The pulmicort flexhaler is a dry powder steroid inhaler that delivers asthma control medicine. Open the flexhaler by twisting the white cover and lift off. If the flexhaler is new, prime it by twisting and clicking it twice. Hold upright and twist the grip as far to the right as it will go. Twist back again to the left until you hear it click. This loads the dose of medicine. Do not shake the flexhaler. Hold the flexhaler up and straight by the base. Be careful not to cover the air vents. Place the teeth and lips tightly on the mouthpiece and inhale quickly. Remove the inhaler from the mouth and exhale. Repeat these steps for each puff ordered by your doctor or nurse. Place the cover back on the flexhaler and twist shut. After each use, rinse the mouth. Store in a dry and cool place. A window on the flexhaler will show how many doses are in the pulmicort flexhaler. Keep track of the number of doses available and fill the prescription before your pulmicort flexhaler is empty.
