A daily controller, used wrong, delivers about one-tenth of the dose to the lungs that the same controller, used right, would deliver. The medicine isn't broken. The technique is.
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.
The two-method correction.
There are actually two correct ways to use a spacer with an inhaler. Most parents are taught only one — and very often, the wrong one for their child's situation.
The everyday way, for normal daily use of a controller or reliever in older children: one slow, deep breath in through the spacer, then hold it for a moment. One puff, one breath, hold. That is the daily routine.
The during-an-attack way, when your child is breathless and can't manage a deep slow breath: several normal breaths in and out through the spacer — five or six is enough — then the next puff if needed.
For children under five, the during-an-attack method becomes the everyday method, because young children can't reliably manage the slow-and-hold pattern. The technique matches the situation, not the medicine.
This distinction is now explicit in the international guidelines updated this year. Mixing them up — using the during-an-attack pattern as the daily routine for a six-year-old who can manage the slow-breath technique — is one of the quiet reasons medicine doesn't reach the lungs the way it should.
The five universal mistakes.
Most of the medicine hits the back of the throat, not the lungs. A spacer with 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 changes the dose. Sometimes too much. Sometimes too little. 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 thirty to sixty seconds between puffs.
"Fits on" is not the same as "sealed against." Even small gaps allow air around the edges and dilute the dose. The mask must press firmly, with no visible gap.
Wash with a drop of mild detergent. Don't rinse. Don't towel-dry. Just stand it up to air-dry overnight. Both rinsing and towel-drying undo what the detergent does — they reduce how much medicine reaches the lungs at the next dose.
What you can actually do.
Two things, both small, both effective:
- Have someone watch your child use the inhaler. Not describe it. Watch it. The errors are visible in two minutes; the corrections take five.
- Practise the two methods with your child. The everyday slow-breath-hold for daily use. The during-an-attack tidal breathing for moments of breathlessness. Knowing both, and switching between them, is what separates the children whose asthma is controlled from those whose isn't.
None of this requires a different prescription. None of it requires more medicine. The medicine you already have, used correctly, is doing the work it was designed for. The technique is the dose.
Get the technique watched, not described.
A focused video consultation observes your child's technique live, identifies exactly what's going wrong, and walks you through the correction together.
Book a video consultation →The "allergic bronchitis" trap.
A diagnosis written into thousands of Indian prescriptions every day. It is not a real diagnosis — and the children who carry it for years are usually being treated for the wrong thing.
"Allergic bronchitis" is not a recognised diagnosis in any modern paediatric guideline. It is, almost always, one of three real conditions going unnamed.
The phrase persists because it sounds plausible — there's the cough, there's some allergic component, the antibiotic seems to help. But the persistence of the term has a cost. Children labelled with it for years are children whose actual condition is going untreated.
What it usually really is.
About three-quarters of children carrying an "allergic bronchitis" label have one of these:
- Cough-variant asthma. The cough is the only symptom. There may be no audible wheeze. The pattern: worse at night, after exercise, in cold air, after viral colds. Family history of allergic disease is common. Treats with a daily inhaled steroid, and resolves cleanly in most children.
- Allergic rhinitis with post-nasal drip. Mucus runs down the throat, especially at night. The cough is worse lying down, often with throat clearing. Treats with an intranasal corticosteroid plus saline. Resolves over four to six weeks.
- Post-viral airway sensitivity. The viral infection has resolved. The airways remain twitchy. The next viral cold — three weeks later — restarts the same cough. Antibiotics achieve nothing. A short course of inhaled steroid often does.
None of these conditions responds to antibiotics. Each responds well to its own correct treatment. The wrong label means the wrong treatment, and a child who stays sicker than they need to be.
Why the term persists.
"Allergic bronchitis" is a workable shorthand. It contains words parents recognise. It feels diagnostic without committing to anything specific. The antibiotic prescription that often follows resolves the secondary bacterial colonisation that sometimes accompanies these conditions, which makes everyone feel the treatment worked.
Three months later the cough returns. Another antibiotic. Another resolution. Another return. A child can carry this cycle for two or three years before someone asks the right question.
The right question.
Most paediatricians, asked directly, will spend the time to walk the differential. The history alone — when does it happen, what triggers it, what's the pattern over months — narrows the cause to two or three real possibilities in most cases.
If the answer is still "allergic bronchitis," it's worth asking: "Could this be cough-variant asthma? Could this be allergic rhinitis? Could this be post-viral airway sensitivity? What test or trial would distinguish them?"
A diagnosis given the right name.
A specialist consultation walks the differential, commits to a specific diagnosis, and gives you a treatment plan that actually works — usually a small daily medicine, used correctly, that ends the cycle.
Book a video consultation →Three antibiotic courses don't fix what isn't bacterial.
When the same recurrent cough has had four or five antibiotic courses in a year — the answer is rarely "the next antibiotic." The answer is usually "a different diagnosis entirely."
Indian children average six to eight viral respiratory infections a year. Most resolve in two weeks. The cough that comes back every few weeks for months is almost never the seventh viral infection in a row, and is almost never bacterial.
And yet the typical Indian response is another antibiotic. Over a year, this can mean four or five courses for what is fundamentally the same problem — and the same problem is almost never the one antibiotics treat.
When antibiotics are right.
The list is short:
- Confirmed bacterial pneumonia — fever, focal chest signs, suggestive imaging
- Bacterial sinusitis with prolonged or worsening course beyond ten days
- Whooping cough (pertussis), confirmed or strongly suspected
- Strep throat with a positive swab
- Tuberculosis — with combination therapy
When antibiotics are wrong.
Most paediatric outpatient cough presentations are not on the right list. They are these:
- Most viral upper and lower respiratory infections
- Most viral bronchiolitis
- Most acute bronchitis
- Cough-variant asthma — the largest single missed cause
- Post-viral airway hyperreactivity
- Allergic rhinitis with post-nasal drip
- Reflux-related cough
- Habit cough
None of these respond to antibiotics. Each responds to its own correct treatment. The persistence of the antibiotic-first reflex is doing measurable harm — to children, to families, and to the antibiotic resistance that everyone will eventually inherit.
The real cost.
Each unnecessary antibiotic course represents real money — multiplied across millions of children, a public health expense in the thousands of crores. Each contributes to the growing resistance that already complicates treatment of serious bacterial infections in Indian hospitals.
And — most importantly — each represents a missed opportunity to make the actual diagnosis. A child whose cough returns every six to eight weeks for two years is a child whose underlying condition is progressing untreated, while everyone treats what isn't there.
Night signs and day signs.
The night signs are obvious to anyone listening:
- Snoring three or more nights a week, regular and loud — not just with colds
- Pauses in breathing, sometimes followed by gasps or sudden movements
- Mouth open during sleep
- Restless sleep, sweating, sheets soaked
- Bedwetting in older children, especially after dry years
- Strange sleep positions — neck hyperextended, head off the pillow
The day signs are the ones that don't get connected to breathing at all — but they are often the most diagnostic:
- Mouth breathing at rest, even when not running or playing
- Persistent dark circles under the eyes
- Morning headaches
- Daytime tiredness — or, paradoxically in young children, hyperactivity
- Difficulty concentrating, dropping grades, behavioural problems
- Mood swings, irritability
The ADHD overlap.
Studies suggest a meaningful proportion of children with ADHD-like presentations actually have undiagnosed obstructive sleep apnoea. Treating the OSA — often curable with adenotonsillectomy or allergy management — can resolve symptoms that ADHD medication alone could not.
This doesn't mean ADHD isn't real. It is. It means that any child being evaluated for ADHD-like symptoms with snoring or other sleep concerns deserves a sleep evaluation as part of the workup.
What's different in children.
In adults, OSA is mostly about obesity. In children, it is mostly about anatomy.
The most common cause of paediatric OSA is enlarged tonsils and adenoids. These tissues normally peak around ages four to six, then regress. In children whose tonsils and adenoids stay disproportionately large, sleep airway obstruction follows.
Allergic rhinitis is a frequent co-driver. Chronic nasal blockage forces mouth breathing, which over years changes how the face and palate develop, which compounds the obstruction. Treating the rhinitis often resolves mild OSA without surgery, and improves outcomes alongside surgery in moderate cases.
Most paediatric OSA is fixable.
- Adenotonsillectomy — for moderate-severe OSA from enlarged tonsils and adenoids. Many children show transformation within months.
- Allergic rhinitis treatment — when AR is contributing, often resolves mild OSA without surgery.
- Weight management — for obese children, substantially improves OSA.
- CPAP — reserved for residual OSA after surgery, or where surgery isn't appropriate.
Snoring three or more nights a week is not, in a child, "just snoring." It is worth saying out loud, worth evaluating, and very often worth fixing.
If your child snores, get them assessed.
A consultation maps the night and day pattern, identifies the contributors, and tells you whether a sleep study or ENT referral is the right next step.
Book a video consultation →Why eczema in infancy matters.
A skin condition that looks cosmetic. A signal, often, of an immune trajectory that — recognised early — can be changed.
Eczema in an infant is treated like a skin problem. It usually is one. It is also, very often, the first visible signal of the atopic march — the immune trajectory that progresses from eczema to food allergy to allergic rhinitis to childhood asthma.
Not every infant with eczema follows this path. But a meaningful proportion do — and the ones who do are the ones who benefit most from being recognised early.
The atopic march.
The pattern is recognisable in retrospect, but better named in advance:
- Infancy: eczema, often starting on the cheeks, scalp, behind knees, inside elbows
- Toddler years: food allergies become apparent — egg, milk, peanut, tree nut
- Preschool to school age: allergic rhinitis appears, often year-round in Indian children
- School age onwards: asthma, sometimes preceded by recurrent "allergic bronchitis"
The conditions share immunology. They influence each other. A child further along the march has a higher likelihood of developing the next condition than a child who never started. Recognising the pattern early gives the most leverage.
What changes with early recognition.
An infant whose eczema is well-managed — proactively, with adequate emollients and topical anti-inflammatory treatment when needed — appears to have a lower risk of progression to food allergy and allergic rhinitis. The evidence isn't yet strong enough to call it definitive prevention. But it is enough to take the eczema seriously, and to treat it well, rather than waiting for it to "outgrow itself."
The same is true downstream. A child with allergic rhinitis, well-treated, often has fewer asthma symptoms when asthma develops. A child with food allergy, well-managed, has a clearer trajectory than one whose allergies are unrecognised. Each step on the march, treated well, changes what comes next.
What you can actually do.
- Treat the eczema as the medical condition it is. Daily emollients. Topical corticosteroid or non-steroidal anti-inflammatory when active. Adequate, not minimal — the under-treatment of paediatric eczema is the most common preventable contributor to its persistence.
- Recognise the next step early. Food reactions, persistent runny nose, recurrent night cough — each deserves the right evaluation rather than dismissal as separate small things.
- Treat each condition well as it appears. Allergic rhinitis. Asthma. The treatments are good. The outcomes, with consistent care, are usually unburdened.
Most children on the atopic march, well-cared-for through it, arrive at adulthood without significant residual disease. The earlier the recognition, the better the trajectory. A diagnosis that sounds heavy is, with the right care, often barely visible by the time the child is grown.
If your child is on the atopic march.
A specialist consultation maps where your child is on the trajectory, identifies the most useful next step, and builds the longitudinal plan that changes outcomes.
