Allergen Immunotherapy

Purpose

Your individualized course of allergy shots (immunotherapy) is designed to decrease your allergic sensitivities. The vast majority of allergic patients (80-90%) will experience substantial reductions in their symptoms over time (months to years). Many also reduce or eliminate the need for other medications. Together with avoidance of offending allergens and medication allergy shots represent one of the recommended treatments for allergic rhinitis, allergic conjunctivitis, atopic dermatitis and asthma. Allergy shots are not useful for food/drug allergies or non-allergic conditions like infections.

Treatment Duration

The length of a treatment course varies on a case by case basis but in general a course requires 3 to 5 years of maintenance treatment for completion. Initially there is a build-up phase where the injections are given more frequently but as the High Dose, or maintenance dose, is reached the frequency of injections may be adjusted. The total duration of therapy can vary considerably from patient to patient. During your treatment you will be re-evaluated frequently by your physician. These visits will occur at least annually.

Schedule of Administration

Your series of injections begins at a low dose selected by your physician based on your skin test results and history. Over time the shots build gradually until you reach your High Dose. This High Dose is called the maintenance dose and you will stay on it for the duration of your treatment course unless it is changed by your physician. Maintenance therapy can be continued if you are pregnant BUT notify your OAAC physician when you become pregnant.

The build-up phase of the allergy shots can occur in different formats. Your physician will help you decide which is right for you. Most common is the weekly building schedule. Various accelerated schedules include: 2 or 3 time a week shots, clusters of several shots given on the same day and finally RUSH therapy where many injections are given on one day and then weekly shots follow until you are at your High Dose. RUSH therapy is associated with significantly more side effects (see below) and is not for every patient. However, it does bring you to the High Dose level in a month rather than slowly over many months. This is an advantage for some patients.

Safety

All allergy shots carry some risks for severe anaphylactic reactions. Therefore the injections need to be administered in a medical facility under medical supervision on a regular basis. Weekly or twice weekly shots from our clinic carry a risk of anaphylaxis of 0.015 to 0.02% of injections compared to nationally published risks of 0.1 to 0.3% of injections. RUSH therapy carries a nationally published risk of almost 40% of shots whereas our RUSH risk is closer to 10% of injections. This marked increase in risk however makes RUSH therapy unacceptable for many patients.

Why Should You Visit an Allergist

Is it a cold, the flu, or persistent seasonal allergies made worse by Oklahoma weather? Do your rashes seem to appear at a certain time of year or after you eat specific foods? A board-certified allergist can help you untangle these mysteries and get you to a place where you feel. In this article, you will learn the following points:

  • What an allergist does and what they test for
  • When you may consider getting an allergy test

When You Go to an Allergist, What Do They Do?

Allergists perform testing to determine what their patients are allergic to. They prescribe various treatments, including antihistamines, inhalers, creams, and allergen immunotherapy, to help their patients feel better. If you're considering visiting an allergist, think about your symptoms and when they appear. For example, you may know that you have a severe cat allergy if you always sneeze, cough, or break out into hives when you visit your best friend, who has five feline companions in the house. A food allergy may be equally obvious and even life-threatening due to its severity.

On the other hand, you may have no clue what you're allergic to. This is where a qualified allergist can help you by performing standardized, research-backed allergy testing to determine the cause of your suffering.

What Do Allergists Usually Test For?

Your allergist at Oklahoma Allergy & Asthma Clinic will first talk to you, discuss your medical history and review your symptoms. If you experience hives or anaphylactic shock (a serious, life-threatening reaction) after eating a food, your doctor may run a series of tests to determine the offending food. If your symptoms involve itchy eyes, sneezing, a sore throat, or a cough, your allergist will likely perform a skin test for environmental allergies such as different types of pollen, animal dander, dust, and mold.

If you have eczema or other skin symptoms related to allergies, the allergist may review the products you use daily and perform patch testing for contact dermatitis caused by lotions, shampoos, or fragrances.

When Should You Get an Allergy Test?

When to see an allergist depends on the severity and frequency of your symptoms. Sometimes, it's enough for patients with milder symptoms to simply take an over-the-counter antihistamine for the duration of allergy season. If your symptoms are frequent and bothersome, you've had a severe reaction to food, or you have symptoms of asthma, including shortness of breath or frequent coughing, it's time to visit an allergist for treatment. Allergies typically don't get better over time, but a personalized treatment regimen can help a great deal.

Is It Expensive To See an Allergist?

Your insurance may cover part or all your consultation and testing. Don't let financial concerns stop you from seeing an allergist — especially if you or your child is suffering from chronic or unexplainable symptoms. Treating allergies can drastically improve a person's quality of life.
