At a glance
- Wheezing does not always mean asthma, especially in young children with viral infections. Repeated episodes, night cough or limits on play need assessment; testing may include spirometry when the child can perform it.
- Reliever medicines treat symptoms quickly; controller treatment helps prevent symptoms and attacks. Some prescribed plans use one specific combination inhaler for both roles. Confirm each medicine’s role and exact instructions with the clinician; do not swap inhalers or change doses using this page.
- Keep an up-to-date, clinician-written asthma action plan stating the child’s medicines, early warning signs, escalation steps and emergency contacts. Give the official plan to school, childcare and other caregivers, with any required medication forms.
- Use a spacer or holding chamber only with a compatible metered-dose inhaler. Dry-powder and breath-actuated inhalers have different instructions. Ask a clinician or pharmacist to demonstrate the exact device, then show the technique back; a young child may need a well-fitting mask.
- Colds and other respiratory viruses, smoke, air pollution and relevant allergens can trigger symptoms. Keep the home and car smoke-free, identify the child’s own triggers, and discuss a plan that allows normal play and exercise.
- Call local emergency services now for severe or rapidly worsening breathing difficulty, inability to speak or feed because of breathlessness, blue or gray lips, marked pulling in around the ribs or neck, unusual drowsiness or confusion, or an attack not improving with the prescribed reliever. Follow the emergency steps in the child’s asthma action plan while help is coming. Do not delay for this diary.
Symptoms and diagnosis
Asthma causes episodes of narrowed, inflamed airways. Cough, wheeze, chest tightness or breathlessness may vary over time; a clinician must assess the pattern and other possible causes.

When breathing needs urgent help
Call local emergency services now for severe or rapidly worsening breathing difficulty, inability to speak or feed because of breathlessness, blue or gray lips, marked pulling in around the ribs or neck, unusual drowsiness or confusion, or an attack not improving with the prescribed reliever. Follow the emergency steps in the child’s asthma action plan while help is coming. Do not delay for this diary.
New or ongoing wheeze, breathing difficulty, frequent night waking, reduced activity or needing reliever medicine more often than the action plan allows needs prompt medical advice. Follow the existing plan; arrange urgent assessment for current breathing symptoms. Severe symptoms or failure of the reliever require emergency help.
Medicines and the written action plan
Reliever medicines treat symptoms quickly; controller treatment helps prevent symptoms and attacks. Some prescribed plans use one specific combination inhaler for both roles. Confirm each medicine’s role and exact instructions with the clinician; do not swap inhalers or change doses using this page.

Inhalers and spacer technique
Use a spacer or holding chamber only with a compatible metered-dose inhaler. Dry-powder and breath-actuated inhalers have different instructions. Ask a clinician or pharmacist to demonstrate the exact device, then show the technique back; a young child may need a well-fitting mask.
For a prescribed metered-dose inhaler with a spacer, use the taught mouthpiece or mask seal and give one puff into the chamber at a time. Follow the device instructions for breathing, priming, shaking and cleaning, and the clinician’s instructions for the total prescribed dose.
Triggers, school and follow-up
Colds and other respiratory viruses, smoke, air pollution and relevant allergens can trigger symptoms. Keep the home and car smoke-free, identify the child’s own triggers, and discuss a plan that allows normal play and exercise.
Record daytime symptoms, night waking, limits on activity and reliever use for the review visit. Bring every inhaler and spacer so technique, dose counters, expiry dates and access can be checked. Keep follow-up visits even when the child feels well.
