You should follow the instructions packaged with your medication.  The following is one way to use your inhaler.

To use your MDI without a spacer:

1. Shake the inhaler well before use (three or four shakes)
2. Remove the cap
3. Breathe out, away from your inhaler
4. Bring the inhaler to your mouth. Place it in your mouth between your teeth and close your mouth around it.
5. Start to breathe in slowly. Press the top of your inhaler once and keep breathing in slowly until you've taken a full breath
6. Remove the inhaler from your mouth, and hold your breath for about ten seconds, then breathe out

If you need a second puff, wait 30 seconds, shake your inhaler again, and repeat steps 3-6.

Always write down the number of puffs you've taken so that you can anticipate when you need to refill your prescription.

Store all MDI’s at room temperature.
