Immunotherapy in Kolkata: The Only Permanent Treatment for Allergy | Dr. Naren Pandey
By Dr. Naren Pandey | Allergist & Asthma Specialist, Kolkata
Are you tired of taking antihistamines every single day? Do your allergy symptoms keep coming back despite medication? Have you been told that allergy has no cure — and you will have to live with it forever?
If yes, there is good news. Allergy Immunotherapy — also known as the allergy vaccine — is the only scientifically proven treatment that addresses the root cause of allergy and provides long-term, often permanent relief.
At the Allergy Asthma Centre, Dr. Naren Pandey has successfully treated hundreds of allergy patients in Kolkata with immunotherapy — helping them breathe freely, live comfortably, and stop depending on daily medication. This complete guide explains what immunotherapy is, how it works, and whether it is right for you.
What Is Allergy Immunotherapy?
Allergy immunotherapy is a long-term treatment that gradually desensitises the immune system to the specific allergen causing your allergy symptoms.
In simple terms: your immune system has learned to overreact to a harmless substance — like dust mites, pollen, or mold. Immunotherapy re-educates your immune system to tolerate that substance — reducing or eliminating the allergic reaction permanently.
Unlike antihistamines and nasal sprays that only suppress symptoms, immunotherapy treats the underlying cause — making it the only disease-modifying treatment available for allergy.
How Does Immunotherapy Work?
Immunotherapy works through a process called allergen desensitisation:
Step 1 — Allergy Testing First, Dr. Naren Pandey identifies your exact allergen through a Skin Prick Test or IgE blood test. This is critical — immunotherapy must be targeted to your specific allergen to be effective.
Step 2 — Build-Up Phase Small, gradually increasing doses of the allergen extract are administered. Your immune system slowly learns to tolerate the allergen without overreacting.
Step 3 — Maintenance Phase Once the optimal dose is reached, regular maintenance doses are given. The immune system continues to build tolerance over time.
Step 4 — Long-Term Relief After completing the full course, most patients experience significant and lasting reduction in allergy symptoms — many achieve complete, permanent relief.
Types of Immunotherapy Available in Kolkata
At Allergy Asthma Centre, Dr. Naren Pandey offers two forms of immunotherapy:
Subcutaneous Immunotherapy (SCIT) — Allergy Injections
The most established and widely used form of immunotherapy worldwide.
- Allergen extract is injected under the skin (subcutaneous)
- Administered at the clinic under medical supervision
- Build-up phase: weekly injections for 6–12 months
- Maintenance phase: monthly injections for 3–5 years
- Most effective form — highest success rates
- Suitable for dust mite, pollen, mold, and insect venom allergy
Sublingual Immunotherapy (SLIT) — Allergy Drops
A newer, more convenient form of immunotherapy — taken at home under the tongue.
- Allergen extract drops placed under the tongue daily
- No injections — ideal for children and needle-phobic patients
- Can be taken at home — no clinic visits required for daily doses
- Slightly lower efficacy than injections — but very effective for dust mite allergy
- Available for dust mites, pollen, and grass allergy

Conditions Treated with Immunotherapy in Kolkata
Allergic Rhinitis (Nasal Allergy) Immunotherapy is the most effective long-term treatment for allergic rhinitis — reducing sneezing, nasal congestion, and runny nose permanently. Studies show 85% of patients experience significant improvement.
Allergic Asthma For patients whose asthma is triggered by dust mites or pollen, immunotherapy reduces airway inflammation and decreases the need for inhalers. It is the only treatment that can prevent asthma from worsening.
Urticaria (Hives) For allergen-triggered chronic urticaria, immunotherapy helps reduce recurrent hive episodes significantly.
Dust Allergy House dust mite immunotherapy is the most commonly administered treatment at our Kolkata clinic — with excellent long-term results.
Skin Allergy (Atopic Dermatitis/Eczema) Immunotherapy reduces the frequency and severity of eczema flare-ups in patients with identified allergen triggers.
Benefits of Immunotherapy

| Prevents new allergies | Reduces sensitisation to new allergens |
| Safe for children | From age 5 onwards |
| Cost-effective | Cheaper than lifelong medication |

Who Is a Good Candidate for Immunotherapy?
Dr. Naren Pandey recommends immunotherapy for patients who:
✅ Have confirmed allergy to dust mites, pollen, mold, or cockroach ✅ Have been suffering from allergy for more than 2 years ✅ Take antihistamines or nasal sprays daily ✅ Have allergic asthma triggered by an identified allergen ✅ Want permanent relief without lifelong medication dependence ✅ Are 5 years of age or older ✅ Are committed to completing the full treatment course

Immunotherapy is generally not recommended for:
❌ Severe uncontrolled asthma (FEV1 < 70%) ❌ Active autoimmune disease ❌ Certain heart conditions ❌ Pregnancy (can be continued if started before pregnancy) ❌ Patients on beta-blocker medications ❌ Children under 5 years of age
How Long Does Immunotherapy Take?

Patience is essential — immunotherapy is not a quick fix. However, most patients notice significant improvement within the first 3–6 months, which encourages them to complete the full course.

| Antihistamines | Immunotherapy | |
|---|---|---|
| What it treats | Symptoms only | Root cause |
| Duration of effect | While taking medication | Years after stopping |
| Daily medication | Required indefinitely | Not needed after course |
| Disease modification | No | ✅ Yes |
| Prevents progression | No | ✅ Yes |
| Side effects | Drowsiness, dry mouth | Minimal — local reaction |

Is Immunotherapy Safe?
Yes — immunotherapy has been used safely for over 100 years worldwide. At Allergy Asthma Centre, Dr. Naren Pandey follows strict safety protocols:
- Every injection is administered under medical supervision
- Patients wait 30 minutes after each injection for observation
- Emergency medication is always available
- Dose is carefully adjusted based on patient response
Common side effects (minor):
- Local redness or swelling at injection site
- Mild itching — resolves within hours
Rare side effects:
- Systemic reactions — managed immediately at the clinic
- Anaphylaxis — extremely rare, managed with emergency protocols
Sublingual immunotherapy (drops) has an even better safety profile — making it ideal for children.
Immunotherapy for Children in Kolkata
Children with allergic rhinitis, asthma, or dust allergy respond particularly well to immunotherapy. Early treatment in children:
- Prevents allergic rhinitis from progressing to asthma
- Reduces the development of new allergies
- Improves school performance and sleep quality
- Reduces sick days and hospital visits
Dr. Naren Pandey recommends immunotherapy for children aged 5 and above with confirmed allergen sensitivity.
What to Expect During Your Immunotherapy Journey
Month 1–3: Visits every week. Dose gradually increases. Some patients notice early improvement.
Month 3–6: Significant reduction in symptoms begins. Medication use decreases.
Month 6–12: Maintenance dose reached. Visits become monthly. Most patients experience major improvement.

“I always tell my patients — immunotherapy requires commitment, but the reward is freedom. Freedom from sneezing every morning. Freedom from inhalers. Freedom from daily antihistamines. That is what we aim for at Allergy Asthma Centre.” — Dr. Naren Pandey, Allergy Asthma Centre, Kolkata
