Here are 10 common mistakes made when using a metered-dose inhaler (MDI) and how to correct them. 1. Slouching FIX IT: Sitting up straight or standing allows the lungs to fully inhale and provides more power to exhale. 2. Using an empty inhaler FIX IT: Request a refill when the inhaler has 30 puffs or doses left. 3. Not shaking or priming the inhaler* FIX IT: Shake the inhaler canister 10 to 15 times for the medication to be ready to work. When using a new inhaler, prime it by releasing three to four test sprays. Prime again if not used for several weeks. *This tip applies to MDI inhalers. Not all inhalers require shaking. 4. Using an MDI inhaler without a spacer FIX IT: A spacer helps more of the medicine get to the airways. Insert the inhaler into the spacer. Spray one puff of medicine and inhale slowly. Hold your breath for a count of 10 and exhale slowly. 5. Spraying several puffs of inhaler into spacer FIX IT: Spray only one puff of the inhaler into the spacer for each breath. Breathe out before inhaling. Inhale and hold your breath for a count of 10, then exhale. Repeat for the number of puffs the doctor prescribed. 6. Holding the head too far forward or backward FIX IT: The head needs to be in a normal position, not too far back or too far forward, to help make a direct path for the medicine to reach the airways. 7. Tongue or teeth in the way of spacer/inhaler opening FIX IT: Put the mouthpiece of the spacer/inhaler in the mouth above the tongue, under the top teeth. 8. Mouth not tight enough around spacer/inhaler FIX IT: Close the lips around the mouthpiece of the spacer or inhaler so air does not escape. 9. Directing spacer/inhaler at tongue or roof of mouth FIX IT: Aim the spacer/inhaler at the back of the throat, so the medicine reaches the lungs. 10. Inhaling medicine too fast FIX IT: Inhale slowly. A whistle sound made when using a spacer means the inhalation is too fast. These tips are not applicable to breath-activated and powder inhalers. Reminders Follow instructions for using your inhaler. Gargle and spit after inhaling a steroid. Show your inhaler technique to your provider. Clean the inhaler and spacer according to instructions.
