Immunotherapy, also known as desensitization or mortgage consciousness is a form of treatment that extracts of allergens (pollen, dust, mold, etc.) are introduced into the body to induce an immune response, resulting in reduced or possibly elimination of the allergic reaction.

Indications for immunotherapy
Not all patients allergic to the need for immune therapy. The decision about who would benefit from this treatment depends on what kind of allergy, ie what the patient is allergic are allergic and the severity of allergic symptoms. In addition, immunotherapy in patients allergic to substances that can not be avoided. The adequacy of the immune therapy will be determined after careful consideration of all these factors.
It should be noted, however, that immunotherapy, but highly effective, are not the only modality in the treatment of allergic person. Immunotherapy is only one element of a comprehensive approach that also includes environmental monitoring and any use of drugs. A balanced approach gives the patient the best chance for a solution of an allergy problem.
To understand how the immune therapy, is a brief explanation of the allergic reaction is necessary. Simply put, an allergy the immune system to overreact to things that normally would not react, such as dust mites and pollen.
Immunotherapy is meant to “reprogram” the immune system so that it no longer reacts when exposed to the allergen (s) responsible. This is achieved by repeated exposure of the immune system to allergens for a long time. As with all vaccines, like polio, tetanus, whooping cough, causes the current administration of the drug’s immune system to produce antibodies against the administered drug.
Types of immunotherapy
Traditionally, the “gold standard” of immune therapies in the form of injections of allergens in the subcutaneous tissue of the arm, called desensitization. Desensitization is currently the preferred form of immunotherapy for the majority of board certified allergists.
There was more evidence in the literature that suggests that sublingual (under the tongue) immunotherapy may be just as effective and safer than traditional allergy shots. Sublingual immunotherapy (slit) have been used in Europe for years and clinical trials are underway in the United States to establish their efficacy and safety.
What can we expect of immunotherapy
Immunotherapy is effective to reduce or eliminate allergic symptoms in the vast majority of patients are correctly placed in this treatment. In most patients, the desensitization better slow, steady and significant in six to 12 months after starting treatment. Some people have reported relief after only a few weeks or months, but this is unusual. If a patient can not get a significant improvement within 18 months, treatment should be reassessed. Most patients complete the program for immune therapy in three to five years. Most have a long-term improvement after desensitization is interrupted, which lasted for years and sometimes life.
Reactions of immune therapy
Because allergy shots contain substances that the patient is allergic, there is always a possibility, albeit small, of an allergic reaction. The reactions to immunotherapy can be divided into three categories:
It is rare that one has a little local reaction at the injection site. This is usually less swelling, redness and itching. Reactions smaller than the size of a watch is usually not significant, but we must mention the allergy nurse before the next injection. Large local reactions may indicate that the serum of the allergy is severe and dose adjustment may be necessary to repeatedly during immunotherapy.
A systemic response is defined as what happens outside the injection site and may affect multiple organ systems. Occurs rarely in the exhibition very sensitive, or when people are more natural allergens, as in people sensitive to pollen in the spring and autumn. These reactions can include generalized flushing, itching, sneezing, runny nose, hives, coughing, wheezing and breathing difficulties. Despite the very serious allergic reactions have been reported in medical literature, including reduced blood pressure (shock) and death, they are extremely rare.
The systemic reactions can almost always be avoided by recognition and prompt treatment of symptoms. These reactions are rare that all patients must wait for the doctor’s office 20 to 30 minutes after a sudden allergy.
delayed reactions are often very localized, but in rare cases, systemic. Usually begins several hours after a sudden allergy, but may be delayed up to 24 hours. These symptoms are usually mild but can include local itching, swelling and pain at the injection site, nasal symptoms, or wheezing.
Delay when immunotherapy
For a person suffering an acute allergic reaction or underway, such as fever, asthma, hay fever or hives after a further injection of allergen can increase the risk of a reaction. If you are unsure whether the injection should be done, must be consulted nurse injection and determine whether the dose should be reduced or whether the injection should be postponed.
An injection should be administered if the patient had high fever within 24 hours. If patients with asthma have difficulty breathing or wheezing, the injection should not be given. Immunization should be delayed at least 24 hours after receipt of a vaccine against influenza vaccine against tetanus, or any kind of vaccination. Avoid vigorous exercise, an hour before and one hour after a sudden allergy.
Immunotherapy may be self-administered?
The answer is simple: NO. Although the chance of an allergic reaction is very low, it is important that the plan is administered in a doctor’s office in an unexpected reaction can be treated quickly. Injections should be given only to those with experience in the treatment of allergic emergencies. Patients should never give a helping allergy!
What to do when a shot is missed allergy
For all practical purposes, nothing. A global response to desensitization depends on the cumulative dose of allergen over a long period, not a single dose. Therefore, if a blow from time to time is lost, the entire program will not be affected. Everyone will miss a shot from time to time due to illness, vacation, or unexpected, and it is expected. On the other hand, we must be very diligent to receive your injections on time whenever possible.
Is it really necessary to wait 20, 30 minutes after a sudden allergy?
Yes! As mentioned above, allergic reactions to the injections are very rare but occur. Most of these reactions is evident within 20 to 30 minutes. Therefore, after receiving your allergy shot, you should expect in the allergist office from 20 to 30 minutes.
Drugs that interfere with immunotherapy
Some medications used to treat high blood pressure, heart rhythm disturbances and headache can be treated by an allergic reaction more difficult. These drugs, called beta-blockers are widely used. Some beta-blockers are commonly prescribed:
* Acebutolol hydrochloride (Sectral).
* Atenolol (Tenormin).
* Betaxolol (Kerlone).
* Bisoprolol (Zebeta).
* Carteolol (Ocupress).
* Carvedilol (Coreg).
* Labetalol (Trandate Normodyne or similar).
* Metoprolol (lopressor, Toprol XL o).
* Nadolol (Corgard).
* Penbutolol sulfate (Levatol).
* Pindolol (wiper).
* Propranolol (Inderal).
* Sotalol (Beta Pace AF).
* Timolol (Blocadren).
If you use any of these medications, provide this information to your allergist or allergy nurse, and we hope an alternative medicine can be found with immune therapy program can continue.
The immunotherapy during pregnancy
Pregnancy is not an indication for cons-injections against allergies. However, the start of desensitization are not recommended during pregnancy. For those who become pregnant after the start of immunotherapy, studies show that anti-allergy injections are sure to continue, but the dose must be kept constant.
Is it useful to receive immunotherapy?
In most cases the answer is definitely yes. Allergy symptoms can range from mild to severe and can cause chronic symptoms in the eyes, ears, nose, throat, lungs and skin, resulting in a quality of life in danger. In addition, allergies are a major cause of absenteeism from school and work, and general loss of productivity. If it is determined that desensitization may play an important role in allergy or a complete program of your child stick to it. You will probably be quite satisfied with the results.
