Allergy Shots in Phoenix, AZ
Subcutaneous Immunotherapy for Allergies
Allergy shots are a well established form of immunotherapy for allergies used to reduce long term sensitivity to environmental triggers. For patients in Phoenix and across Arizona who struggle with persistent symptoms despite medications, allergy shots offer a structured medical approach designed to retrain the immune system over time.
What Are Allergy Shots?
Allergy shots, also called subcutaneous immunotherapy, involve injecting controlled amounts of allergens just under the skin. These allergens are identified through comprehensive allergy testing performed in our Phoenix clinic.
Each injection contains a carefully measured dose of the substances that trigger your symptoms, such as pollen, dust mites, mold, or pet dander. The goal is not to provoke a reaction, but to gradually train the immune system to become less reactive.
Types of Allergies Treated with Allergy Shots
Allergy shots are primarily used to treat environmental and respiratory allergies. They are not recommended for food allergies. Below are the main categories of allergies that may be treated with allergy shots.
Seasonal and Year-Round Allergies
Allergy shots are effective for both seasonal and year-round environmental allergens. Seasonal allergies triggered by grass, trees, weeds, and ragweed are commonly treated, as are year-round allergies caused by dust mites, which can cause persistent symptoms regardless of the time of year.
Pet Dander and Mold Allergies
For those who react to animals or their environment, allergy shots can provide significant relief. Pet dander allergies, particularly to cats and dogs, respond well to this treatment. Mold allergies, which can be both seasonal and year-round depending on climate and living conditions, are also commonly addressed through allergy shots.
Asthma and Insect Sting Allergies
Allergy shots may also be recommended for more serious allergic conditions. Allergic asthma that is triggered by environmental allergens can be managed and reduced over time with immunotherapy. Additionally, insect sting allergies including reactions to bees and wasps are among the most important conditions to treat with allergy shots, as these reactions can be life-threatening.
Lindsey Forstie, FNP and the Journey That Shaped Her Approach to Allergy Care
Lindsey’s journey into allergy and asthma care began long before her medical training. As a child, she struggled with undiagnosed asthma. Physical activity meant chest tightness, headaches, and falling behind despite her effort. For years, she believed her limitations were personal rather than medical. It was not until a school nurse recognized the signs of asthma and proper treatment began that everything changed. Breathing improved, confidence returned, and the boundaries she had quietly accepted began to disappear.
That experience shaped the direction of her career. Lindsey became a nurse, then a board certified family nurse practitioner specializing in allergy and immunology. She founded Carefree Allergy with a clear mission: no one should have to live within unnecessary limits caused by untreated asthma or uncontrolled allergies.
Lindsey combines evidence based medicine with compassionate, patient first care, helping children and adults move beyond symptom management toward lasting relief and renewed confidence in their health.

Benefits of Allergy Shots
Allergy shots have been used for over a century and remain a trusted option in allergy care. Benefits may include:
Less Severe Symptoms
Reduced severity of seasonal and year round symptoms
Less Medication Dependency
Decreased reliance on daily antihistamines, nasal sprays, and other allergy medications.
Better Asthma Control
Improved management of asthma symptoms when environmental allergens are a known trigger.
Long-Term Immune Change
Gradual modification of the immune system's response rather than temporary symptom suppression.
Lasting Relief
Potential for continued symptom relief even after completing the full course of treatment.
Improved Quality of Life
Greater ability to enjoy outdoor activities, pets, and daily routines with fewer allergy disruptions.
How Do Allergy Shots Work?
Treatment happens in two main stages:
01
Build Up Phase
Injections are given one to two times per week for several months. The allergen dose gradually increases as your body builds tolerance.
02
Maintenance Phase
Once the ideal dose is reached, injections are spaced out, typically every few weeks. Maintenance treatment usually continues for three to five years to reinforce long term immune change.
Because allergy shots carry a small risk of reaction, each injection is administered in a medical setting. Patients remain in the office for approximately 30 minutes after each shot for monitoring.
Allergy Drops: a Modern Alternative for Allergy Shots
Allergy shots have long been recognized as an effective treatment for managing environmental allergies, and for many patients they offer real, lasting benefits. However, we believe that allergy treatment should be accessible and affordable for everyone — not just those who can commit to frequent clinic visits or navigate high out-of-pocket costs.
That’s why at Carefree Allergy, we offer allergy drops instead of allergy shots. Allergy drops work on the same principle of gradually building your immune system’s tolerance to allergens, but they are taken conveniently at home under the tongue rather than requiring regular injections at a clinic. This means fewer appointments, lower costs, and a treatment experience that fits into your life on your own terms.

What Is a Kenalog Injection and Is It Really an Allergy Shot?
Kenalog is a long-acting corticosteroid injection (triamcinolone) that works by suppressing inflammation throughout the entire body. Because it can reduce allergy symptoms for several weeks to months, some patients refer to it as an “allergy shot.” However, Kenalog is not immunotherapy and does not treat the underlying cause of allergies in any way. It simply masks symptoms temporarily, making it more of a short-term band-aid than a real solution.
While Kenalog may offer brief relief, repeated or routine use carries significant risks. Because it is a systemic steroid that affects the whole body, potential side effects include immune system suppression, blood sugar elevation, weight gain, mood changes, bone loss, and hormonal suppression. For this reason, most modern allergy practices have moved away from offering routine steroid injections, as the long-term risks simply outweigh the short-term benefits when safer and more targeted treatments are available.
The key difference between Kenalog and true allergy immunotherapy is that immunotherapy actually retrains the immune system to reduce its sensitivity to allergens over time, addressing the root cause rather than temporarily suppressing symptoms. Today, modern allergy care focuses on treatments that are both effective and safe for long-term use, including personalized allergy testing and treatment plans and sublingual immunotherapy, also known as allergy drops. If you have been receiving Kenalog injections for allergy relief, it may be worth exploring a more lasting and lower-risk approach to care.
Common Questions
What are allergy shots?
Allergy shots are a form of immunotherapy that helps reduce sensitivity to allergens like pollen, dust mites, mold, and pet dander by gradually training the immune system to tolerate them.
How do allergy shots work?
They expose the body to small, controlled amounts of allergens over time, which reduces the immune system’s overreaction and leads to fewer allergy symptoms.
How often are allergy shots given?
Treatment has two phases: build-up phase (typically 1–2 injections per week) and maintenance phase (injections every 2–4 weeks).
How long does treatment last?
Most patients remain on allergy shots for 3–5 years to achieve long-term benefit.
How long does it take to see results?
Some patients notice improvement within a few months, but most see meaningful results after 6–12 months.
Are allergy shots effective?
Allergy shots are widely considered an effective option for reducing allergy symptoms and decreasing reliance on daily medications. That said, at Carefree Allergy we exclusively offer allergy drops, which work on the same proven principles of immunotherapy but with greater convenience, affordability, and accessibility. We believe allergy drops are the smarter, more patient-friendly path to long-term relief — and that is why they are the foundation of everything we do.
Are allergy shots safe?
They are generally safe when administered in a medical setting. There is a small risk of a systemic allergic reaction.
What are the side effects?
Common side effects include redness or swelling at the injection site and mild allergy symptoms. Rare but serious reactions can occur.
Why do I have to wait after my injection?
Patients are required to stay in the office for about 30 minutes after each injection to monitor for potential allergic reactions.
