What Are Allergy Shots?

Allergy shots, also called subcutaneous immunotherapy, are a form of long-term allergy treatment designed to reduce your immune system’s sensitivity to specific allergens. During treatment, small, gradually increasing doses of an allergen are injected under the skin. Over time, this process helps your immune system build tolerance, which may reduce the frequency and severity of allergic reactions.

Allergy shots are commonly recommended for patients whose symptoms are not well controlled through medications such as antihistamines or decongestants alone. They may help address a wide range of triggers, including pollen, dust mites, pet dander, mold, and insect venom. Allergy testing is completed first to identify your specific allergens and guide a personalized treatment plan.

Allergy Testing: The First Step Toward Relief

Before allergy shots can begin, thorough allergy testing is essential. Testing helps our ENT specialists identify which specific allergens are triggering your symptoms. Common symptoms that prompt allergy testing include sneezing, runny nose, itchy eyes, hives, swelling, and difficulty breathing in patients who also have asthma.

Allergy testing typically involves a skin prick test or intradermal test, depending on your history and the allergens being evaluated. If you are unsure whether your symptoms are related to allergies or another condition, our providers can help clarify the diagnosis.

Who Is a Good Candidate for Allergy Shots?

Allergy shots may be considered for adults and children who experience moderate to severe allergy symptoms that interfere with daily life. Candidates often include those who:

  • Have not responded adequately to medicines such as antihistamines or decongestants
  • Experience allergic reactions to multiple allergens throughout the year
  • Suffer from allergic rhinitis, asthma triggered by allergens, or food allergy-related conditions discussed during consultation
  • Prefer a long-term treatment approach rather than ongoing daily medications
  • Want to reduce their reliance on allergy medicines over time
  • Are committed to completing the full course of immunotherapy, which typically spans three to five years

Candidacy is always determined on an individual basis. Your provider will review your medical history, allergy testing results, and symptoms before recommending allergy shots or an alternative treatment approach.

Allergy Drops and Sublingual Immunotherapy

For patients who are not candidates for injections or prefer an alternative, allergy drops may be an option worth discussing. Sublingual immunotherapy, or SLIT, delivers allergen extracts in drop form placed under the tongue. Like allergy shots, sublingual immunotherapy works by gradually exposing the immune system to small allergen doses to build tolerance.

Allergy drops are often considered for children, patients with needle sensitivity, or those who find frequent office visits difficult to commit to. SLIT drops are typically administered at home, though treatment still requires regular follow-up appointments with your provider to monitor progress. Our specialists will help you understand whether allergy drops or allergy shots are better suited to your individual needs based on your testing results and symptom profile.

What to Expect During Allergy Shot Treatment

Allergy shot treatment is delivered in two phases. During the build-up phase, injections are given one to two times per week, with the allergen dose increasing gradually over several months. Once a maintenance dose is reached, the frequency of office visits decreases to once or twice per month.

Most patients tolerate allergy shots well. Common reactions at the injection site may include mild redness or swelling, which typically resolve quickly. As with any medical treatment, more significant allergic reactions can occur, which is why injections are administered in a clinical setting where your provider can respond appropriately. Individual results vary, and the full benefits of immunotherapy are generally reported after one to two years of consistent treatment.

Frequently Asked Questions About Allergy Shots

How long does it take for allergy shots to work?

Most patients begin to notice some improvement in allergy symptoms within the first year of treatment, though full benefits are typically reported after one to two years of consistent immunotherapy. Individual results vary based on the allergens being treated and how well your immune system responds to the injections.

How often do I need to come in for allergy shots?

During the build-up phase, allergy shots are typically administered one to two times per week. Once you reach the maintenance dose, office visits are generally required once or twice per month. Your provider will outline a specific schedule based on your treatment plan.

Are allergy shots safe for children?

Allergy shots are commonly recommended for children and adults. Candidacy for children depends on age, symptom severity, and the ability to commit to a regular treatment schedule. Our specialists will evaluate each child individually and discuss whether allergy shots or sublingual immunotherapy may be more appropriate.

What is the difference between allergy shots and allergy drops?

Allergy shots are injected under the skin during office visits, while allergy drops, or sublingual immunotherapy, are placed under the tongue and can often be taken at home. Both are forms of allergen immunotherapy, but they differ in delivery method, administration frequency, and patient suitability. Your provider will discuss which option is recommended for your specific situation.

Does insurance cover allergy shots?

Many insurance plans provide some coverage for allergy testing and allergy shots, though coverage varies depending on your plan and provider. We recommend contacting your insurance carrier directly to understand your benefits. Our team can also help address questions about cost and coverage during your consultation.

What allergens can allergy shots treat?

Allergy shots may be used to address a range of allergens, including pollen, dust mites, mold, pet dander, and insect venom. Allergy testing is conducted first to identify your specific triggers, and your immunotherapy formulation is customized accordingly. Food allergy treatment through allergy shots is not standard and would be discussed separately with your allergist.

What should I do if I have a reaction after an allergy shot?

Mild reactions such as redness or swelling at the injection site are common and typically resolve on their own. More significant allergic reactions, while less common, can occur, which is why patients are asked to remain at the clinic for a period of observation following each injection. Your care team is prepared to respond to any reactions that may arise.
