If you’ve tried antihistamines, nasal sprays, and lifestyle changes but still feel like allergies run your calendar, not the other way around, immunotherapy is usually the next conversation.
This is the point where many patients ask the same question: What are my actual allergy immunotherapy options, and how different are they really?
Let’s walk through the main approaches, how they work, and the practical pros and cons so you can make a more informed decision before talking with your allergist.
What allergy immunotherapy is actually doing
Unlike medications that manage symptoms, immunotherapy works at the immune system level.
The goal is to gradually retrain your immune system so it reacts less aggressively to specific allergens over time. That can mean fewer symptoms, less reliance on daily medication, and longer-lasting relief even after treatment ends.
Most options follow the same basic principle. They differ in how the allergens are delivered and what that experience looks like for the patient.
Allergy shots (subcutaneous immunotherapy)
Allergy shots are the most established and widely studied form of immunotherapy.
How shots work
- Small amounts of allergens are injected into the body, usually in the back of the arm
- Doses increase gradually during a build-up phase
- Maintenance doses follow once tolerance improves
This process typically spans several years, but the structure is predictable and well understood.
Pros of allergy shots
- Strong long-term evidence supporting effectiveness
- Customizable based on your specific allergy profile
- Often covered by insurance plans
- Effective for multiple allergens at once
Cons of allergy shots
- Requires regular office visits
- Time commitment can be challenging at first
- Small risk of allergic reactions, which is why injections are supervised
For patients with moderate to severe allergies or multiple triggers, shots remain the gold standard.
Allergy drops (sublingual immunotherapy)
Allergy drops are another option many patients have heard about, even if they are less familiar with the details.
How drops work
- Liquid allergen extracts are placed under the tongue
- Taken on a consistent schedule, usually at home
- Designed to build tolerance over time, similar to shots
Pros of allergy drops
- No injections
- Can be taken at home after guidance from your allergist
- Often appealing to patients who are needle-averse
Cons of allergy drops
- Not as extensively studied as shots in the U.S.
- Insurance coverage can be more limited
- Typically targets fewer allergens at a time
While Colorado Allergy & Asthma Centers does offer drops, they are not always the best fit for every patient. They are often discussed during consultations so patients understand where they may or may not make sense in their treatment plan.
Emerging and evolving immunotherapy treatments
You may also hear about newer or developing approaches to allergy treatment. These often come up online or in patient forums.
Examples include:
- Modified dosing schedules aimed at faster build-up
- Research into new delivery methods
- Adjunct therapies designed to improve tolerance or safety
While some of these are promising, many are still being studied or are not yet standard practice. It is important to separate what is available today from what is still under investigation.
A board-certified allergist can help you understand what is proven, what is optional, and what is better left on the horizon.
Comparing allergy immunotherapy options at a glance
When patients compare allergy immunotherapy options, it usually comes down to a few practical questions:
- How severe are my symptoms?
- How many allergens am I reacting to?
- How much structure versus flexibility do I want?
- What does my insurance support?
There is no universal “best” option. The best choice is the one that balances effectiveness, safety, and your ability to stick with the plan long term.
How to choose the right option for you
This is not a decision to make based on convenience alone.
An allergist will look at:
- Your allergy testing results
- Symptom severity and seasonality
- Asthma or other related conditions
- Your schedule and treatment preferences
From there, you can have a clear conversation about which approach aligns best with your goals and lifestyle.
The takeaway
Immunotherapy is about changing the trajectory of your allergies, not just managing flare-ups.
Understanding your allergy immunotherapy options, including shots, drops, and emerging treatments, puts you in a stronger position to choose a path that actually fits your life.
If you are considering immunotherapy, the next step is a personalized evaluation to determine which approach makes the most sense for you and why. Contact us or visit one of our many locations in Colorado to get relief from your allergy symptoms.
