Using Your Asthma Inhaler Properly

There are two main types of inhalers. The metered dose inhaler uses a chemical propellant, albuterol, to carry a dose of medication into an asthmatic's lungs. These inhalers typically are used to deliver "rescue" medications, which open bronchial airways to arrest the symptoms of a full-blown asthma attack. Two examples of albuterol medications are Proventil HFA and Ventolin HFA. It's important to take the time to read the instructions very carefully and to be sure to have their use demonstrated by your allergist or nurse.

The other type of inhaler, the dry powder inhaler, is used for longer-term treatment. It requires no propellant as the drug is sucked into the lungs by a quick, strong inhalation. The medication reduces asthma symptoms, such as shortness of breath, and improves airflow to the lungs

Commonly used examples of a DPI are the Advair Diskus or Symbicort. An asthma patient puts the mouthpiece of the inhaler into his mouth and takes a deep inhalation, holding his breath for 5-10 seconds. The dose that can be delivered is typically less than a few tens of milligrams in a single breath since larger powder doses may aggravate coughing. Once again it is important to have their use demonstrated by your allergist or nurse.

Also, at each visit, be sure to ask your doctor or nurse to:

• Check that you are using your inhaler properly
• Tell you where to find the expiration date on your inhaler
• Show you how to check if your inhaler is empty or nearly empty
• Discuss any unwanted effects from your medication
• Explain how to clean your inhaler and spacer (if you have one).
