What is Immunotherapy for allergies?

If your child suffers from allergies, you may have heard of immunotherapy as a treatment option. But what exactly is it, and how does it work?

Allergy immunotherapy is a long-term treatment that aims to reduce sensitivity to allergens — the substances that trigger allergic reactions. Instead of simply managing symptoms with medications, immunotherapy addresses the underlying cause of allergies. It can be particularly helpful for children with allergic rhinitis (hay fever), dust mite allergy, animal dander allergies, insect sting allergies and food allergies. It may also benefit those with mild asthma related to allergies.

How does it work?

Immunotherapy involves giving small, controlled doses of the allergen to your child over time. These doses help the immune system become less reactive to the substance, effectively building up a tolerance. This can lead to a significant reduction in symptoms — and in some cases, long-lasting relief even after treatment ends.

There are two main types:

• Subcutaneous Immunotherapy (SCIT) – Often referred to as "allergy shots," this involves regular injections given in a clinic, usually over several years.

• Sublingual Immunotherapy (SLIT) – A needle-free option, this involves placing drops or tablets under the tongue at home, typically on a daily basis.

  
  

Is it safe?

Yes, when overseen by a qualified allergy specialist, immunotherapy is generally safe and well-tolerated, especially for children. The treatment starts with a careful assessment and allergy testing to determine exactly which allergens are involved. Side effects are usually mild and may include itching or swelling at the site of administration. Rarely, more serious allergic reactions can occur, which is why early treatment is often done under medical supervision.

Who is it for?

Immunotherapy isn’t suitable for everyone, but it can be life-changing for many children who don’t respond well to other treatments or whose allergies significantly affect their quality of life. Your child’s allergy specialist will help you decide if this is the right path, based on their symptoms, age, and overall health.

Long-term benefits

The biggest advantage of immunotherapy is its potential to change the course of allergic disease. It can prevent the development of new allergies and may even reduce the risk of asthma in children with allergic rhinitis. For families seeking a proactive, long-lasting solution, immunotherapy can be a powerful option.
