Asthma flare-ups: what a written action plan should contain

KKH’s children’s emergency department saw about 2,800 asthma cases in 2023; around 1,000 required admission, according to its article on children living with asthma. The article asks parents to obtain a written action plan and follow its reliever instructions during an attack.
What information belongs in a written asthma action plan?
Record the medicines, warning symptoms and steps for getting help. In the 2026 Global Initiative for Asthma strategy, “written” includes digital and pictorial plans. The patient keeps the instructions. Age, reading needs, current asthma control and the actual regimen all affect what goes on the page.
The plan needs:
- the exact regular and reliever medicines;
- the person’s usual warning symptoms;
- clinician-set changes to reliever or maintenance treatment;
- whether peak flow is used, with the person’s reference values and thresholds;
- instructions for contacting the clinic, attending urgent care or calling an ambulance;
- copies for the people who may need to help, including caregivers, parents, school staff or workplace first aiders.
HealthHub’s asthma guidance describes parents, child and doctor making the plan together. GINA places it within guided self-management: symptom or lung-function monitoring, a documented plan and regular clinical review. Someone who cannot adjust their own treatment can still benefit from a structured programme of medical review. GINA reports reductions of one-third to two-thirds in outcomes such as asthma-related hospitalisations and emergency visits with this combined self-management education. That evidence concerns monitoring, the plan and regular review together, not handing out a form alone.
Why can two people with asthma have different instructions?
Their relievers may contain different ingredients and have different roles. Salbutamol is a short-acting bronchodilator. An eligible inhaled-corticosteroid and formoterol combination may be prescribed as an anti-inflammatory reliever, or for both maintenance and relief. GINA 2026 also recognises combined corticosteroid and short-acting bronchodilator relievers in some settings, abbreviated ICS-SABA.
GINA explicitly calls for an action-plan template appropriate to the reliever: ICS-formoterol, ICS-SABA or SABA. An anti-inflammatory reliever supplies inhaled corticosteroid alongside the rapid-acting bronchodilator when it is used. A SABA reliever does not contain that corticosteroid.
Do not copy another patient’s plan, an old regimen or a colour chart. The reliever versus preventer guide explains the ingredient names and prescribed roles. These need to match what is in the actual device.
| Plan element | What must be individualised | Why a generic instruction fails |
|---|---|---|
| Regular treatment | Ingredient, device, strength and prescribed schedule | Different controller and MART regimens do not use the same worsening steps |
| Reliever | Exact ingredient and role | A maintenance-only combination is not automatically a reliever |
| Early-warning signs | The person’s usual symptoms and functional changes | Wheeze may be absent; patterns differ by age and patient |
| Peak flow | Whether it is used and the person’s own reference values | A universal number ignores personal best and clinical context |
| Escalation | Named clinic, urgent-care and emergency steps | Access, history and risk of rapid deterioration differ |
What can signal that asthma is worsening?
Compare symptoms, night waking, activity and reliever use with your usual pattern. A flare-up is an acute or sub-acute worsening in symptoms and lung function. More cough, wheeze, chest tightness or breathlessness, reduced exercise or ordinary activity, disturbed sleep and increased reliever use can all be early signs. Some adults’ plans also use falling peak-flow readings.
HealthHub describes cough at night or after exercise and lists viral infections, cigarette smoke and haze among triggers. KKH points out that wheeze can be absent. These observations should trigger the instructions in the plan or a review if it is missing or out of date; they do not supply a medicine change by themselves.
At review, bring the inhalers as well as the symptom history. Increased reliever use may reflect poor technique, an empty device, missed maintenance treatment, infection, smoke or haze, or a diagnosis that needs reassessment. HealthHub gives a practical way to check supply: discard an inhaler when its counter reaches zero; for one without a counter, record use against the number of doses stated on the product.
Why do inhaler technique and supply belong in the plan review?
Have someone watch you use the inhaler and check the supply. GINA says errors often recur within 4 to 6 weeks of training. At the appointment, the clinician checks your technique against the checklist for that device, then shows you any corrections with a training inhaler or video. GINA allows for repeating this 2 or 3 times in the same session. It recommends trying another device only if repeated training has not resolved the difficulty.
For a metered-dose inhaler, HealthHub’s device guide describes a slow, steady breath coordinated with pressing the canister. Pressing too early or late, opening the mouth as the spray hits the throat, shallow inhalation and a short breath-hold can interfere with delivery to the lungs. A spacer can help with those problems. Dry-powder and other devices have different inhalation requirements; the same technique cannot be assumed for all of them.
Bring the spacer too. Check the remaining supply, expiry dates and duplicates with the clinician or pharmacist. The plan needs ingredient names and current instructions; old inhaler colours should not remain after a regimen change.
What changes the answer?
Age, the reliever regimen and previous attacks shape the instructions. A child’s plan has to work for parents, teachers and caregivers. Pictures may be more useful than dense text. In KKH’s article, Dr Ting Chun Yi and Dr Leon Tan Yuan Rui describe their picture book, Wallace’s Song, about a young whale who neglects his prescribed inhalers and has an asthma attack. Their purpose is to help children understand the condition and regular preventer use.
A history of severe or rapidly developing attacks may mean earlier assessment and a lower threshold for help. SABA, ICS-formoterol and ICS-SABA need different worsening instructions. Pregnancy and other conditions belong in the individual review, with maintaining asthma control still important.
Many plans use symptoms. If an adult’s plan uses peak flow, GINA favours personal-best readings over a percentage of predicted values. Correct meter technique matters too. Family, school, travel and work arrangements determine who needs the plan and access to emergency medicines.
Which signs need emergency help?
Call emergency services when breathing is severe or rapidly worsening, or the person cannot speak normally. A reliever that fails to help as the plan expects, or blue or grey lips or face, also calls for emergency assessment. Follow the plan’s emergency section.
Drowsiness, confusion and a silent chest need immediate acute care. GINA explains why wheezing may disappear in a severe attack: too little air is moving through the airways. HealthHub describes children gasping for air, unable to speak, sometimes with blue lips or fingertips. Do not wait for louder wheezing before getting help.
Do not delay help to obtain peak flow when someone is severely unwell. An online dose schedule cannot replace emergency assessment. Report facial or tongue swelling or collapse as well: asthma and anaphylaxis have different immediate treatment priorities.
What should happen after a flare-up or near miss?
Arrange follow-up and review the plan, including what was unclear during the episode. GINA advises early follow-up after an exacerbation wherever it was managed. Its discharge guidance for adults and adolescents specifies an appointment within 2 to 7 days; for school-age children it gives 2 to 5 days, adjusted to the clinical and social context.
Go through symptoms before the flare, inhalers actually used, technique, missed treatment, side effects and triggers. Review the anti-inflammatory treatment and confirm the next appointment. Repeated worsening or instructions that were hard to follow also warrant a plan review.
If you have no written plan, request one at the next asthma review and take every device. The asthma condition page can help with questions and terminology. The treating clinician needs to fill in your medicine-change and emergency instructions.
