Metered-Dose Inhaler: How to Use it
How can I keep track of how much
medicine I've used?
It's important to keep track of how much
medicine you've used so you can plan ahead and replace your inhaler before you
run out of medicine. One way to do this is to write a refill date on the
canister itself. To figure out when you'll need to get a refill, start with a
brand new inhaler. Divide the number of puffs in the canister--the canister will
usually have this number printed on it--by the number of puffs you take each
day. The number you get will be the number of days the canister should last.
(For example, if you take 4 puffs each day from a 200-puff canister, you will
need to have a new canister every 50 days.) Using a calendar, count forward that
many days to see when your medicine will run out. So you won't run out of the
medicine that you use every day, choose a day 1 or 2 days before this date to
have your prescription refilled. Using a permanent marker, write the refill date
on the canister.
If you use your inhaler for rescue medicine, you
probably won't be using it regularly enough for this method to work. In that
case, ask your doctor if he or she will write a prescription for two inhalers at
a time. Then get your prescription filled when the first inhaler is empty. This
way, you'll always have enough rescue medicine on hand when you need it most.

A is the best way, but C is okay for people who are unable to use A or B.
Spacers are useful for all
patients. (See picture B.) They are very helpful for young children and older
adults. They are also helpful to use with inhaled steroid medicines.
- Press down on the inhaler to release the medicine
as you start to breathe in slowly.
- Breathe in slowly for 3 to 5 seconds.
- Hold your breath for 10 seconds to allow medicine
to go deeply into your lungs.
- Repeat puffs as directed. Wait 1 minute between
puffs to allow the second puff to get into the lungs better.
NOTE: Inhaled dry powder
capsules are used differently. To use a dry powder inhaler, close your mouth
tightly around the mouthpiece of the inhaler and breathe in quickly.
