Self-management

Using a nebulizer: To take this drug, you need to use a nebulizer. A nebulizer is a machine that turns the drug into a mist that you inhale. Not all nebulizers work in the same way. Your doctor will tell you which type to use and will show you how to use it.

These are the basic steps to set up and use your nebulizer:

  • Connect the hose to an air compressor.
  • Fill the medication cup with your dose. To avoid spills, close the medicationcup tightly and always hold the mouthpiece straight up and down.
  • Attach the hose and mouthpiece to the medicationcup.
  • Place the mouthpiece in your mouth. Hold your lips firmly around the mouthpiece so that all of the medicationgoes into your lungs.
  • Breathe through your mouth until all the medicationis used. This can take 10–15 minutes or more. If needed, use a nose clip so that you breathe only through your mouth. Small children usually do better if they wear a mask.
  • Turn off the machine when done.

Wash the medicationcup and mouthpiece with water and air dry until your next treatment. It’s important to keep your nebulizer clean so that it works properly.

Clinical monitoring

Your doctor will check your lung function. Your doctor will monitor your lung function with pulmonary function tests. These are breathing tests.
