Childhood asthma and wheeze management
How asthma and wheeze in children are diagnosed and managed, including inhalers, spacers, a written action plan and knowing when breathing problems are an emergency.

In short
- Asthma causes wheeze, cough, breathlessness and chest tightness; in young children, wheeze with colds is common and a firm asthma diagnosis often waits until around age 5.
- Good control relies on the right inhalers used correctly with a spacer, avoiding triggers, and a written personal asthma action plan.
- A preventer inhaler (low-dose inhaled steroid) is often needed even when a child seems well, to keep the airways calm — it is not just for bad days.
- A child who is struggling to breathe, too breathless to talk/feed/play, or going blue-grey is an emergency — call 999.

What is childhood asthma and wheeze management?
Asthma is a common long-term condition where the airways become inflamed and narrow, causing wheeze, cough, breathlessness and a tight chest. In children, symptoms often come and go and are frequently triggered by colds, exercise, allergens (such as house dust mite or pets), cold air or smoke.
In younger children, doctors often talk about 'wheeze' rather than asthma, because wheezing with colds is very common in the preschool years and many children grow out of it. A firm diagnosis of asthma usually becomes possible from around age 5, when breathing tests can be done. Managing wheeze and asthma well means using the right inhalers correctly, avoiding triggers where possible, having a written action plan, and reviewing regularly.
Modern asthma care places a steroid-containing 'preventer' medicine at the centre of treatment for almost every child who needs regular treatment — a reliever inhaler used on its own is no longer considered enough for ongoing asthma. Exactly what is offered depends on your child's age. In under-5s, if symptoms or a severe episode suggest regular treatment is needed, the doctor may start a trial of a twice-daily low-dose steroid preventer (often for 8–12 weeks) alongside a reliever to use as needed, then review whether it has helped and whether asthma is the right diagnosis. Children aged 5–11 who are newly diagnosed are usually offered a twice-daily low-dose steroid preventer plus a reliever as needed; if control stays poor once the diagnosis, inhaler technique, how reliably the preventer is taken and the triggers have all been checked, treatment is stepped up along an age-appropriate pathway — this can include a 'MART' approach, where one combined inhaler (a low-dose steroid together with a fast-acting medicine called formoterol) is used both every day and for relief, for a child able to manage it. From age 12, a child may instead be given a combined low-dose steroid-and-formoterol inhaler to use only when symptoms occur (an 'anti-inflammatory reliever', or AIR), or a low-dose MART regimen from the start if symptoms are very troublesome or there has been a severe attack; anyone still using a reliever inhaler alone is moved onto a steroid-containing inhaler.
A spacer device makes inhalers far more effective for children of all ages. Asthma medicines and inhaler licences differ by age and by device, so your child should follow only the written plan their own clinician has given them, rather than copying another child's inhalers or doses.
Good management aims to keep your child free of symptoms, active, sleeping well and out of hospital. The most important safety point is recognising when breathing problems are an emergency: a child who is struggling to breathe, too breathless to talk, feed or play, or going blue needs 999 straight away.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Reliever vs preventer inhaler
| Feature | Reliever | Preventer |
|---|---|---|
| When used | During symptoms/attacks | Every day, even when well |
| How fast | Within minutes | Builds over days to weeks |
| Main job | Opens tight airways | Calms inflammation, prevents symptoms |
| Common colour | Often blue | Often brown/orange (varies) |
| Overuse meaning | Needing it a lot = poor control | Stopping it can let asthma return |
Always use inhalers with a spacer if advised. Needing the reliever three or more times a week usually means the plan needs reviewing.
Preparing for your treatment
- Keep a note of symptoms: when wheeze, cough or breathlessness happen, what triggers them, and how often the reliever is used.
- Bring all current inhalers and the spacer to every appointment so technique can be checked.
- Ask for inhaler technique to be watched and corrected — poor technique is a very common reason treatment 'fails'.
- Ask for a written personal asthma action plan and make sure you understand it.
- Note any night-time coughing, school absences or limits on play and exercise.
- Tell the clinician about allergies, eczema, hay fever, family history of asthma, and any smoke exposure at home.
- Make sure nursery or school has a copy of the action plan and a spare reliever and spacer if needed.
What happens
At a diagnosis or review appointment, the clinician asks about symptoms, triggers, how often the reliever is used, and the effect on sleep, play and school. They examine your child's chest and breathing.
In children from around age 5, objective tests may be used to support a diagnosis, such as measuring exhaled nitric oxide (FeNO), breathing tests (spirometry with a reliever to see if it helps), or peak flow readings over a couple of weeks. In younger children these tests are usually not possible, so a trial of treatment may be used instead.
Inhaler technique is checked and corrected, and the right device and spacer chosen. You will be given or updated with a written action plan that says which inhaler to use when, how to step up treatment for symptoms, and exactly when to seek urgent help. Treatment is then reviewed regularly and adjusted up or down based on control.
Is this treatment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Reliever-only treatment is not suitable for a child with frequent symptoms — untreated inflammation is dangerous and a preventer is usually needed.
- Breathing tests to confirm asthma are usually not suitable for very young children, so a trial of treatment is used instead.
- Managing 'asthma' is the wrong approach if symptoms are actually from another cause (such as inhaled object, reflux or a structural problem) — this needs assessment.
- Routine, repeated courses of oral steroids are not a substitute for good preventer use and review.
Delay or rearrange if…
- Your child is having an acute attack — this needs urgent treatment, not a routine review (call 999 if severe).
- Inhaler technique has not been checked, which can make treatment seem to fail before it is stepped up.
- A clear diagnosis is not yet possible in a young child and a trial of treatment is more appropriate than labelling.
- An alternative diagnosis (such as a swallowed object or persistent infection) needs ruling out first.
Alternatives to discuss
- Trigger avoidance and allergen control where allergies clearly worsen symptoms
- A leukotriene tablet or other add-on medicine if a low-dose preventer is not enough
- Combined-inhaler (MART/AIR) approaches in some older children
- Specialist paediatric respiratory referral for difficult or uncertain cases
- Watchful waiting in mild, infrequent preschool wheeze under review
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Fewer symptoms, so your child can sleep, play and exercise normally
- Fewer and less severe attacks, and fewer hospital visits
- Less time off school and fewer disrupted nights for the whole family
- A clear, written plan so you know what to do day-to-day and in an emergency
- Better long-term airway health when inflammation is controlled
- Confidence in recognising early warning signs and acting on them
Risks & complications
- Side effects of reliever inhalers such as a faster heartbeat or mild shakiness, usually brief
- Hoarseness or oral thrush from steroid inhalers (using a spacer and rinsing the mouth reduces this)
- Symptoms returning if the preventer is stopped or used inconsistently
- Poor inhaler technique making treatment seem not to work
- A mild effect on growth from inhaled steroids; the dose is kept as low as needed and growth is monitored
- Needing add-on medicines if a low-dose preventer is not enough
- Over-reliance on the reliever masking worsening control
- A severe asthma attack that needs emergency treatment or hospital admission
- Serious side effects from high-dose or oral steroids, used only when necessary and monitored
The greatest risk in childhood asthma is a severe attack that is not recognised or treated in time. Relying on the reliever inhaler while the underlying inflammation goes untreated is dangerous. Make sure your child has a current action plan, that inhaler technique is checked regularly, and that you know the emergency signs. If your child is struggling to breathe, too breathless to talk, feed or play, the reliever is not helping, or they go blue-grey, call 999.
Published figures to discuss
Outcomes in childhood asthma depend heavily on getting the diagnosis right, using inhalers correctly, and taking the preventer regularly. Many factors — age, triggers, adherence and technique — affect how well a child does and how likely attacks are. Robust single percentages for individual children are not meaningful, and figures for side effects and attacks vary widely, so they are not quoted here. The key point is that good control greatly reduces attacks, and recognising emergencies saves lives.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
Asthma is managed rather than cured, so 'afterwards' means how your child responds to treatment and how control is kept over time. Many children become symptom-free with the right plan used well.
- A short-lived faster heartbeat or mild shakiness after the reliever
- Symptoms easing gradually rather than instantly once a preventer is started
- Occasional symptoms during colds, which the action plan helps you manage
- Needing the reliever less often as control improves
Aftercare
- Use the preventer inhaler every day as prescribed, even when your child seems well.
- Always use a spacer if advised, and rinse the mouth after steroid inhalers to reduce thrush.
- Check and renew inhaler technique regularly — ask the nurse or pharmacist to watch it.
- Keep the reliever inhaler and spacer available at home, at school and when out.
- Avoid known triggers where possible, and keep your child's home smoke-free.
- Follow the written action plan to step treatment up early when symptoms start.
- Attend asthma reviews and keep vaccinations (including the children's flu vaccine) up to date.
- Know the emergency signs and exactly when to call 999.
- Written personal asthma action plan (a copy at home and at school)
- In-date reliever inhaler and a spacer
- Preventer inhaler with a routine to remember it daily
- Mouth-rinsing habit after steroid inhalers
- Symptom and reliever-use diary
- Spare inhaler and spacer for nursery or school
- Emergency plan and 999 advice understood by all carers
⚠ Get urgent help if…
- Struggling to breathe, breathing very fast, or sucking in under the ribs or at the neck — call 999
- Too breathless to talk, eat, feed or play, or lips/face going blue-grey — call 999
- The reliever inhaler is not helping, or is needed again within a few hours and symptoms are severe — call 999
- Grunting with each breath, or a baby/young child who is exhausted and floppy — call 999
- Reliever needed more than every 4 hours, night waking with cough or wheeze, or peak flow falling — contact your asthma clinician urgently
- A non-blanching rash, a child who will not wake, or a seizure (not typical of asthma but always urgent) — call 999
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

Results & realistic expectations
Well-managed asthma means your child has few or no symptoms, sleeps through the night, can play and exercise freely, rarely needs the reliever, and avoids attacks and hospital visits. Many children, especially preschool wheezers, improve as they grow.
Treatment controls asthma but does not cure it, and symptoms can return if the preventer is stopped or triggers change. A 'good' day does not mean the asthma has gone — keeping to the plan is what maintains control. Be cautious of any product or claim that promises to cure childhood asthma.
Asthma is a long-term condition that can change as a child grows. Many young children grow out of viral wheeze, while others continue to have asthma into later childhood and adulthood. Because the picture changes, the action plan and medicines should be reviewed regularly and adjusted, stepping treatment down when control is good and up when it is not.
Related tests, treatments or support
Asthma care often goes hand in hand with managing hay fever, eczema and allergies, which can share triggers and worsen symptoms. The yearly children's flu vaccine is recommended for children with asthma. Where allergies are a major trigger, allergy assessment may be combined with asthma management.
Follow-up & long-term care
Children with asthma should have a regular review (at least yearly, and after any attack) to check symptoms, inhaler technique, growth and the action plan. You should know who to contact between reviews, how to get repeat inhalers in good time, and when to seek urgent or emergency help.
- Take the preventer inhaler daily as prescribed, even when well
- Renew inhalers before they run out and check expiry dates
- Keep inhaler technique reviewed and spacers clean and replaced as advised
- Attend at least yearly asthma reviews and a review after any attack
- Keep the action plan up to date and shared with school and carers
- Have the children's flu vaccine each year where offered
Repeat, follow-on and what comes next
- Treatment is stepped up and down over time based on control; changing the plan is normal, not a failure.
- A trial of a preventer in young children may be stopped if it clearly does not help.
- Asthma can return or worsen with new triggers or as a child grows, so reviews and adjustments continue.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A written, up-to-date personal asthma action plan understood by parents and school.
- Regular reviews (at least yearly and after any attack) with inhaler-technique checks.
- Clear emergency instructions, including exactly when to call 999.
- Easy access to repeat inhalers and a named contact for between-review concerns.
- Growth monitoring and keeping the steroid dose as low as effective.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether care is with a GP/nurse or a private paediatric respiratory specialist
- Number and length of appointments and reviews
- Any objective tests used (such as FeNO measurement or spirometry)
- Allergy testing if triggers are being investigated
- Inhaler devices, spacers and any add-on medicines
- Follow-up reviews and updates to the action plan
- Who provides care and their paediatric/respiratory experience
- What each appointment and any tests include
- Whether inhaler technique checks and a written action plan are included
- Cost of any allergy testing or breathing tests
- How prescriptions, devices and follow-up are handled and charged
- What happens in an emergency and how urgent advice is accessed
- How care is shared with your NHS GP
On the NHS? Asthma diagnosis, inhalers and reviews are provided on the NHS; some families use private care for a faster appointment or a specialist respiratory opinion, but ongoing care is usually shared with the GP.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not being shown or having inhaler/spacer technique checked.
- No written action plan, or no clear emergency (999) advice.
- Being led to believe a preventer is only for bad days.
- Side effects of inhaled steroids overstated so the preventer is avoided, leaving asthma untreated.
- No plan for who sees the action plan at nursery or school.
Marketing red flags
- Claims to 'cure' childhood asthma or remove the need for inhalers.
- Unproven breathing 'therapies', supplements or devices sold as alternatives to inhalers.
- Allergy 'cures' promoted as a way to stop asthma medicines.
- Downplaying the importance of the preventer inhaler or the action plan.
- Selling tests or treatments without checking inhaler technique and basic control first.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Is this asthma or viral wheeze, and how confident are you at my child's age?
- Which inhaler is the reliever and which is the preventer, and exactly when should each be used?
- Can you watch and correct my child's inhaler and spacer technique?
- Can I have a written action plan, and what are the signs that mean I should call 999?
- What triggers should we try to avoid, and would allergy testing help?
- How often will my child be reviewed, and how do we step treatment up or down?
- How will you keep the steroid dose as low as possible and monitor growth?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my treatment, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this treatment not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
