Asthma inhalers: types, technique, and picking the right one
Do you know there’s more than one kind of asthma inhaler—and that using the wrong technique can make your medicine nearly useless? This page gives clear, practical tips so you can use your inhaler correctly, choose the right device, and avoid common mistakes.
Quick overview: rescue vs controller and main device types
First, split inhalers into two jobs: rescue (quick relief) and controller (daily prevention). Rescue inhalers usually contain short-acting bronchodilators; controllers often contain inhaled steroids or long-acting bronchodilators such as tiotropium for some adults. The common device types are:
- Metered-dose inhaler (MDI): a press-and-breathe canister. Good with a spacer if coordination is hard.
- Dry powder inhaler (DPI): breath-activated powder. You need a quick, strong inhalation.
- Soft-mist inhaler: slower spray, easier to inhale for some people.
- Nebulizer: turns liquid medicine into mist—useful for young kids or severe attacks.
How to use your inhaler the right way
Technique differs by device, but here are simple, reliable steps that help most people:
For MDIs: shake the inhaler, breathe out, tilt your head back slightly, press the canister as you start a slow, deep breath, then hold your breath for about 10 seconds before exhaling. If you struggle with timing, use a spacer—spacers make the medicine easier to inhale and reduce throat deposits.
For DPIs: load the dose per the device instructions, breathe out away from the mouthpiece, close your lips around the mouthpiece, then inhale quickly and deeply. Hold your breath for about 10 seconds. Don’t shake DPIs.
For soft-mist inhalers and nebulizers: follow the device leaflet. Nebulizers need a steady mask or mouthpiece and typically run for 5–15 minutes.
Rinse your mouth after using inhaled steroids. This lowers the risk of oral thrush and hoarseness. Clean mouthpieces weekly and store devices away from extreme heat or moisture.
How will you know it’s working? Fewer night symptoms, less need for rescue inhaler, and better activity tolerance are good signs. If symptoms persist, ask your clinician to review your inhaler type and technique.
Thinking about buying inhalers online? Always keep these rules: you need a prescription for most inhalers, choose a licensed pharmacy, check clear contact details and reviews, and never buy unlabelled or very cheap products that seem too good to be true.
If you’re unsure which inhaler fits your age, coordination, or insurance, talk to your doctor or pharmacist. A quick technique check during a visit can change how well your medicine works.
