  • Asmanex HFA: Shake well prior to each inhalation. Prepare inhaler before first use by releasing 4 test sprays into the air, away from the face, shaking well before each spray. If the inhaler has not been used for more than 5 days, prepare the inhaler again with 4 test sprays. Rinse mouth with water without swallowing. For proper inhaler technique visit our inhaler page.
  • Asmanex Twisthaler: After removing from foil pouch, record the date of opening on the cap label. Remove the inhaler cap while holding inhaler upright. Exhale fully before bringing the Twisthaler up to the mouth. Place between lips and inhale quickly and deeply. Remove inhaler and hold breath for 10 seconds if possible. Do not breathe out through the inhaler. Wipe mouthpiece dry, replace cap, and rotate until you hear a "click". Rinse mouth after use to reduce risk of mouth or throat infection.
