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.

May is Allergy and Asthma Awareness Month

Breathe Better with Asthma, Wherever You Are

If you have asthma, you know that symptoms can come on quickly, then worsen. The things that make them do that are called triggers. An important part of managing asthma is knowing what your triggers are — at home, work, school, or while you’re outdoors. A healthcare provider can help you figure that out, then you can take steps to avoid those triggers and breathe easier.

At home

Because asthma is usually due to allergies, triggers are often allergens, or things that cause allergic reactions. Allergens such as pet dander, dust mites, pests, and smoke can make asthma symptoms worse in some people, and for others, even trigger an asthma attack. The National Heart, Lung, and Blood Institute (NHLBI) suggests that it may be helpful to combine a few different strategies to help reduce exposure to triggers. People sensitive to dust can clean with a high-efficiency particulate air (HEPA) filtration vacuum and use mattress and pillow covers that prevent exposure to dust mites. If you’re sensitive to pests like cockroaches and rodents, consider integrated pest management, which involves removing and controlling pests through methods such as traps or poison. Avoiding tobacco smoke, including secondhand smoke, can be especially helpful for some people with asthma.

At school

Asthma is one of the leading reasons children miss school. At school, kids may be exposed to dust mites, pests, and mold, which may be asthma triggers for some children. Because children spend lots of time at school, it can be helpful for teachers, school nurses, or coaches to know what to do if your child’s symptoms flare up. Team up with a healthcare provider to develop an asthma action plan and share it with trusted adults at your child’s school.

At work

The workplace can have hundreds of potential triggers, like chlorine-based cleaning products, bleaches, hair dyes, and metal dust. Repeated exposures in the workplace can also lead to new triggers. Report new or worsening symptoms that occur at work to your healthcare provider and your workplace supervisor.

Outdoors

Everyday weather like cold, dry air can set off breathing problems. Air pollution can affect asthma, too. It may be helpful to avoid some of the worst pollution by adjusting when and where you exercise. Try to avoid exercising near busy roads or industrial areas. Visit airnow.gov to check your local air quality so you can plan to avoid outdoor activities when pollution is highest.

Managing your triggers is just one part of keeping your asthma under control. Work with a healthcare provider to develop an asthma treatment plan that includes taking medicines as prescribed and keeping track of your symptoms and where you are when they occur. That way, you can know what’s making your asthma worse or better.
