Allergen Immunotherapy

Important Details about Allergen Immunotherapy

What is allergen immunotherapy?

You can alter how your body responds to allergens, or items you are allergic to, by undergoing allergy immunotherapy. Immunotherapy treats allergies directly, as opposed to other allergy medications that only lessen symptoms. By inhibiting your body’s response to triggers for allergic reactions, allergen immunotherapy helps either avoid or minimize allergies. Years may pass before it works.
When your body’s immune system reacts to something that is often safe, you get an allergic reaction. Over the course of several years, the body is gradually exposed to minuscule quantities of the allergen as part of allergy immunotherapy. Your immune system “switches off” over time, preventing you from reacting to the allergen.

How is allergen immunotherapy given?

Allergen immunotherapy is administered as subcutaneous injections, oral pills, oral sprays, or sublingual drops. Injections: A tiny amount of the allergen is administered using a tiny needle. Usually, these injections don’t hurt. You often require weekly shots at first. Till a constant (maintenance) dose is reached, the dosage is progressively raised over the course of three to six months. After that, you will require monthly injections for a few years.

Sublingual immunotherapy is administered under the tongue and can be administered as tablets, sprays, or drops. After holding the allergen under your tongue for a short while, you swallow it. This kind of immunotherapy is less likely to cause negative effects and can be used at home. This is costlier and less effective than injections for certain types of allergies.

After roughly four to five months, symptoms normally start to get better. You must continue taking the immunotherapy on a regular basis and collaborating closely with your physician during this period. In order to stop the allergies from coming back, the course of treatment should often be continued for three to five years. As directed by your physician, keep taking your allergy and asthma medications during allergen immunotherapy. A clinical immunologist or allergy specialist should always oversee the administration of allergy immunotherapy.

Which allergies can allergen immunotherapy treat?

Allergen immunotherapy may be indicated for the following conditions: eczema (rarely), asthma, hay fever (allergic rhinitis) due to pollen or dust mite allergies, potentially fatal allergies to stinging insects like bees, wasps, and jack jumper ants, hay fever (allergic rhinitis) when symptoms are severe and medication isn’t controlling them, Although research is ongoing, allergen immunotherapy is not currently utilized in Australia to treat food allergies due to poor evidence of its effectiveness.
Allergen immunotherapy can be used on both adults and children, though it can be challenging to get very young children to participate. Additionally, those who have certain medical issues, such as heart disease, should not have the treatment.
