Key product details

Medication Class & Use

  • Corticosteroid (maintenance inhaler or steroid inhaler): Works by decreasing inflammation, swelling, and mucus production over time. This medicine will help open airways and make breathing easier if used every day, even when feeling well.


  • Usual adult asthma starting dose: 360 mcg twice daily (max 720 mcg twice daily)
  • Pedatric dosing: 180 mg twice daily.
  • Available strengths: 90 mcg/actuation; 180 mcg/actuation.
  • Inhalers contain either 60 or 120 inhalations per device.


Priming: Prime 1 time before first use only:

  1. Hold upright (brown grip on bottom). Turn the white cover and lift it off.
  2. Hold the middle of the inhaler (not the mouthpiece) in one hand and turn the brown grip as far as it will go in one direction. Repeat in the opposite direction (you will hear a click during one of the turns).
  3. Repeat step 2 and your first dose is ready to be loaded. There is no need to prime the inhaler again.


  • Dose indicator is marked at intervals of 10 doses. Inhaler is empty when dose counter reads 0 in the middle of the window.
  • The inhaler will only release one dose of medication at a time no matter how many times you click the brown grip. However, the dose counter will continue to advance with each click, so the inhaler may actually contain additional doses when the dose counter reads 0.


  • KEEP DRY. Clean outside the mouthpiece once weekly with a dry tissue.
