Clinical Trials on Proair HFA and Treatment Tips

Effects of Proair HFA

During previous clinical studies, Proair HFA started working within 8.2 minutes, and the effects lasted for three hours, on average. Studies have also shown that taking the medication 30 minutes before exercise can help in preventing exercise-induced asthma symptoms.
 

When and How to Take Proair HFA

Following are some general considerations for when and how to take Proair HFA:
 
  • The medication comes in a metered-dose inhaler (called an "MDI").
     
  • Some people take Proair HFA only when they need it (during an asthma attack), while others take it regularly to help prevent attacks.
     
  • You should "prime" each inhaler before your first use of it, or if you have not used it for two weeks or more. To prime the inhaler, spray it into the air three times.

 

  • Shake your Proair HFA asthma inhaler gently before each use.
     
  • Wait at least one minute in between inhalations.
     
  • It is important that you learn exactly how to use your inhaler. It may be difficult at first and may require practice.
     
  • The spray should be inhaled into the lungs, not sprayed onto the back of the throat and swallowed. To accomplish this, you will need to breathe in while spraying the inhaler.
     
  • Most people put the mouthpiece of the inhaler directly into their mouths. However, many healthcare professionals now recommend placing the inhaler an inch or two away from the mouth. Talk with your healthcare provider about the best way for you to use it.
     
  • Each inhaler contains 200 sprays. Try to keep track of approximately how many sprays you have used so that you will know when to replace the inhaler. Do not place the inhaler in water to see if it is empty (even though doing so was recommended in the past).

 

  • Make sure to wash the mouthpiece with warm running water at least once a week. 

 

  • For Proair HFA to work properly, it must be taken as prescribed. The medication will not work if you stop taking it.
