Metered-dose Inhalers (MDIs)

Most of these devices, which deliver medication to your lungs as a spray, require a prescription from your doctor. The medication in a metered-dose inhaler that can be bought without a prescription, such as Primatine Mist™, is adrenaline, a short-acting drug which may be dangerous for persons with heart disease. It is inadequate to treat COPD.

In order to get the maximum benefit from the medication, it is important that the inhaler be used properly. Here are some helpful tips for using a metered-dose inhaler:

1.	Remove the cap from the mouthpiece.
2.	Shake the inhaler for a few seconds. Breathe out comfortably––not all the way out.
3.	Hold the inhaler upright and place it in front of your mouth. Keep your mouth slightly open. Breathe in deeply and at the same time press the inhaler between your thumb and index finger. This will force the medication from the inhaler into your throat and lungs.
4.	Remove the inhaler and hold your breath for a few seconds; then resume normal breathing. Wait at least two minutes before repeating the process. (Most inhaler medications specify that two puffs should be taken. Wait at least two minutes between each puff.)

Remember, a double pump of the inhaler before one breath delivers less medicine to the lungs than a puff for each breath you take. Use one pump of the inhaler for the number of puffs your doctor prescribes. Do not exceed the dose prescribed by your doctor. If you continue to have difficulty breathing, contact your doctor immediately.

If you have trouble coordinating your breathing with pressing the inhaler, ask your doctor if using a spacer or extender will make it easier for you to inhale the mist from the MDI.
