What Is Allergen Immunotherapy?
Allergen immunotherapy is a long-term treatment that gradually reduces a person’s sensitivity to specific allergens. It works by exposing the immune system to carefully controlled amounts of an allergen over time, helping the body become less reactive. Immunotherapy is commonly given as allergy shots or sublingual tablets placed under the tongue.
This treatment may reduce allergy symptoms, decrease the need for medications, and improve quality of life for people with certain allergies.
Why Allergen Immunotherapy Matters
Unlike medications that temporarily relieve symptoms, immunotherapy addresses the underlying allergic response. It may provide long-lasting symptom improvement and reduce the severity of future allergic reactions for appropriately selected individuals.
Conditions Commonly Treated with Immunotherapy
- Seasonal allergies
- Pollen allergies
- Dust mite allergies
- Mold allergies
- Pet dander allergies
- Certain insect sting allergies
How Allergen Immunotherapy Works
- Begins with small doses of the allergen
- Doses gradually increase over time
- Helps the immune system become less sensitive
- Reduces allergy symptoms
- May decrease reliance on allergy medications
- Requires regular treatment over months or years
How Home Care Can Help
Home care professionals encourage individuals to follow their allergy treatment plan, attend scheduled appointments, monitor for changes in symptoms, support medication adherence, and educate families about recognizing allergic reactions and avoiding known triggers.
Home Care Tip
Continue avoiding your allergy triggers even while receiving immunotherapy, unless your healthcare provider advises otherwise. Improvement often occurs gradually over time.
Frequently Asked Questions About Allergen Immunotherapy
Does immunotherapy cure allergies?
It does not cure allergies, but it can significantly reduce symptoms and improve the immune system’s tolerance to certain allergens.
How long does allergy immunotherapy take?
Treatment often continues for three to five years, although the duration varies depending on the individual and the allergens being treated.
Who is a good candidate for immunotherapy?
People with persistent allergies that are not adequately controlled with allergen avoidance and medications may benefit. A healthcare provider or allergist can determine whether immunotherapy is appropriate.
When to Contact Your Healthcare Provider
Contact your healthcare provider if you experience worsening allergy symptoms, side effects after immunotherapy, or signs of a severe allergic reaction following treatment.
