Inhaler Guide: How to Choose, Use, and Care for Your Inhaler
If you’ve ever been told to grab an inhaler during an asthma flare, you know the feeling of urgency. But most people never learn the basics – which inhaler is best, how to get the full dose, and how to keep it clean. This guide breaks everything down in plain language so you can feel confident every time you reach for that device.
Types of Inhalers You’ll Meet
There are three main families of inhalers, and each works a little differently.
Metered‑dose inhalers (MDIs) look like small spray cans. They release a mist of medication when you press down. They’re the most common, especially for quick‑relief rescue meds.
Dry‑powder inhalers (DPIs) contain medication in a powder form. You breathe in sharply, and the powder lifts into your lungs. No propellant, but they need a fast, deep breath to work.
Soft‑mist inhalers create a slow‑moving mist that feels softer on the throat. They’re great for people who find MDIs too harsh.
Choosing the right one depends on your diagnosis, how well you can coordinate a breath, and personal preference. Ask your doctor which style fits your routine.
Step‑by‑Step: Using an Inhaler Properly
Getting the right dose isn’t magic—it’s about a few simple steps.
1. Shake the MDI (if you have one) for a few seconds. This mixes the medication.
2. Exhale fully away from the inhaler. Emptying your lungs makes space for the medicine.
3. Place the mouthpiece between your teeth and close your lips around it. For DPIs, load a dose first if required.
4. Press the can (MDI) or inhale sharply (DPI) while you start a slow, deep breath. Keep breathing in for about 3–5 seconds.
5. Hold your breath for 10 seconds if you can, then exhale slowly.
6. Repeat if your prescription says more than one puff. Wait about 30 seconds between puffs.
7. Rinse your mouth after using a steroid inhaler. This cuts down on throat irritation and yeast growth.
Missing any of these steps can waste medication and leave you feeling short‑of‑breath.
Cleaning, Storing, and When to Replace
Inhalers are reusable, but they need regular care. For MDIs, wash the mouthpiece with warm water weekly, let it air‑dry, and re‑attach. DPIs usually just need a dry wipe. Never soak any inhaler in liquid.
Store them at room temperature, out of direct sunlight. Extreme heat can change the medication’s potency.
Each inhaler comes with a dose counter. When it hits zero, throw it away – even if the can still feels like it has spray left. A dead inhaler won’t give you relief when you need it.
Common Mistakes and Quick Fixes
Not shaking an MDI – the spray can be uneven, giving you a weak dose.
Breathing in too fast with a DPI – the powder can stick to your throat instead of reaching the lungs.
Holding the inhaler too close to the mouth – you’ll get a spray that hits your tongue, not your airway.
If you notice a whistling sound, a blocked mouthpiece, or a strange taste, stop using it and get a replacement.
Remember, the inhaler is a tool you control. Knowing the type, mastering the technique, and keeping it clean will give you the best chance to stay breathing easy.
