Inhaler tips: simple steps to use and care for your inhaler

If your breathing depends on an inhaler, small habits make a big difference. Use the right technique, keep the device clean, and track doses so your inhaler works when you need it. Below are quick, practical tips you can start using today.

Quick steps for MDI (metered‑dose) and DPI users

MDI (spray) inhalers: shake the canister for 5 seconds, breathe out fully, put the mouthpiece between your teeth and seal with your lips, press once as you inhale slowly for 3–5 seconds, then hold your breath for about 10 seconds. If you need a second puff, wait 20–30 seconds and repeat. Use a spacer if you struggle to time the spray with your inhale — it makes delivery easier and reduces throat deposits.

DPI (dry powder) inhalers work differently: do not shake. Load the dose per the device instructions, breathe out away from the mouthpiece, then inhale forcefully and deeply to pull the powder into your lungs. Hold your breath for 5–10 seconds. If you feel powder on your tongue, you might not have inhaled hard enough. Practice a few times with your pharmacist or clinician watching — they can correct small mistakes that make a big difference.

Maintenance, storage, and smart habits

Prime new inhalers and those unused for a week or more. Priming is usually spraying into the air until a full dose appears; check the leaflet for exact steps. Always check the dose counter or mark the date you open the inhaler. Running out during a flare is the last thing you want.

Clean the mouthpiece weekly. For MDIs, remove the canister and wash the plastic holder in warm soapy water, rinse, and air dry. Don’t soak the metal canister. For DPIs, wipe the mouthpiece with a dry cloth — never use water unless the instructions say so. Keep covers on to stop dust and lint from blocking the opening.

Steroid inhalers need an extra step: rinse your mouth and spit after using them. This lowers the risk of thrush and hoarseness. If you get a sore white patch in your mouth, tell your doctor.

Store inhalers at room temperature away from direct heat and freezing cold. Extreme temperatures can change dose delivery. When traveling, keep the inhaler in your carry‑on so you always have it handy.

Track refills and know your backup. Keep a spare inhaler if possible and check expiry dates. If you notice reduced relief or need your rescue inhaler more often, call your clinician — that could mean your asthma or COPD needs treatment adjustment.

Want hands‑on help? Ask your pharmacist for a quick demo. A 5‑minute check can fix technique problems that months of poor control never will. Breathe easier by using these small, practical habits every day.
