Allergy Immunotherapy in a Nutshell

Allergy immunotherapy is a clinician-prescribed treatment that helps build long-term tolerance to allergens that millions of Americans suffer from.

What you need to know about Sublingual Immunotherapy (Allergy Drops)

The most important thing to know is that allergy drops are a commitment and being diligent is key. Allergy drops are administered under the tongue once daily from home.

How long does it take to see results?

Our providers are optimistic that with consistent daily use, you'll notice a benefit by the end of your first year. By that time, if you haven't seen an improvement in symptoms please let your provider know as there is more we can do to help. We recommend that treatment continues for 3-5 years to achieve long-term results.

What will be included in my formula?

Due to extensive cross-reactivity amongst pollens, you may not see every positive response in your formula, but you can rest assured that every major pollinator will be covered.

Are there any side effects?

Side effects occasionally occur when starting immunotherapy. They can include irritation, numbness, or tingling under the tongue which should wear off over time. If these become troublesome, you can always reach out to us for assistance. Life-threatening allergic reactions are extremely rare and reported anywhere from 1 in 100 million doses to 1 in 1 billion doses. We'll prescribe a generic EpiPen (Epinephrine) to have on hand in case of anaphylaxis. You can choose to pick it up as an extra precaution. If it is expensive please let us know.

What is Immunotherapy?

Allergy immunotherapy is the repeated introduction of medical-grade allergens into the system, building the body’s tolerance and decreasing its reactivity to allergens.

The goal is to provide long-term relief & improve the quality of life by treating the source of allergies, not just the symptoms.

Immunotherapy has been around for over 100 years. More convenient forms of this treatment have started gaining popularity recently, making it accessible to many Americans struggling with allergies.

Common Misconceptions

Myth: “Immunotherapy is not any different than allergy meds.”

Fact: Allergy meds are advertised to provide relief for up to 24 hours, but they only mask the symptoms. Allergy immunotherapy on the other hand, treats the source of allergies for long-term relief.

Another key difference is, immunotherapy utilizes clinical-grade allergen extracts unlike common medications which make use of chemical compounds to temporarily mask symptoms.

Myth: Allergy immunotherapy is considered a “homeopathic treatment”.

Fact: Immunotherapy has been studied rigorously with many clinical trials and peer-reviewed research proving its efficacy.

Myth: “It’s okay to suffer from allergies. I don’t really need a treatment THAT much.”

Fact: Allergies, if untreated, can lead to chronic respiratory health issues such as asthma, or skin disorders like eczema.

It’s also been shown that allergies are the #1 reason people miss work or school. Studies have also shown that students who suffer from allergies receive worse grades than their peers.

Treating the source of allergies can not only improve the quality of life, but help your professional and academic performance.

Is immunotherapy safe?

Allergy immunotherapy is very safe, with mild side effects including redness, itching and swelling.

Severe reactions are extremely rare. Most common form of allergy immunotherapy in the United States is allergy shots, which are administered in person. 

Curex clinicians prescribe a different form of immunotherapy called “sublingual immunotherapy” (SLIT), which is applied under the tongue instead of injections. This form is shown to be even safer, and people with more severe allergies are usually pointed in this direction.

Who is immunotherapy for? Am I a good fit?

A common misconception is that immunotherapy is only for people who experience very severe allergies.

While this treatment is very effective for people suffering from severe reactions, anyone with seasonal, indoor or pet allergies can experience a significant improvement in quality of life as a result of this treatment, along with a lower chance of developing more serious conditions down the road.

Immunotherapy is safe and effective for both adults and kids 5+.

Timeline of Allergy Immunotherapy

First step for allergy immunotherapy to determine your allergies- either using pre-existing allergy test results or an at-home allergy test through Curex.

Once we have your allergy test results, you will meet with a Curex clinician to customize the treatment based on your needs. Your treatment will be shipped to you quarterly.

Months 1-5

During the first several months the goal is to introduce the allergens to your body. Apply the treatment daily under the tongue.

Months 6-12

Most patients start seeing improvements before the end of their first year. In some cases, people start experiencing significant improvement in their symptoms earlier.
