Shake the inhaler after removing the cap and apply the spacer.

Breathe out for 1 or 2 seconds.

Put the mouthpiece of the spacer between your teeth and close your lips tightly around the mouthpiece. If you are using a mask attached to the spacer, place the mask completely over your nose and mouth. Start to breathe in slowly, like sipping hot soup.

While starting to breathe in, press the top of the inhaler.

Breathe in slowly until your lungs are full. (This should take about 5 or 6 seconds.)

Hold your breath for 10 seconds (or as long as you can).

Breathe out and, if a second dose is required, repeat the procedure after 1 minute.
