Proper Use

  • See instruction for proper use. Use every day for best results.
  • Pulmicort Flexhaler: Prepare inhaler before first use only. Prepare the inhaler by holding the inhaler upright and twisting the brown grip as far as it will go in one direction then fully back in the other direction until it stops. It does not matter which direction you turn the brown base. You will hear a “click” during one of the twisting movements.

    To load a dose, hold inhaler in upright position (mouthpiece up) and twist the brown base as far as it will go in one direction, then all the way back the other direction. You will hear a click when the dose is loaded. Do not shake the inhaler. Place mouthpiece between lips and inhale forcefully and deeply. Do not exhale through inhaler; do not use a spacer. Dose indicator does not move with every dose, usually only after 5 doses. Discard when dose indicator reads "0". Rinse mouth with water after each use to reduce incidence of mouth or throat infection.
  • Suspension for nebulization: Shake well before using. Use Pulmicort Respules with jet nebulizer connected to an air compressor; administer with mouthpiece or facemask. Do not use ultrasonic nebulizer. Do not mix with other medications in nebulizer. Rinse mouth following treatments to decrease risk of mouth or throat infection (wash face if using face mask). For information on the correct use of nebulizers, visit our nebulizer page.
