How to use a metered dose inhaler — Each inhaler manufacturer has specific instructions for using their inhaler; the following are general instructions.
When using a metered dose inhaler FOR THE FIRST TIME (with or without a spacer), prepare the inhaler first:
●Shake the inhaler for five seconds.
●Prime the inhaler by pressing down the canister with the index finger to release the medication. Hold the inhaler away from your face to prevent medication from getting into your eyes. Press the canister down again 3 times.
After an inhaler is used for the first time, it does not need to be primed again unless you do not use it for two weeks or more.
Instructions for using the inhaler are available in the Table (table 1 and table 2).

●Take a slow, deep breath at the same time you press down on the medication caniste
