Quick Answer
Your inhaler may not work well if the medicine does not reach deep into your lungs. Common problems include poor timing, breathing at the wrong speed, failing to breathe out first, or not holding your breath afterward. Ask a healthcare professional to watch your technique whenever treatment seems ineffective.
WHY IT MATTERS
The Medicine Must Reach Your Airways
Asthma inhalers deliver medicine directly into the breathing tubes. If the device is used incorrectly, much of the dose may remain in the mouth or throat instead of reaching the lungs.
This can make an appropriate treatment seem ineffective.
Common Inhaler Mistakes
TECHNIQUE CHECK
Not breathing out first
Gently emptying the lungs creates room for the next breath of medicine.
Breathing at the wrong speed
Pressurised inhalers usually need a slow, deep breath. Dry-powder devices usually need a quicker, stronger breath.
Poor timing
With many pressurised inhalers, the canister must be pressed just as inhalation begins.
Not holding the breath
Holding your breath for up to 10 seconds, when comfortable, helps the medicine settle in the airways.
Missing preparation steps
Some devices need shaking, priming, loading, or a specific position before use.
Using an empty or blocked device
Check the dose counter, expiry date, mouthpiece, and cleaning instructions.
Treatment response
How Can I Tell It Is Working?
You may notice:
-
Less wheezing or chest tightness
-
Less coughing, especially at night
-
Easier breathing during normal activity
-
Fewer asthma flare-ups
-
Less frequent need for a reliever inhaler
Reliever inhalers may work within minutes. Controller inhalers often need regular use over days or weeks.
When to seek review
Ask for Help if Symptoms Are Not Improving
✔ You are unsure which technique applies to your device.
✔ You need your reliever more often than usual.
✔ You wake at night with cough, wheeze, or breathlessness.
✔ Symptoms continue despite regular treatment.
✔ You develop troublesome mouth, throat, or voice symptoms.
Severe breathlessness, blue lips, confusion, difficulty speaking, or rapidly worsening symptoms require urgent medical care.
Remember
-
Different inhalers require different techniques.
-
Do not stop a prescribed controller inhaler without medical advice.
-
A spacer can improve delivery from many pressurised inhalers.
-
Ask for your technique to be checked regularly.
