June 2007
Advair is the first metered-dose inhaler (MDI) with a dose counter in Canada.
It's hard to tell when an MDI is empty.
About 74% of patients say they don't know how many doses are left in their MDI. And up to 25% of asthma patients find their salbutamol inhalers empty during an asthma attack...and some have to call 911 for help.
