Asthma Inhalers: What They Are and How to Use Them Right
If you or someone you love has asthma, the inhaler is probably the most familiar piece of equipment in the house. But do you really know which inhaler does what, how to get the best dose, and how to keep it working?
Common Inhaler Types You’ll Meet
The market mostly offers two families: metered‑dose inhalers (MDIs) and dry powder inhalers (DPIs). MDIs look like small spray cans; they release a fine mist when you press down. They need a spacer or holding chamber for kids and people with weak hand strength.
DPIs are breath‑activated devices that deliver powdered medication. You simply inhale sharply, and the powder goes straight into your lungs. No propellant, no shaking required – but they need a fast, deep breath to work.
There’s also the soft mist inhaler, which creates a slower, longer‑lasting cloud of particles. It can be easier on the throat and often feels more natural for beginners.
Step‑by‑Step: Getting Your Dose Right
1. Shake it (MDI only). A quick shake mixes the medication evenly.
2. Exhale fully. Blow out all air before you bring the inhaler to your mouth – this clears space for the medicine.
3. Seal and inhale. Place the mouthpiece between your teeth, close your lips, and start a slow, steady breath (MDI) or a fast, deep breath (DPI). Press the canister at the start of the inhalation if you’re using an MDI.
4. Hold your breath. Keep the air in for about 10 seconds to let the medication settle.
5. Repeat if needed. Most rescue inhalers need just one puff, while controllers may require two – follow your doctor’s directions.
A common mistake is breathing too fast with an MDI or forgetting to shake it. If you’re unsure, practice in front of a mirror or ask a pharmacist for a quick demo.
Cleaning, Storing & Buying Tips
Keep the mouthpiece clean by wiping it with a dry cloth once a week. A soaked cotton swab can clear stubborn residue, but avoid getting water inside the device.
Store inhalers at room temperature, away from direct heat or moisture. Extreme cold can affect the propellant in MDIs, while too much humidity can clump DPI powder.
When you buy a new inhaler online, check that the seller is licensed and that the product shows an expiration date. Counterfeit inhalers may have no active ingredient or the wrong dose – not worth the risk.
If you travel abroad, bring a copy of your prescription and keep the inhaler in carry‑on luggage. Security scanners can sometimes flag it, but a doctor's note clears things up quickly.
When to Call Your Doctor
If you need to use your rescue inhaler more than twice a week, it’s a sign your daily controller isn’t doing enough. Also watch for wheezing that doesn’t improve within minutes – that could mean an attack is getting serious.
Regular check‑ups let you adjust dosage, switch inhaler types, or add new medications like leukotriene modifiers. Keeping the conversation open helps you stay in control of your asthma.
Understanding each inhaler’s quirks and mastering the technique takes a few minutes, but it can save hours of coughing later. Grab yours, give it a proper shake, and breathe easy – you’ve got this!
