When you first start using a new inhaler, figure out how long the canister will last and mark that date on a calendar or on the canister.

Make sure you get your refill at least one week before the date you marked.

Remember, controller medicines are used daily. For rescue medicines, you will need to keep track of each time you use the inhaler. (For example, make a mark on the calendar for each puff and total them up, so you know how many puffs are remaining.)

DON'T BE CAUGHT WITH AN EMPTY INHALER!
