Using a Metered-Dose Inhaler for Teens: Care Instructions

Skip to the navigation

Your Care Instructions

A metered-dose inhaler lets you breathe medicine into your lungs quickly. Inhaled medicine works faster than the same medicine in a pill. An inhaler lets you take less medicine than you would need if you took it as a pill.

"Metered-dose" means that the inhaler gives a measured amount of medicine each time you use it. This type of inhaler delivers medicine in the form of a liquid mist.

Your doctor may want you to use a spacer with your inhaler. A spacer is a chamber that you attach to the inhaler. The chamber holds the medicine before you inhale it. That way, you can inhale the medicine in as many breaths as you need. Doctors recommend using a spacer with most metered-dose inhalers, especially those with corticosteroid medicines.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

To get started

  • Talk with your doctor, respiratory therapist, or pharmacist to be sure you are using your inhaler the right way. It might help if you practise using it in front of a mirror. Use the inhaler exactly as prescribed.
  • Check that you have the correct medicine. If you use several inhalers, put a label on each one so that you know which one to use at the right time.
  • Keep track of how much medicine is in the inhaler. Check the label to see how many doses are in it. If you know how many puffs you can take, you can replace the inhaler before you run out. Your doctor or pharmacist can teach you how to keep track of how much medicine is left.
  • Use a spacer if you have problems pressing the inhaler and breathing in at the same time. You also may need a spacer if you are using corticosteroid medicines.
  • If you are using corticosteroids, gargle and rinse out your mouth with water after use. Do not swallow the water. Swallowing the water will increase the chance that the medicine will get into your bloodstream. This may make it more likely that you will have side effects from the medicine.

To use a spacer with an inhaler

  1. Shake the inhaler, and remove the inhaler cap. Place the mouthpiece of the inhaler into the spacer.
  2. Remove the cap from the spacer.
  3. Hold the inhaler upright with the mouthpiece at the bottom.
  4. Tilt your head back a little, and breathe out slowly and completely.
  5. Place the spacer's mouthpiece in your mouth.
  6. Press down on the inhaler to spray one puff of medicine into the spacer. Then start breathing in slowly. Wait to inhale until after you have pressed down on the inhaler.
  7. Hold your breath for 10 seconds. This will let the medicine settle in your lungs.
  8. If you need to take a second dose, wait 30 to 60 seconds. This lets the inhaler valve refill.

To use an inhaler without a spacer

  1. Shake the inhaler as directed. Remove the cap.
  2. Hold the inhaler upright with the mouthpiece at the bottom.
  3. Tilt your head back a little, and breathe out slowly and completely.
  4. Position the inhaler in one of two ways:
    • You can place the inhaler in your mouth. This is easier for most people. It also lowers the risk that any of the medicine will get into your eyes.
    • Or you can place the inhaler 2.5 to 5 centimetres in front of your open mouth. Don't close your lips over it. Try to open your mouth as wide as you can. Placing the inhaler in front of your open mouth may be better for getting the medicine into your lungs. But some people may find this too hard to do.
  5. Start taking slow, even breaths through your mouth. Press down on the inhaler one time. Then inhale fully.
  6. Hold your breath for 10 seconds. This will let the medicine settle in your lungs.
  7. If you need to take a second dose, wait 30 to 60 seconds to let the inhaler valve refill.
