If you have allergic rhinitis - sneezing fits, blocked nose, itchy eyes and throat that return every season or never quite leave - you have probably already done the usual circuit: antihistamines from the chemist, a nasal spray, perhaps an online blood test panel that flags half the world.
Those options can make symptoms quieter for a while. They do not change what your immune system does the next time it meets dust mite or pollen. Sublingual immunotherapy, or SLIT, works differently: it gives the immune system a tiny, controlled dose of the specific allergen every day until it gradually learns to tolerate it.
Why most allergy treatment stops halfway
Allergen immunotherapy is not new or experimental. It has more than a century of clinical history, and the sublingual route is used internationally for dust mite and pollen allergy. What matters is doing it properly: diagnosis first, matched allergens next, and follow-up throughout.
At HealthNest Clinic in Golf City, Lucknow, SLIT is offered as a supervised, test-guided programme. The goal is not another bottle for temporary relief. The goal is to identify what your immune system is reacting to and then train that reaction down over time.
A skin prick test shows what you are actually sensitised to during the same visit.
SLIT is not instant. Most patients notice change within the first half year.
Daily drops at home, with periodic reviews and medication tapering when appropriate.
The first dose is taken under supervision. Later doses are taken at home.
Who SLIT is for - and who it is not
We do not put every allergy patient on immunotherapy. It is the right tool for a specific group, and saying that upfront saves you a 3-year commitment you may not need.
SLIT is usually worth considering if you have:
- Allergic rhinitis that returns despite regular antihistamines and nasal sprays
- Confirmed dust mite or pollen sensitisation on skin prick testing
- Allergic symptoms alongside well-controlled allergic asthma
- A child with troublesome allergic rhinitis, after individual assessment
- Symptoms severe enough that you plan your day around them
SLIT is generally not the answer if:
- Your symptoms are mild and controlled with occasional medication
- Testing shows no genuine sensitisation matching your symptoms
- Your asthma is uncontrolled and needs stabilising first
- You know a daily routine for years is unrealistic right now
How the SLIT programme works at HealthNest
Consultation and skin prick test
We start with a detailed ENT and allergy history, nasal endoscopy where indicated, and a skin prick test against locally relevant allergens such as dust mites, pollens, moulds and animal dander. Results are available in about 20 minutes and are interpreted against your actual symptoms.
A customised prescription, not a generic bottle
Your drops are formulated for the allergens you are genuinely sensitised to. This is the step that separates supervised immunotherapy from unguided allergy drops dispensed without testing.
First dose under observation
You take the first dose in the clinic and stay for a short observation period. Serious reactions to SLIT are rare, but the first dose is where caution is cheapest.
Daily drops at home, reviews in clinic
After the first dose, you take one dose under the tongue daily at home. Review visits track symptom scores, help taper medicines as improvement develops, and keep the plan accountable.
Completion - and what you keep
After a completed course of around three years, the tolerance you have built typically persists for years after the last dose. Many patients stay off daily medication; most need substantially less.
The important rule: a positive allergy test alone is not enough. SLIT should target allergens that match both your test result and your real symptoms. Otherwise, three years of effort may treat the wrong problem.
Supervised by an allergy-trained ENT surgeon
Immunotherapy decisions sit at the junction of ENT and allergy medicine: whether your blocked nose is allergic at all, whether a deviated septum or polyps are confusing the picture, and whether asthma is stable enough to begin.
Dr. Akansha Tewari trained in both - postgraduate ENT at KGMU and a fellowship in asthma, allergy and immunology at AIIMS - and personally supervises testing, prescribing and follow-up for SLIT patients at HealthNest Clinic.
SLIT in Lucknow: honest answers
Does SLIT cure allergies permanently?
It is the closest thing allergy medicine has to a long-term fix - and "permanent cure" is still an overstatement. A completed course retrains the immune system so most patients end up with far fewer symptoms and far less medication, and the benefit usually persists for years after the drops stop.
How long before I notice a difference?
Usually between three and six months. You continue your regular antihistamines and sprays in the early phase, and we taper them as the immunotherapy takes effect.
Is it safe to take at home?
Home use is SLIT's main advantage over allergy injections. The first dose is observed in the clinic. The most common side effect is mild itching or tingling under the tongue during the first weeks, which usually settles on its own.
Can my child take SLIT?
Yes, generally from around five years of age, assessed case by case. Children are often the patients with the most to gain because treating allergic rhinitis early may reduce the risk of progressing to asthma.
How is SLIT different from allergy shots?
Both work on the same principle. Allergy shots require repeated clinic injections and observation. SLIT delivers the allergen as daily drops under the tongue at home after the first supervised dose, with a strong safety and convenience advantage for many patients.
Do I need an allergy test first?
Always. SLIT only works if it targets your actual allergens, so we skin prick test before anyone starts. Immunotherapy prescribed without testing is guesswork with a three-year price tag.
What if I miss doses or want to stop?
The occasional missed dose is manageable, and we will tell you how to resume depending on the gap. Abandoning the course early is the real cost because most of the long-term benefit comes from completing it.
What does SLIT cost in Lucknow?
It depends on how many allergens are being treated and the course duration, so exact figures are discussed openly after your skin prick test tells us what we are treating. Spread over the course, many patients compare it with the cumulative cost of years of medicines and repeat consultations.
Find out whether SLIT is right for you
One visit answers the practical question: consultation, skin prick test, and a straight recommendation - including "you do not need immunotherapy" when that is the truth. HealthNest Clinic serves patients from Golf City, Gomti Nagar, Sushant Golf City and across Lucknow.
