How to Use a Flexhaler Asthma Inhaler

To load a dose of medicine:

Twist the cover and lift it off.

Hold the Flexhaler with the mouthpiece pointing up to load the medicine.

Twist the brown grip to the right as far as it will go and then back to the left. You will hear a click. The device is now ready to use.

Breathing in the medicine:

Turn your head away from the Flexhaler. Gently breathe out as much air as you can.

Seal your lips around the Flexhaler mouthpiece. Be sure to hold the inhaler in a horizontal position.

Breathe in deep and steady through your mouth. Remove the Flexhaler from your mouth

Hold your breath for 5 to 10 seconds with your mouth closed. Then resume normal breathing. Rinse your mouth with water and spit it out.

If more than one dose is prescribed, repeat these steps.

Place the cover on the Flexhaler and twist it completely closed.
