How to Use a Spacer for Asthma Medicines

A spacer is a tube that attaches to an asthma inhaler (also called a metered-dose inhaler or MDI). It holds the medicine so people can breathe the medicine in slowly and deeply, either through the mouthpiece or a mask. This helps more medicine reach the lungs.

Instructions

How to Use a Spacer

  1. Check the spacer for any cracks, damage, dirt, or particles. If it's cracked or damaged, don't use it. If it has dirt or particles in it, clean it according to the manufacturer's instructions.
  2. Remove the cap from the inhaler.
  3. Connect the spacer to the inhaler.
  4. Shake the inhaler before each use and in between each inhalation. It's OK to shake it when it's attached to the spacer.
  5. Stand or sit up straight.
  6. Breathe out slowly and fully to empty your lungs. Make sure to face away from the spacer so you don't breathe into it.
  7. If using the mouthpiece:
    • Close your lips around the mouthpiece, press the inhaler to release the medicine into the spacer, and take a slow, deep breath in through your mouth.
    • Remove the spacer from your mouth.
    • Hold your breath for about 10 seconds to allow the medicine to settle in your lungs, then breathe out through your mouth.
  8. If using a mask:
    • Press the mask firmly on your skin, covering the nose and mouth.
    • Press the inhaler to release the medicine into the chamber.
    • Take 5–6 slow, deep breaths in and out through your mouth before removing the mask.
  9. Shake the inhaler and repeat after about 30 to 60 seconds if your healthcare provider prescribed more than one inhalation (puff) of medicine.

Reminders

  • If the spacer makes a noise (such as a squeak or a honk), you are breathing in too hard or too quickly. Breathe in a bit more slowly and softly.
  • If your medicine is an inhaled steroid, rinse out your mouth with water after using the spacer and inhaler. If you are unsure if your medicine is an inhaled steroid, check with your healthcare provider.
  • Clean the spacer according to the manufacturer's instructions when it looks cloudy and at least once a week (when using every day). Be sure the spacer is completely dry before using it.
  • Throw away the inhaler as recommended by the manufacturer or if you notice any cracks or problems.
