About one in ten Indian children has asthma. About nine in ten of those children are on the wrong dose, the wrong device, or no controller medicine at all.
Severe breathing difficulty, chest indrawing, blue lips, drowsiness, poor feeding, grunting, pauses in breathing, persistent fast breathing, low oxygen — these are not for online review. Go to in-person pediatric emergency care.
What asthma actually is.
Most parents picture asthma as the moments — the wheeze, the cough, the chest tightness. The disease itself is in the calmer hours.
The lining of the airways in a child with asthma is, even between attacks, mildly inflamed. Sensitive. Quick to react. The attack happens when something — a cold, exercise, cold air, an allergen — meets airways already primed to overreact.
The point matters because it tells you what the medicine is doing. The reliever inhaler treats the moment. The controller inhaler treats the inflammation that creates the moments. One opens the airway. The other prevents the next time it closes.
This is why a child whose asthma seems "fine, only acts up sometimes" still benefits from a daily controller. The medicine is doing its work in the calm hours, where you can't see it.
Why so many cases get the wrong name.
"Allergic bronchitis." "Frequent chest infections." "Weak chest." "Low immunity." These are not diagnoses. They are descriptions written down when the actual diagnosis hasn't been worked out.
The pattern repeats: a child has a cold, the cold leaves a cough that lingers for weeks, the cough comes back next month. An antibiotic is prescribed. The cough resolves. Everyone is satisfied. Six weeks later, it returns.
Most recurrent paediatric cough that follows this rhythm — repeating every few weeks, worse at night, worse with exercise — is undiagnosed asthma. Antibiotics achieve nothing for it. The label keeps the consultation moving forward; the underlying condition keeps progressing in the dark.
If your child has been treated for "allergic bronchitis" or "recurrent chest infections" for over a year, the question is fair, important, and often the moment things change. About a third of recurrent paediatric cough turns out to be asthma. The diagnosis gives you a treatment that actually works — usually a small daily dose of inhaled medicine, used correctly, that stops the cycle.
The technique problem — and the two-method correction.
There are actually two ways to use a spacer with an inhaler. Most parents are taught only one.
The everyday way — what your child should do during normal daily use: one slow, deep breath in through the spacer, then hold it for a moment. One puff, one slow breath, hold. That's it.
The during-an-attack way — when your child can't manage a deep breath: several normal breaths in and out through the spacer, five or six of them, then the next puff if needed.
Mixing them up — using the during-an-attack pattern as the daily routine — is one of the quiet reasons a child's medicine doesn't reach the lungs the way it should. The technique is the dose.
Updated international guidelines (GINA 2026) make this distinction explicit. The medicine, the prescription, the dose — none of it changes. What changes is whether the medicine actually lands where it needs to.
The five universal mistakes.
Almost every child using an inhaler wrong is making one of these five.
Most of the medicine hits the back of the throat, not the lungs. Drug delivery drops to about a tenth of what it could be. A spacer with a mouthpiece costs ₹400-800. There is no good reason for any child to be using an inhaler without one.
Even thirty seconds between shaking and pressing the inhaler can change the dose. Sometimes too much. Sometimes too little. The fix is small: shake, then immediately press. Every puff. Every time.
Only one puff gets effectively inhaled. The second collides with the first inside the chamber. Each puff needs to be inhaled separately, with about thirty seconds between puffs.
"Fits on" is not the same as "sealed against." Air leaks around the edges of an unsealed mask dilute the dose and disperse the medicine. The mask must be held firmly against both nose and mouth, with no visible gaps.
Wash with a drop of mild detergent. Don't rinse. Don't towel-dry. Just stand it up to air-dry overnight. Both the rinsing and the towel-drying undo what the detergent does — they reduce how much medicine reaches the lungs at the next dose.
Fix any one of these and drug delivery improves. Fix all five and the same prescription begins doing what it was designed to do.
The treatment, as it actually works.
Modern paediatric asthma treatment is built around a small daily dose of inhaled corticosteroid — the controller — and a reliever inhaler for symptoms.
The controller does the unseen work. It treats the inflammation in the airway lining, the work that stops the next attack from happening, that lets your child run, sleep, climb, play. It is small. It is local — it goes to the airways, not the body. And the side effect profile is well-understood and acceptable, particularly when weighed against the cost of untreated asthma on a child's growth, sleep, and learning.
The reliever opens the airway when something has narrowed it. Used alone, it treats the moment but not the cause. A child who needs a reliever often is a child whose controller plan needs review.
For children old enough — six and above — international practice now offers a single combined inhaler that can be used both as the daily controller and as the reliever. One device, one medicine. The simpler regimen is genuinely simpler, and significantly reduces both the number of attacks and the use of oral steroids over time.
When the inhaler isn't enough — biologic therapy.
For the small group of children whose asthma stays severe despite optimal inhaled treatment with verified technique and good adherence, there is a separate chapter of medicine called biologic therapy.
Biologics are injection medicines — given every two to four weeks for most, every six months for one of the newest — that target the specific immune signals driving severe asthma. Different biologics for different patterns of severe disease, identified through blood tests and a careful clinical history.
The newest biologic, available from this year, is given as an injection just twice a year. Six-month dosing instead of monthly. For a family navigating severe paediatric asthma, this is what progress actually looks like — not a cure, but a treatment burden that no longer dominates the calendar.
Biologics are expensive. The eligibility is specific. They are not the first answer, or the second — they come after standard treatment has been given a fair trial and found genuinely insufficient. But for the children who need them, they exist now in a way they did not five years ago. The first generic-equivalent biologic for severe allergic asthma also became available this year, which over time should improve access.
Beyond the lungs — the upper airway connection.
Treating asthma in a child who also has untreated allergic rhinitis is like trying to dry the floor with the tap still running.
The two conditions share immunology and influence each other. Children with both, treated for both, do consistently better than children whose asthma is treated alone. Many "uncontrolled asthma" cases improve dramatically once the runny nose, the post-nasal drip, and the chronic congestion get the treatment they always needed.
The same is true earlier in the journey. A baby with eczema, a toddler with food allergies, a school-age child with hay fever, a teenager with asthma — these are often the same child, traversing what's called the atopic march. Recognising the pattern early is what gives a paediatric pulmonologist the most leverage. The medicine is good. The treatment is well-tolerated. Most children, well-treated, never carry the limitations the diagnosis sounds like it should bring.
If your child has both food allergy and asthma.
A small but important rule: if a reaction begins that has features of both anaphylaxis and asthma — adrenaline first, inhaler second.
Anaphylaxis is faster and deadlier than asthma; the airways tighten in a different way; adrenaline addresses both at once. If your child carries an EpiPen and an inhaler, and is in a moment that could be either, the order is: EpiPen, then inhaler. Always.
It is a rule that matters once and only once — but on that occasion, more than almost anything else.
Lung function tests — what x-rays miss.
A chest x-ray of a child with asthma is, between attacks, almost always normal. The disease isn't structural. It's functional.
Two specialist tests measure what x-rays cannot:
- Spirometry — usable from age six. Measures how fast and how completely your child can blow air out. Detects airway obstruction and reactivity in the way doctors learn to interpret.
- Impulse oscillometry (IOS) — usable from age three. The child breathes normally through a mouthpiece while small pressure waves probe the airways. No effort, no held breath. Picks up the small-airway disease that spirometry can miss.
Both are quick. Both are non-invasive. Both, used at the right moment, find what's actually happening — or what definitely isn't.
What good control looks like.
If the treatment is working — and in well-treated childhood asthma, it almost always does — your child will:
- Sleep through the night without coughing or wheezing
- Run, climb, play sport without getting winded faster than peers
- Need the reliever inhaler rarely, perhaps a few times a year
- Miss school for asthma rarely, perhaps not at all in some years
- Grow normally, develop normally, be unburdened by the diagnosis
If your child is not doing these things, the plan needs work. "Mild asthma well-controlled" and "moderate asthma poorly controlled" can sit in the same prescription. The difference is in the technique, the adherence, and the diagnosis underneath.
This is what a structured paediatric pulmonology consultation is for: not to invent new medicine, but to make sure the medicine your child already has is reaching the right place, in the right amount, for the right reason.
