Asthma inhalers: technique & spacers — pharmacist-reviewed guide

Also known as inhaler technique, asthma pump, spacer device.

This page is general health information, not a diagnosis. Always consult a licensed clinician about your own health.

What this covers

Inhalers deliver asthma medicine straight to the lungs, but most people use them incorrectly, so much of the dose never arrives. Knowing the difference between a daily preventer and a quick-relief inhaler — and using good technique, ideally with a spacer — transforms asthma control.

Safe-use guidance

  • Learn the difference: the reliever eases attacks fast; the preventer, used daily, stops attacks happening — both matter.
  • Shake (if applicable), breathe out fully, seal lips around the mouthpiece, press and breathe in slowly and deeply, then hold your breath for several seconds.
  • A spacer makes inhalers far easier and more effective, especially for children — ask for one.
  • Rinse your mouth after steroid preventer inhalers to avoid oral thrush.
  • Track how often you need your reliever — needing it more than a couple of times a week suggests poor control worth reviewing.
  • Keep a reliever accessible at home, work, or school, and check expiry dates.

Cautions

  • Using only a reliever while skipping the preventer leaves the underlying inflammation untreated — a common cause of severe attacks.
  • An attack not responding to the reliever is an emergency — seek urgent care.
  • Do not stop preventer inhalers when you feel well without medical advice.
  • Beware counterfeit inhalers from informal markets; buy from licensed pharmacies and check NAFDAC registration.
