Once you begin using the Diskus Inhaler, mark your calendar for the next refill date. The refill date will depend on how often you use your inhaler.

If you take just one dose per day, you can use your Diskus inhaler for up to six weeks. Mark your calendar for a refill in about five weeks.

If you take two doses per day, your Diskus inhaler will be empty in 30 days. Mark your calendar for a refill in about 25 days.
