Allergy Shots

What Are Allergy Shots?

Immunotherapy allergy shots help reduce allergic reactions by introducing small amounts of allergens (substances that trigger allergies) into the body over time. This treatment makes the immune system less sensitive to specific allergens, ultimately reducing allergic symptoms.


At Premier Allergy of Texas, we specialize in expert allergy management via allergy shots. Our experienced specialists provide expert care and stay updated on the latest evidence-based treatments that work for your health and lifestyle.

Understanding the Phases

Subcutaneous immunotherapy (SCIT) consists of two main phases: build-up and maintenance. 


In the build-up phase, your allergist administers increasing doses of allergens over several months until your body's immune system builds up a tolerance to them. During this phase, you will receive shots once or twice a week.


Once you reach the target dose, you will enter the maintenance phase. The intervals between shots will gradually increase from two to four weeks and eventually to monthly or even longer intervals. Depending on the severity of your allergies and response to treatment, the maintenance phase could last several years.

Managing Allergy Shots

Throughout the treatment, your allergist will monitor you closely for adverse reactions. If you experience itching, swelling, or difficulty breathing, inform your allergist immediately. These reactions may indicate the need to adjust your dose or opt for other treatments. 


Note that this intervention doesn't offer a quick fix: allergy shots require long-term commitment and effort. However, with patience and consistency, they can lead to significant and lasting relief, giving you the freedom to enjoy life with fewer allergy interruptions.

Conditions Treated

Allergy shots effectively treat seasonal allergies, dust mites, pet dander, mold, allergic asthma, and insect sting allergies. Our board-certified allergist will determine the specific allergens causing your reactions and customize your allergy treatment plan accordingly.

Safety and Side Effects

Allergy shots may cause some side effects, including:


  • Redness
  • Swelling
  • Itching 


These symptoms usually disappear within a few hours. In rare cases, allergy shots can cause more severe reactions, such as anaphylaxis. However, the risk of anaphylaxis is low, and our allergist will monitor you closely during the treatment to ensure your safety.

  • Where can I get allergy shots?

    Allergists or immunologists usually administer allergy shots in a clinic. If needed, your primary care physician can help connect you with an allergist to start this treatment.

  • How long does the effect of allergy shots last?

    Allergy shots can remain effective for several years, but it's important to keep up with maintenance shots (as prescribed).

  • What different types of allergy shots are available?

    Allergy injections fall into various categories:

    • Subcutaneous immunotherapy (SCIT) involves a qualified healthcare professional, such as an allergist, immunologist, or trained nurse, administering injections just beneath the skin's surface.
    • Cluster immunotherapy is a variation of SCIT that requires multiple injections daily over several hours.  
    • Rush immunotherapy is an accelerated form of SCIT. In this method, your specialist administers numerous doses of allergen extracts, gradually increasing the dosage to reach the maintenance level more quickly.
