Allergen Immunotherapy

Home > Allergen Immunotherapy

Allergens affect thousands of children across the UK. While some substances are easy to avoid, it can be difficult for you and your little ones to avoid all contact with known and unknown allergens. The good news is that, with immunotherapy, it is possible to train your child’s immune system to suppress its response to allergens such as house dust mites and grass pollens.

If your child is suffering from allergies, immunotherapy provides a preventative treatment that can help you get their allergies under control. That way, your little one can regain their freedom and continue to enjoy life with fewer, if any, symptoms at all. At Midland Health, our paediatric allergy specialist will arrange a private consultation to diagnose, prevent and treat allergies.


What Is Allergen Immunotherapy?

Immunotherapy is designed to prevent allergic reactions by encouraging the immune system to recognise and respond to allergic proteins differently. Treatment involves exposing the patient to very small doses of the allergen that they are allergic to. 

For example, children with pollen allergies make Immunoglobulin (IgE) antibodies to pollen proteins. This treatment teaches the immune system to make different antibodies (IgG4) to the pollen proteins. These new antibodies may compete with the allergic antibodies and redirect the immune system’s response, allowing your child to get relief from their allergy symptoms in the future.

Allergies We Can Treat

It is not uncommon for mild allergies to develop into something more severe as a result of repeated exposure. That is why it is crucial to develop a treatment plan at the earliest opportunity. At our specialist clinic in Birmingham, our skilled professionals can diagnose and treat a range of allergies, desensitisation methods can be successful in treating allergies like:

  • Grass Pollen: Grass pollen is one of the most common allergens and symptoms include sneezing and a runny nose, watery eyes and swelling around the eyes. Immunotherapy involves the repeated administration of small doses of the allergen to reduce the immune system’s sensitivity.
  • House Dust Mites: A dust mite allergy in children can result in common allergy symptoms, including sneezing and coughing. They can even trigger asthma symptoms, such as wheezing and difficulty breathing. But thankfully, immunotherapy can improve tolerance to this substance and reduce symptoms.
  • Birch Pollen: Tree pollen can trigger quite serious allergic reactions, resulting in symptoms such as wheezing and difficulty breathing. Exposure to this allergen can help your child build up a tolerance to tree pollen and provide effective relief.

If your child is struggling with allergy symptoms to these allergens or others, arrange to see our medical experts as soon as possible. With access to cutting-edge tests and equipment, we are well-placed to diagnose and treat your child’s allergies.

Our Allergy Immunotherapy Treatments

At our private clinic in Birmingham, we are able to provide a range of immunotherapy treatments for children with severe allergies. In order to provide your child with effective relief, we are proud to be able to offer:

Oral Immunotherapy

Otherwise known as sublingual immunotherapy, oral immunotherapy provides an alternative way of treating allergies. Treatment involves placing a daily tablet or drops under the tongue for three years. The biggest improvement is seen in the first year and a modest improvement in the second year. Treatment is recommended in the third year to prevent further deterioration and research has shown that it can result in no deterioration over the next five years, although this could be longer.

While treatment can be safely continued at home, we recommend that the first dose is given in a specialist clinic. Our experienced medical professionals can help you and your little one find the right treatment.

Our Paediatric Allergy Specialist

Our paediatric allergy service is led by Dr Tom Dawson, a highly-trained paediatric consultant. Dr Dawson specialises in infections and allergies and has a wealth of experience in immunotherapy treatments. He trained at University College London before treating patients at our Birmingham clinic and has since made a name as an industry expert in his field. 

Chairing the Midlands Paediatric Allergy Group, Dr Dawson is deeply committed to ensuring that outstanding clinical practices are followed for paediatric allergy services across the UK. He is a member of the BRIT committee, a group monitoring nationwide immunotherapy use, as well as the British Society for Allergy and Clinical Immunology Standards Group.

No matter how severe your child’s allergies are, Dr Dawson always takes a compassionate approach to treatment. If your child is suffering from severe allergies, Dr Dawson will be happy to see you for a consultation and will work with you to find a suitable treatment for your child.

How effective is immunotherapy for allergies?

Immunotherapy is highly effective for treating allergies. We advise that treatment is continued for at least three years to decrease the risk of allergies returning.

What are the side effects of allergy immunotherapy?

Generally, local reactions such as oral discomfort and tingling and throat itch reduce over the first few weeks. While systemic reactions, such as hives and nasal congestion and eczema flares are very uncommon, it is wise to consult a medical professional as soon as possible to rule out anything more serious.

How long does allergy immunotherapy last?

Most patients experience lasting effects. In some cases, allergies can return after the treatment has stopped.

How long does it take to work?

Most children will see the biggest improvement in their hay fever symptoms during the first year of treatment. There may be further improvements in the second season, but this is less likely in the third year. However, we advise taking the treatment for the third year to improve long-term outcomes.

What treatments are available?

Some sublingual preparations are licensed and can treat allergies to grass and tree pollen, as well as house dust mites. These would include Grazaxâ, Itulazaxâ and Acarizaxâ. Other unlicensed products are available for the treatment of animals or moulds in the form of drops.

Which allergies does immunotherapy work for?

Immunotherapy works for aeroallergens causing allergies to pollen and house dust mites as well as animals.

Similarly, some people with oral symptoms due to the pollen on foods such as fruits may see an improvement in their symptoms. Those with seasonal asthma symptoms may also see improvements.

It is worth noting that there are some immunotherapy treatments for food allergies but these need to be started in a hospital setting.

Is immunotherapy safe for children?

Yes, immunotherapy is safe for children. Most people will have some side effects at the beginning of treatment with an itchy or tingly tongue and throat. Generally, this only lasts for a few minutes and improves with the duration of treatment. These side effects are usually not reported after 6 weeks.

Treatment may need to be paused for a few days occasionally if these symptoms occur during an illness or after trauma inside the mouth.

Also, keep in mind that there is a very small risk of a severe allergic response, although this is more commonly associated with those who have received subcutaneous (injectable) treatment as opposed to sublingual treatment. Similarly, there are risks for those with severe or uncontrolled asthma and therefore immunotherapy is not recommended for this group. Some immunotherapy products may not be suitable for those with an allergy to fish.

At what age can you start immunotherapy?

Research studies have demonstrated effectiveness in children as young as age 4. However, we recommend our licensed treatments from 6 or 12 years of age depending on the preparation. After all, it may be more difficult to administer treatment in some children under 6.

What is the success rate of immunotherapy in children?

After three years about 15% of those treated will not require any treatment for their hay fever. Most requiring regular treatment with nasal spray and/or antihistamine will need only intermittent treatment. There is also evidence of improvement in asthma symptoms in those with mild asthma or seasonal asthma.

The success rate is dependent on compliance with the treatment. Those who take the treatment every day will see the biggest improvement. Those who do not take their treatment daily will not see as big of an improvement. It is also important for the treatment to be started three months before the pollen season for maximal effectiveness.
