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.

Surviving the Heat with Allergies and Asthma

Even though we’ve had a short reprieve from the summer heat, hot temperatures are on the way back. If you have allergies, scorching summer heat intensifies the release of allergens. Pollen, mold spores and dust mites have been wreaking havoc on those who battling allergies and asthma.

If you are following the Oklahoma Allergy & Asthma Clinic pollen and mold count, the readings have had days of high grass pollen and mold. High humidity has created an ideal environment for mold and increased exposure to mold spores. Rain has led to the warm season grasses to flourish and grow. Then, weekend warriors and lawn services continue to mow lawns and outdoor areas. These high-count days bring on respiratory issues for those with pollen and mold allergies.

For those with asthma, extreme heat might even affect you more. Breathing in hot and/or humid air can cause airways to narrow and tighten. Humidity can cause common allergens such as mold and dust mites to thrive which can aggravate allergic asthma.

Not drinking enough? Dehydration and an electrolyte imbalance secondary to overheating can worsen asthma symptoms. Oklahoma City has already had several air quality alerts which means air pollution is worse and not good for those with breathing and lung issues like asthma. Air particles irritate sensitive airways.

It’s very important to manage exposure to heat, humidity and air pollution to reduce asthma and allergy symptoms during these summer heat spells. Try to stay inside during peak pollen times (early mornings and evenings). Keep windows and doors closed to keep grass pollen outside. Wear a mask if you have to mow your lawn. Use an air purifier to remove up to 99.97 percent of allergens including dust mites in the air.

Air conditioning can also help reduce allergy symptoms in the hot summer months. It filters and circulates air and removes the airborne allergens such as pollen, mold spores and dust mites from indoor spaces. Be sure to regularly maintain your air conditioner by regularly cleaning the unit and replacing the filters.

If you are struggling with your asthma and/or allergens in this heat, you are not alone. Your OAAC providers are here to support you in every step of your journey. The good news is…fall is on the way. The bad news is…it’s allergy season every day in Oklahoma.
