Asthma Inhaler Basics: Choose, Use, and Keep It Working

If you or someone you love lives with asthma, the inhaler is likely the most important piece of equipment at home. It’s not just a plastic tube – it’s the fast‑track to breathing easier when an attack hits. Below you’ll find the simple facts you need to pick the right inhaler, use it correctly, and keep it in top shape.

What Types of Inhalers Are There?

There are three main families you’ll see on pharmacy shelves:

• Metered‑Dose Inhalers (MDI) – the classic can‑like device that releases a spray of medication. Most rescue inhalers (like albuterol) are MDIs.
• Dry‑Powder Inhalers (DPI) – you breathe in a powdered dose. No propellant, but you need a strong, steady inhale.
• Soft‑Mist Inhalers – they create a gentle mist that stays in the mouth longer, making it easier to swallow the dose.

For kids or anyone who struggles with coordination, a spacer attached to an MDI can make a huge difference. It catches the spray so you can inhale it more slowly.

How to Use an Inhaler the Right Way

Even the best medication won’t work if you miss a step. Here’s a quick, no‑fluff routine for MDIs (the most common):

1. Shake the inhaler for 5 seconds.
2. Remove the cap and check that the mouthpiece is clear.
3. Exhale fully, but don’t blow into the inhaler.
4. Place the mouthpiece between your teeth, seal your lips, and start a slow, steady breath in.
5. Press the can once as you begin to inhale.
6. Continue breathing in for another 2‑3 seconds, then hold your breath for about 10 seconds.
7. Exhale slowly. If you need another puff, wait 30 seconds before repeating.

For DPIs, you skip the shaking and the press‑button step. Just load the dose, exhale away from the device, then inhale sharply enough to draw the powder in.

After each use, wipe the mouthpiece with a clean cloth and replace the cap. This cuts down on residue and the risk of thrush.

Cleaning, Storing, and When to Replace

Cleaning is painless: rinse the mouthpiece under warm water once a week, let it air‑dry, and never wash the canister itself. Store the inhaler at room temperature, away from direct heat or humidity – a bathroom cabinet is fine, but not the shower shelf.

Each inhaler comes with a dose counter. When it hits zero, toss it. Even if the medication looks fine, the propellant may be gone, and you won’t get the full dose.

Common Mistakes and Quick Fixes

People often forget to exhale before inhaling – that leaves less room for the medicine. Another frequent slip is holding the breath for too short a time; the drug needs a few seconds to settle in the lungs. If you’re using a spacer, make sure it’s clean and properly attached; a cracked spacer can waste medication.

Kids sometimes forget to seal their lips or breathe too fast. Turning the routine into a game (“Hold your breath like a superhero”) can help them remember.

When to Talk to Your Doctor

If you need to use your rescue inhaler more than twice a week, it’s a signal that your daily control medication might need tweaking. Also, a persistent cough, hoarseness, or weird taste after inhaling should be mentioned – it could be a side‑effect or an infection.

That’s the core of inhaler know‑how. Keep this guide nearby, follow the steps, and you’ll get the relief you deserve without any extra hassle.
