Inhalers are among the most effective treatments for asthma and COPD, yet many people use them in a way that sends much of the medicine to the back of the throat instead of the lungs. The inhaler may be fine; the technique is the usual problem.

Common mistakes

  • Not breathing out first and then breathing in too fast or too slowly for that specific device.
  • Poor coordination with a pressurised inhaler: pressing the canister and breathing in at different moments. A spacer often helps — ask whether you should be using one.
  • Not holding the breath for a few seconds after inhaling, if advised.
  • Using the wrong breath for dry-powder devices: they need a quick, deep breath, unlike some other inhalers.
  • Not shaking the inhaler when it requires shaking, or using an empty device.
  • Skipping the preventer when well, and relying only on the reliever.
  • Mixing devices because they look alike, or not knowing which one is the reliever.

Make the technique check routine

Bring every inhaler to each visit and demonstrate how you use it. Small corrections often make a noticeable difference. Ask for the steps to be written down, and for a clear plan: which inhaler to use daily, which for symptoms, and what to do if you need the reliever more often than usual.

Using the reliever more and more? Needing a reliever inhaler more often than your plan allows is a sign control is slipping and needs a review, not a larger number of puffs.

Do not change doses or stop a preventer without medical advice. Written guidance from your own doctor always takes priority over general information.

Frequently asked questions

Should I rinse my mouth after using an inhaler?

For inhalers that contain a steroid, rinsing the mouth and spitting afterwards is commonly advised to reduce throat irritation and thrush. Follow the instructions given for your own inhaler.

How do I know how much medicine is left?

Many devices have a dose counter. If yours does not, ask your doctor or pharmacist how to track doses so you do not run out unexpectedly.
