Allergy Immunotherapy — also known as Desensitization Therapy — is a scientifically proven treatment that helps reduce or eliminate allergic reactions by gradually training the immune system to tolerate allergens that cause symptoms. It is used to treat nasal allergies (allergic rhinitis), asthma, dust mite and pollen allergies, insect venom allergies, and some pet or mold sensitivities.
At Baby Memorial Hospital (BMH), allergy immunotherapy is delivered through personalized treatment plans and is recommended to provide long-term relief from chronic allergic conditions.
Allergy immunotherapy involves administering patients small, controlled doses of the allergen (the substance causing the allergic reaction) via injection or oral drops/tablets, to help the immune system build tolerance over time. Instead of only relieving symptoms (like antihistamines or nasal sprays do), immunotherapy works at the root cause of allergies — helping to retrain the immune system and reduce allergic responses.
Your doctor may recommend immunotherapy if you have:
Immunotherapy is suitable for both adults and children (above 5 years) who suffer from chronic or seasonal allergies.
Immunotherapy works by modifying your immune system’s response to allergens. It happens in two phases:
By the end of treatment, many patients experience lasting improvement even after stopping therapy.
| Type | Method | Common Use |
| Subcutaneous Immunotherapy (SCIT) | Injections under the skin | Dust mites, pollen, molds, insect stings |
| Sublingual Immunotherapy (SLIT) | Drops or tablets placed under the tongue | Dust mites, pollen, pet dander |
At BMH, both SCIT and SLIT are available based on your allergy profile, preferences, and treatment goals.
Yes. Allergy immunotherapy is safe and effective when performed under the supervision of qualified allergists. Mild reactions (like local redness or itching at the injection site) may occur initially but are usually short-lived. Serious reactions (systemic allergies or anaphylaxis) are extremely rare, and all sessions are conducted in a controlled hospital setting for safety.
Allergy immunotherapy is provided by a multidisciplinary team that includes:
Each patient undergoes a thorough allergy testing and evaluation before starting therapy to ensure safety and personalization.
Patients can continue normal daily activities during treatment, as it is typically outpatient-based.
While immunotherapy may not “cure” allergies completely, it provides long-term remission for most patients. Many experience significant improvement that lasts for years after completing therapy — reducing or even eliminating the need for regular medications.
If you suffer from persistent allergies, nasal congestion, or seasonal breathing difficulties, the Allergy Specialists at Baby Memorial Hospital (BMH) offer advanced Allergy Immunotherapy for safe, long-term relief.
