Specific immunotherapy involves the administration of allergen injections in increasing doses to reduce the susceptibility of the allergic person to these allergens.
Allergy is an overreaction of the immune system when the body is exposed to a substance that it believes is a harmful agent. That’s why some people are allergic to animal hair or mites, for example, while others aren’t. People most likely to have allergies are those with respiratory diseases such as asthma, rhinitis or sinusitis.
- Therefore.
- Specific immunotherapy is a good treatment option for people with allergic diseases such as allergic rhinitis.
- Allergic conjunctivitis.
- Allergic asthma.
- Allergic reactions to the poison from insect bites or other IgE-mediated hypersensitivity diseases.
The allergy vaccine should occur for each person, individually. It can be applied as an injection or as drops under the tongue and contains increasing amounts of allergen.
Allergens to be used in specific immunotherapy should be selected on the basis of allergic tests, which allow for qualitative and quantitative assessment of allergies. Your doctor may order tests such as an allergic skin reaction test, a blood test called REST, or Immunocap to find out exactly what allergens are for that person. Find out how this test is performed.
A dose inicial deve ser adaptada à sensibilidade da pessoa e depois as doses devem ser aumentadas progressivamente e administradas em intervalos regulares, atºe se atingir uma dose de manutenção.
The duration of treatment may vary from person to person, as treatment is individualized.These injections are generally well tolerated and do not produce significant side effects and, in some cases, rashes and redness may occur.
Immunotherapy is indicated for people with over-allergic reactions that can be controlled. People most suitable for this type of treatment are those with respiratory allergies such as asthma, allergic rhinitis, allergic conjunctivitis, latex allergy, food allergies or reactions to insect bites, for example.
Treatment should not be performed in people with corticodependant asthma, severe atopic dermatitis, pregnant women, people under 2 years of age and the elderly.
