Allergy immunotherapy is a medical treatment designed to reduce or eliminate allergic reactions by desensitizing the body to specific allergens over time. It is often used for people with allergic rhinitis (hay fever), asthma, and certain other allergic conditions. The goal of immunotherapy is to change the way the immune system responds to allergens, making the body less sensitive to them.

How Allergy Immunotherapy Works:

In this treatment, you’re given small amounts of the allergen you’re allergic to, either through shots (called subcutaneous immunotherapy), or tablets or drops (called sublingual immunotherapy). The amount of allergen is slowly increased to help your immune system tolerate it. This helps your body get used to the allergen and stop reacting so strongly to it.

As treatment continues, your immune system makes fewer antibodies (the proteins that cause allergic reactions), which helps reduce symptoms like sneezing, itchy eyes, and stuffy noses.

Types of Allergy Immunotherapy:

  1. Subcutaneous Immunotherapy (SCIT):
    • This involves allergy shots that are given under the skin.
    • At first, you get shots once or twice a week, and over time, the visits become less frequent.
    • Treatment usually lasts about 3 to 5 years.
  2. Sublingual Immunotherapy (SLIT):
    • This involves taking tablets or drops with allergens, placed under your tongue.
    • You take these daily, often at home, and they are used for allergies to pollen, house dust mites, and pets.

Benefits of Allergy Immunotherapy

Allergy immunotherapy, also known as allergy shots or tablets, helps reduce or eliminate allergy symptoms by gradually desensitizing the body to the things that cause allergies. Here are some benefits:

  1. Long-term relief:
    • Allergy shots or tablets can provide long-lasting relief. After finishing treatment, many people find that they need less medicine and have fewer allergy symptoms.
  2. Better control over symptoms:
    • Immunotherapy can help control symptoms like sneezing, itching, runny nose, and itchy eyes. It can also make symptoms less severe when you are exposed to allergens.
  3. Reduces the need for medications:
    • Once you complete allergy immunotherapy, you may not need to take as many antihistamines or other allergy medicines.
  4. Helps prevent asthma:
    • For some people, allergy immunotherapy can help prevent allergies from turning into asthma or help improve symptoms if you already have asthma.
  5. Improves quality of life:
    • By reducing allergy symptoms, immunotherapy can make everyday activities like going outside or playing sports more enjoyable without worrying about constant sneezing or a stuffy nose.
  6. Safe and effective:
    • Allergy immunotherapy is a safe and effective treatment for many people, and it is approved by doctors to help reduce long-term allergy problems.

When is Allergy Immunotherapy Used?

Allergy immunotherapy is used when other treatments, like allergy pills or sprays, don’t work well enough. It’s often used in the following situations:

  1. Severe allergies:
    • If you have strong allergic reactions (like a runny nose, itchy eyes, or sneezing) that don’t go away with regular medicine, allergy immunotherapy can help reduce those symptoms.
  2. If you have multiple allergies:
    • When you are allergic to several things, like pollen, dust, pets, and mold, and it’s hard to keep the symptoms under control, immunotherapy might be a good option to treat them all at once.
  3. If you want to avoid long-term medicine:
    • If you are tired of taking allergy medicine every day, allergy immunotherapy can help you get rid of symptoms for good, so you don’t have to take medicine all the time.
  4. If you aave allergies that lead to asthma:
    • If your allergies cause you to have asthma, allergy immunotherapy can help prevent asthma or reduce asthma symptoms.
  5. If you want long-term relief:
    • If you want long-lasting relief from your allergies without always needing medication, allergy immunotherapy is a good option because it can work for years after treatment.

Possible Side Effects of Allergy Immunotherapy:

Some people may have mild reactions after getting a shot or eye drops. This can include things like redness, swelling, or itching at the spot where they got it. In very rare cases, some people can have a serious allergic reaction called anaphylaxis, especially after getting an allergy shot.
