Does Immunotherapy Work in Treating Allergic Rhinitis? Here’s What You Need to Know
Allergic rhinitis affects millions worldwide, manifesting in symptoms like sneezing, a runny or stuffy nose, itching, and sometimes even red, watery eyes.
These symptoms arise from the body’s immune response to allergens such as pollen, pollution (haze), dust mites, or pet dander. Though rare, it can also be caused by certain food allergies.
Amidst various treatment options, immunotherapy emerges as a unique approach, aiming to alleviate symptoms and fundamentally modify the immune system’s response to allergens. Let’s explore how this treatment works and whether it’s the right choice for you.
Key Takeaways
- Immunotherapy gradually reduces sensitivity to specific allergens and may lessen symptoms over time.
- Unlike antihistamines and nasal corticosteroids that control symptoms, immunotherapy can modify how the immune system responds to allergens.
- Benefits may continue after treatment ends, although individual responses vary.
- Immunotherapy risks include injection-site reactions, oral itching and, rarely, a severe allergic reaction.
- Common allergens include pollen, dust mites, mould and pet dander; haze and pollution may worsen symptoms.
Understanding Allergic Rhinitis
Allergic rhinitis happens when one’s immune system identifies an airborne substance as harmful, triggering symptoms that can severely disrupt daily activities and potentially reduce one’s quality of life.
Common triggers include pollen, dust mites, pet dander, and occasionally, food allergies or pollutants like smoke or haze. Understanding these triggers and the severe implications of long-term allergic rhinitis is the first step towards effective management and treatment.
What is Immunotherapy?
Immunotherapy represents a paradigm shift in treating allergic rhinitis. Available primarily in two forms—subcutaneous immunotherapy or SCIT (injections under the skin) and sublingual immunotherapy or SLIT (tablets or drops under the tongue). The objective of immunotherapy is to gradually desensitise the body to specific allergens.
The ultimate goal? To reduce and potentially eliminate allergic reactions. Unlike conventional treatments such as antihistamines and nasal corticosteroids that temporarily relieve symptoms, immunotherapy targets the underlying immune response, offering a more enduring solution.
There are two ways to administer immunotherapy:
- Oral: This method involves taking pills or capsules that are ingested. For allergies, tiny amounts of the allergen can be administered orally to raise the threshold that causes a reaction. The initial dose is typically given in a doctor’s office, while follow-up doses can be taken at home. This offers a painless approach to immunotherapy.
- Subcutaneous: Immunotherapy can also be administered through injections under the skin.
Studies provide evidence supporting immunotherapy’s efficacy in treating asthma and allergic rhinitis. Data also suggests that both subcutaneous and sublingual immunotherapy have clinical benefits and should be continued for at least three years.

Benefits of Immunotherapy
The benefits of immunotherapy extend beyond mere symptom management. Patients often experience a reduction in symptoms that lasts even after treatment has ceased, pointing to a potential long-term effect.
This lasting impact starkly contrasts with the temporary relief offered by traditional medications, making immunotherapy a compelling choice for long-term health improvement.
Risks and Considerations
However, immunotherapy is not without its risks and side effects, which include irritation at the injection site, oral itching, and, rarely, severe allergic reactions. Therefore, it’s crucial to discuss these risks with a healthcare provider.
Not all patients are candidates for immunotherapy; suitability is determined based on one’s medical history, the severity of symptoms, and the specific allergens causing reactions. Here are some key considerations:
Allergen Specificity: Ideal candidates have clear, well-defined allergen triggers, such as pollen, dust mites, or pet dander, as confirmed by allergy tests.
Symptom Severity and Duration: Those with moderate to severe symptoms that persist for several months a year may benefit more from immunotherapy.
Treatment History: Best suited for individuals whose symptoms are not adequately controlled by standard medications like antihistamines or nasal corticosteroids.
Health Conditions: Candidates should not have severe asthma or cardiovascular issues, as these conditions can complicate immunotherapy treatment.
Moreover, patients need to commit to a long-term treatment plan requiring regular doctor visits. Schedule a consultation with Dr Dennis Chua if you have concerns about immunotherapy.
How to Get Started with Immunotherapy
If you’re considering immunotherapy, start by consulting with an ENT specialist or allergist. These experts can offer a tailored treatment plan based on a thorough diagnosis, typically involving skin or blood tests to identify specific allergens. The treatment process can span several years, with regular updates and adjustments needed based on your response to the therapy.
Immunotherapy holds promise as a transformative approach to treating allergic rhinitis, with the potential to improve the patient’s quality of life by reducing or even eliminating symptoms. While it comes with certain risks, the benefits for suitable candidates can be life-changing.
