Inhaler Technique: Check The Actual Device

The best inhaler technique is the one taught and checked for your actual prescribed device. Knowing a medicine’s name is not enough. BTS/NICE/SIGN recommends explaining the contents, purpose, timing and technique, then observing the person use the inhaler. This UK asthma guidance supports device-specific teaching, not a single operating sequence for every inhaler.

Start by identifying what you have

A pressurized metered-dose inhaler and a dry-powder inhaler are not interchangeable instruction sheets. MedlinePlus explicitly excludes dry-powder devices from its no-spacer MDI guide. Do not assume all inhalers should be shaken, breathed through with the same effort or paired with the same accessory.

Bring the actual inhaler and any prescribed accessory to the clinician or pharmacist. Ask them to identify it and watch how you normally use it. The UK guideline’s observation recommendation is useful because a demonstration can reveal a problem that “I know how” does not explain. If hand movement, reading, memory or another practical difficulty interferes, say so. Device suitability is a care question, not a test of determination.

Learn the differences that matter

Ask the teacher to separate preparing the device, taking the medicine, checking what remains and caring for the equipment. NG245 calls for correct technique for each device. MedlinePlus directs readers to their own inhaler’s priming instructions, illustrating why generic directions need limits.

Use the written instructions for the exact product. If a spacer or other accessory is part of the prescription, ask the team to confirm the pairing and show the whole setup. This article has not inspected a particular device’s instructions and cannot establish compatibility, a cleaning method or a replacement interval.

Before leaving, demonstrate the sequence yourself and ask about any step you cannot reproduce. Keep the correct leaflet accessible. A teaching session is more useful when it ends with a resolved question than when it ends with an unexplained set of steps.

Repeat the check when circumstances change

NG245 recommends checks at asthma reviews, when control deteriorates, when devices change and when someone requests help. Needing another demonstration is therefore an ordinary reason for contact. A device switch deserves teaching even if the medicine seems familiar.

If symptoms persist, report both what you are experiencing and any uncertainty using the device. The guideline includes adherence and technique in review; it does not support assuming a higher medicine dose is automatically the next step. Technique advice also does not replace your existing action plan for worsening asthma. The practical endpoint is a device you can use as instructed and a clear contact when that is not possible.
