Instructions for use

  1. Wash and dry your hands well.
  2. Hold the inhaler straight up with the base (gray or pink portion) on the bottom.
  3. Remove the cap while it is in the upright position to make sure the right dose is loaded.
  4. Hold the base and twist the cap in a counter-clockwise direction to remove it.
  5. As the cap is lifted off, the dose counter on the base will count down by 1. This action also loads the dose, so do not shake the inhaler once it’s open.

  7. Exhale out through mouth away from the inhaler.
  8. Place the mouthpiece into your mouth, while holding the inhaler level with the floor. Be careful not to cover the ventilation holes.
  9. Close your lips tightly around the mouthpiece and take a fast, deep breath.
  10. Remove the mouthpiece from your mouth and hold your breath for 10 seconds or as long as possible.
  11. Exhale through your mouth slowly away from the inhaler.
  12. Immediately replace the cap, turn in a clockwise direction, while gently pressing down until you hear a click.
