What Are Allergy Shots (Allergen Immunotherapy)?

Allergy shots, also called allergen immunotherapy, are a medical treatment that helps your body become less sensitive to things that trigger allergic reactions. Instead of just treating allergy symptoms with medicines, allergy shots train your immune system so it reacts less strongly to allergens like pollen, dust mites, pet dander, mold, or insect stings. The shots contain very small amounts of the substance you are allergic to. Over time, these doses slowly increase so your body learns not to overreact when it meets the allergen in daily life.

This treatment is especially used when allergy symptoms are strong, do not improve with medicines, or when people want long-term relief. Allergy shots are given over many months and sometimes continue for several years to help give long-lasting benefits.

Purpose & Benefits of Allergy Shots

● Helps reduce allergy symptoms over time

● Trains the immune system to react less to allergens

● Can decrease the need for daily allergy medicines

● May reduce asthma symptoms linked to allergies

● It can give long-term relief, sometimes even after stopping treatment

Who May Need Allergy Shots?

● People with allergic rhinitis (hay fever)

● People with allergic asthma triggered by allergens

● Individuals with year-round symptoms not well controlled with medicines

● Patients with insect sting allergies

● People who want long-term allergy relief and fewer medicines

Types of Allergy Immunotherapy

1. Subcutaneous Immunotherapy (Allergy Shots)

This is the standard allergy shot treatment. A tiny amount of the allergen extract is injected under the skin of the upper arm. Over time, the dose is increased to help the body become tolerant.

2. Cluster or Rush Immunotherapy (Special Schedules)

In some clinics, special schedules like clusters or rush immunotherapy may be used. These give multiple injections in one visit to reach higher doses faster. These methods work faster but may carry more risk and require closer medical supervision.

Allergy Shots Procedure: Step-by-Step

1. Allergy Testing: Before starting, your doctor checks which allergens affect you using skin or blood tests.

2. Build-Up Phase: Shots begin with small doses of allergens. You usually get injections once or twice a week for several months, slowly increasing the dose each time.

3. Maintenance Phase: Once the highest safe dose is reached, shots may be given every 2–4 weeks for several years.

4. Monitoring: After each shot, you stay in the clinic for at least 30 minutes so the healthcare team can watch for reactions.

This schedule helps the immune system slowly adjust and develop tolerance to allergens. Over time, many people notice fewer symptoms and less need for allergy medicines.

Recovery & Aftercare

● Most people go home soon after the shot.

● You may feel mild itching or redness at the injection site.

● Do not do strenuous exercise for a few hours after a shot.

● Keep all scheduled visits; sticking to the plan helps treatment work better.

● If you notice unusual symptoms like trouble breathing, swelling, or dizziness, seek medical help right away.

Risks & Possible Complications

Allergy shots are usually safe when done by trained healthcare professionals. However, possible reactions include:

● Mild reactions, like redness, itchiness, or swelling at the injection site.

● Less common symptoms like sneezing, nasal congestion, or hives.

● Rare but serious reactions (anaphylaxis) that can include throat tightness, wheezing, dizziness, or chest tightness. Because of this, shots are given where doctors can treat reactions immediately.

The risk of serious reactions is low, but it is why you stay in the clinic after each shot.

Allergy Shots vs Other Allergy Treatments

Allergy shots (immunotherapy) train your immune system to tolerate allergens and can give long-term relief that lasts for years after treatment ends.

Other treatments like:

● Antihistamines: help relieve symptoms temporarily

● Nasal sprays: reduce inflammation

● Avoiding allergens lowers exposure

These focus on short-term symptom relief but do not change the immune system’s response to allergens. Allergy shots aim to change how the body reacts to triggers, not just treat symptoms.
