Asthma inhaler: types, use and how to choose

A good inhaler can change how you breathe daily. Know the main types so you can use them well and pick the right one for your needs.

How to use your inhaler right

There are quick-relief inhalers (like salbutamol) and daily controller inhalers (steroid or combination). Metered-dose inhalers (MDIs) spray a measured dose; dry powder inhalers (DPIs) release medicine when you inhale; soft-mist inhalers make a slow mist; nebulizers turn medicine into a fine mist for a mask. Each device needs a slightly different technique.

MDI tips: shake the inhaler, breathe out, place the mouthpiece between your teeth, start a slow deep breath and press the canister once. Hold your breath for 5-10 seconds, then breathe out slowly. If you struggle with timing, use a spacer - it catches the spray so you can inhale at your own pace.

DPI tips: you usually load a dose, exhale away from the device, then take a fast, deep breath in to draw the powder into your lungs. No shaking. If you can't inhale strongly, a DPI may not give you the full dose.

Cleaning matters: wipe the mouthpiece weekly, keep caps on, and check expiry dates. Replace spacers every year or as your clinic suggests. Dirty or clogged devices can cut dose delivery dramatically.

Picking the right inhaler and staying safe

Age, coordination, breathing strength, and how often you need relief all matter. Kids and older adults often do better with spacers or nebulizers. If you travel a lot, choose a compact, easy-to-use device and carry a prescription and written action plan.

Know the meds: short-acting bronchodilators ease sudden symptoms; inhaled corticosteroids reduce inflammation over time; combination inhalers add both effects for regular control. Ask your prescriber which class fits your pattern of attacks and side-effect risk.

Watch for overuse of reliever inhalers - frequent need means poor control and a visit to your doctor. Also track canister doses: many inhalers have counters; if not, note the start date and number of doses used.

Buying inhalers online? Use licensed pharmacies, require a valid prescription, and check reviews and contact info. Our guide on Ellipta inhalers covers specific brands like Anoro and Trelegy if you want deeper comparisons.

If you're unsure about technique, ask your pharmacist or nurse for a quick demo. A one-time check often improves delivery more than changing drugs. Small changes in how you inhale can make a big difference in symptom control and overall quality of life.

Make an action plan: note which inhaler to use for rescue and which for daily control, set reminders for refills, and keep a spare inhaler at home and another at work or school. Store inhalers at room temperature, away from heat and freezing. Tell teachers or coworkers where your inhaler is and how to help if you have trouble breathing. Finally, bring your inhaler to every medical visit so the team can check technique and dose. Good technique means fewer attacks and better everyday breathing daily.
