Other Treatments for Asthma
by Michelle Badash, MS
Immunotherapy is an asthma treatment consideration for those whose asthma is exacerbated by allergens (like animal dander), rather than other triggers like viral respiratory infections. It may also be useful for people with nasal symptoms (such as sneezing, stuffy nose).
It is often recommended for people who have developed severe side effects from medication, or when symptoms do not respond well to medication. Immunotherapy may also be helpful for people who have frequent, unavoidable exposure to allergens.
Immunotherapy increases your resistance to allergens and reduces the need for medications. Initially, you will be given shots of weakened solutions of purified allergen extracts 1-2 times per week. As you continue with the shots, the doses will be made progressively stronger. In approximately 3-6 months, your doses will be at the most concentrated, or maintenance, level.
When your injections are at maintenance level, the frequency of injections will be reduced to every 2-4 weeks. Your immune response will be monitored periodically by skin testing. Treatment will continue for about 3-5 years until your allergic response has been significantly reduced or eliminated.
Sublingual immunotherapy may also be used. This type of treatment involves putting the allergic substances under the tongue, rather than using allergy shots.
Immunotherapy is a treatment program that may take 3-5 years to complete. If you are considering this form of treatment, you will need to receive these injections or treatments on a regular schedule. If you miss one or more treatments, there is a risk that your allergen immunity will be compromised, and you may need to begin the process again.
On occasion, some people experience a localized reaction to the shot. This may include itching, redness, or a small swelling in the injection area. These symptoms usually disappear within 1-2 hours.
In very rare instances, a systemic reaction may occur. This might produce symptoms such as sneezing, itching of the eyes, throat, hands, feet, or asthma. This type of reaction usually occurs within 20 minutes of the shot. Your doctor will have you wait at least 20 minutes after receiving an injection to assure that there is no reaction.
Who Should NOT Undergo Immunotherapy
Immunotherapy is not recommended for people who are taking beta-blocker medications. Beta-blocker medications may be prescribed for people who have high blood pressure, heart rhythm problems, or other conditions.
It has not been conclusively determined whether starting immunotherapy is safe during pregnancy. However, it is usually considered safe to continue immunotherapy maintenance treatments during pregnancy as long as it’s approved by your doctor. Immunotherapy is also not recommended for people with weakened immune systems.
