Hold the inhaler a few inches in front of your mouth, at the opening of your mouth if you are using a spacer, or in your mouth, depending on the instructions from your physician
Slowly breathe in (inhale) and squeeze down on the canister (if you are using a holding chamber, press down on the chamber and then inhale slowly)
Continue to breathe in (inhale) slowly
At the end of inspiration attempt to hold your breath to the count of one to ten if possible
Wait about 15 to 30 seconds before the next inhalation if you are using a short-acting beta agonist (This is not necessary if you are inhaling a medication other than a short-acting beta agonist)
Note: During the above procedure, coughing may occur and not allow for a complete slow inhalation and the inhalation will be cut off abruptly. This is not a problem as whatever material has been inhaled and absorbed will usually help improve the severity of asthma.
If the coughing problem persists and the severity of asthma does not improve, another form of treatment must be added or used separately.
