Specific desensitization to respiratory allergens is a way to “train” the body to become less allergic depending on the type of antigen causing the allergy. This is an immunotherapy that helps prevent common allergic reactions in the respiratory tract such as grass pollen, house dust...; thereby helping to reduce the typical inflammatory symptoms for people with allergic rhinitis and asthma.

Some people are very anxious about flying, while others may become extremely fearful at the thought of flying and refuse to go anywhere near an airplane. Systematic desensitization is a behavioral technique in which a person is gradually exposed to an anxiety-provoking object, event, or place while simultaneously engaging in some form of relaxation to reduce anxiety symptoms.

Desensitization plays an important role in medicine, helping patients to be able to use drugs that they were previously allergic to. However, this method is only temporary, so when it is necessary to use the same drug that caused the allergy, this method must be repeated.
