What is allergy immunotherapy (allergy shots) and how does it help children with allergies?
Quick Answer
Allergy immunotherapy, or allergy shots, is a treatment that gradually reduces your child's sensitivity to allergens.
It works by exposing them to tiny, increasing amounts of the allergen over time.
This helps their immune system build tolerance, leading to fewer allergy symptoms.
The process requires commitment, often spanning months or years, but can significantly improve a child's well-being.
Recommended Practices
Consult an Allergist/Immunologist
The first step is to consult with a qualified allergist or immunologist.
They will perform allergy testing (skin prick or blood tests) to identify specific triggers.
Discuss your child's medical history and current medications with the doctor.
Understand the Treatment Plan
The allergist will create a personalized immunotherapy plan.
This involves a series of injections containing small amounts of the identified allergens.
Understand the schedule, dosage, and potential side effects.
Ask questions until you feel comfortable with the plan.
Adhere to the Injection Schedule
Consistency is key for successful immunotherapy.
Stick to the injection schedule provided by the allergist.
Missing doses can disrupt the process and reduce effectiveness.
If you have to reschedule, do so promptly.
Monitor for Side Effects
After each injection, monitor your child for any side effects, such as redness, swelling, or itching at the injection site.
Mild reactions are common, but severe reactions (difficulty breathing, hives) require immediate medical attention.
Keep an epinephrine auto-injector (if prescribed) readily available and know how to use it.
Create an Allergy-Friendly Home Environment
While undergoing immunotherapy, minimize allergen exposure at home.
Use allergen-proof bedding covers, vacuum regularly with a HEPA filter, and control dust mites.
For pollen allergies, keep windows closed during peak pollen seasons and use air purifiers.
Maintain Open Communication with the Allergist
Regularly communicate with the allergist about your child's progress and any concerns.
Report any changes in symptoms or side effects.
The allergist may adjust the treatment plan based on your child's response.
Follow-up appointments are crucial for monitoring progress.
What to Avoid
Stopping Treatment Prematurely
Immunotherapy requires a long-term commitment.
Stopping treatment before the recommended duration (usually 3-5 years) can lead to a relapse of allergy symptoms.
Even if your child feels better, continue the treatment as prescribed by the allergist.
Ignoring Mild Side Effects
While mild reactions are common, ignoring them can lead to complications.
Report any side effects to the allergist, even if they seem minor.
They can provide guidance on managing the reactions and adjust the dosage if necessary.
Relying Solely on Immunotherapy
Immunotherapy is most effective when combined with other allergy management strategies.
Continue to avoid known allergens and use prescribed medications (antihistamines, nasal sprays) as directed by the doctor.
Immunotherapy is not a quick fix but a long-term solution.
Using Expired Epinephrine
If your child has been prescribed an epinephrine auto-injector, check the expiration date regularly.
Expired epinephrine may not be effective in an emergency.
Replace it before it expires and ensure you and other caregivers know how to administer it properly.
Assuming Immunotherapy is a Cure
Immunotherapy aims to reduce sensitivity to allergens, but it may not completely eliminate allergies.
Some children may still experience mild symptoms, especially during peak allergy seasons.
The goal is to improve their quality of life and reduce the need for medications.
Neglecting Environmental Control Measures
Even with immunotherapy, it's important to minimize allergen exposure at home.
Dust mites, pollen, and pet dander can still trigger symptoms.
Maintain a clean and allergy-friendly environment to support the effectiveness of the treatment.
Common Scenarios and Solutions
My child is afraid of needles and refuses to get the allergy shot.
Talk to your child about the benefits of allergy shots in a calm and reassuring manner.
Use positive reinforcement and rewards to encourage them.
Ask the allergist about techniques to minimize pain and anxiety, such as using numbing cream or distraction methods.
Consider bringing a favorite toy or book to the appointment.
My child developed a large, itchy bump at the injection site.
Apply a cold compress to the injection site to reduce swelling and itching.
You can also use an over-the-counter antihistamine cream or lotion.
If the reaction is severe or spreads beyond the injection site, contact the allergist for further guidance.
They may recommend an oral antihistamine or a topical corticosteroid.
We are traveling and will miss a scheduled allergy shot appointment.
Contact the allergist as soon as possible to reschedule the appointment.
Try to schedule it as close to the original date as possible to minimize disruption to the treatment plan.
The allergist may provide specific instructions based on the length of the delay.
My child is still experiencing allergy symptoms despite being on immunotherapy.
Continue to follow the allergist's instructions regarding allergen avoidance and medication use.
It may take several months to see significant improvement with immunotherapy.
Discuss your concerns with the allergist.
They may adjust the dosage or add other medications to help manage your child's symptoms.

Signs to Consult Immediately
Difficulty breathing or wheezing
Hives or rash
Swelling of the face, lips, or tongue
Dizziness or loss of consciousness
Severe abdominal pain or vomiting
Any other signs of a severe allergic reaction (anaphylaxis)
Detailed Explanation
Allergy immunotherapy works by gradually desensitizing the immune system to specific allergens.
When a child with allergies is exposed to an allergen, their immune system overreacts, releasing histamine and other chemicals that cause symptoms like sneezing, runny nose, itchy eyes, and skin rashes.
Immunotherapy introduces small, controlled doses of the allergen, prompting the immune system to build tolerance over time.
The process involves two phases: build-up and maintenance.
During the build-up phase, the dosage of the allergen is gradually increased with each injection.
This phase typically lasts for several months.
Once the maintenance dose is reached, the child receives injections at regular intervals (usually every 2-4 weeks) for 3-5 years.
The maintenance phase helps to sustain the tolerance achieved during the build-up phase.
It's important to understand that immunotherapy is not a quick fix.
It requires a long-term commitment and consistent adherence to the treatment plan.
The benefits of immunotherapy may not be noticeable for several months, and it can take years to achieve maximum improvement.
However, many children experience significant relief from allergy symptoms and a reduced need for medications.
Normal developmental expectations are not directly affected by allergy immunotherapy itself.
However, uncontrolled allergy symptoms can impact a child's sleep, concentration, and overall well-being, which can indirectly affect their development.
By reducing allergy symptoms, immunotherapy can help children participate more fully in activities and reach their developmental potential.
Warning signs that require medical attention during immunotherapy include severe allergic reactions (anaphylaxis), such as difficulty breathing, wheezing, hives, swelling of the face or throat, and dizziness.
These reactions are rare but require immediate treatment with epinephrine.
Other warning signs include persistent or worsening side effects, such as fever, joint pain, or swollen lymph nodes.
The guidance for immunotherapy remains generally consistent across different age groups, but the dosage and frequency of injections may be adjusted based on the child's weight, age, and response to treatment.
For premature babies or those with health conditions, the allergist will carefully assess the risks and benefits of immunotherapy and tailor the treatment plan accordingly.
Special considerations may be needed to minimize the risk of side effects.
In India, seasonal allergies vary depending on the region and climate.
Pollen allergies are more common during spring and autumn, while dust mite allergies can be prevalent year-round, especially in humid environments.
During the summer, heat and humidity can exacerbate allergy symptoms.
During the monsoon season, mold allergies can be a concern.
In winter, indoor allergens like dust mites and pet dander may be more problematic.
Adjusting environmental control measures and medication use based on the season can help manage allergy symptoms effectively.
