How to Use the Metered Dose Inhaler with a Spacer -




Preparing the Inhaler

  • Put the inhaler together (as needed). Most do not require assembly.
  • Inspect the spacer for foreign objects, if there is a valve, make sure it is intact and not damaged, torn, or missing.
  • Remove the cap from the mouthpiece. 
  • Attach the inhaler to the spacer.


Using a Metered Dose Inhaler with a Spacer 

  • Shake the inhaler for several seconds. (*specific controller medications do not require shaking)
  • Prime the inhaler as needed - will vary depending on brand - "priming" is done to mix the medication with the propellant, to help prevent medication build-up and blockages, and ensure that the inhaler works properly by releasing a test spray into the air prior to use. Refer to the manufacturer's insert included with the MDI.
  • Hold the inhaler upright with your index finger on top and thumb on the bottom, support the spacer with your other hand. 
  • Exhale fully and gently through your mouth.
  • Position the spacer comfortably in your mouth, with your lips and teeth around the mouth piece.
  • Press down on the inhaler. 
  • Inhale slowly and deeply for about 3 to 5 seconds as the medicine moves from the  spacer into your lungs. 
  • Close your mouth, hold your breath for at least 10 seconds; then exhale. 
  • Repeat dose(s) as ordered. Be sure to shake the inhaler before each puff or pressing down on the inhaler.
  • Wait 30 – 60 seconds between doses  - waiting between puffs allows the medication you breathed in to take effect by beginning to open your airways and give relief. With your lungs more relaxed and open, you will be able to breathe in the next puff of medication deeper to provide better relief of symptoms.
  • Wait at least 10 minutes when using two or more types of inhalers (such as bronchodilators, anticholinergics, corticosteroids). Typically,  FIRST use your bronchodilator (such as albuterol or xopenex) to open up or dilate the lungs, then use other long acting controller medications or combined inhaled medications such as inhaled steroid or non-steroid inhaled medications (such as  pulmicort, flovent, advair, symbicort, atrovent, or intal, etc.).
