the substance causing the allergic reaction.
