Breathing Problems: Using a Metered-Dose Inhaler

Overview

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 allows you to 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. A metered-dose inhaler gives 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. This is even more important when using corticosteroid medicines.

How to use the inhaler

Getting started

To get started:

Talk with your doctor to be sure you are using your inhaler the right way. It might help if you practice using it in front of a mirror. Use the inhaler exactly as prescribed.
Check that you have the correct medicine. If you use more than one inhaler, put a label on each one. This will let 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 the container. If you know how many puffs you can take, you can replace the inhaler before you run out. Ask your health care provider how you can keep track of how much medicine is left.
Talk to your doctor about using a spacer with your inhaler. Spacers make it easier to get the medicine into your lungs. You may need a spacer if you are using corticosteroid medicines. A spacer can also help if you have problems pressing the inhaler and breathing in at the same time.
If you are using a corticosteroid inhaler, 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.
