Clinical Trials on Flovent and How to Use Your Inhaler

Effects of Flovent

In clinical studies, people taking Flovent had improvements in breathing and asthma symptoms, compared to those not taking it. In these studies, people already taking oral steroids for asthma were able to decrease or eliminate their oral steroid when they began taking Flovent. However, this medication is not an asthma cure.

How to Use Flovent HFA

Some general considerations for when and how to take Flovent HFA include the following:
  • The medication comes in a metered-dose inhaler (called an "MDI"). Flovent HFA is taken twice a day, every day. It is used to prevent asthma attacks, not to treat them.


  • You should "test spray" an inhaler before your first use of it, or if you have not used it for a long time. To test spray the inhaler, spray it into the air by pressing on the top of the canister.
  • Shake your asthma inhaler gently before each use. Wait at least one minute in between inhalations. Rinse out your mouth (without swallowing) after each dose, in order to prevent thrush.


  • 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. It is important to learn exactly how to use your inhaler. It may be difficult at first and may require practice. 


  • 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 the inhaler.
  • Each inhaler contains 120 sprays and has a built-in dose counter that keeps track of how many inhalations have been dispensed. It starts at "120" and counts down to "000," at which point it should no longer be used.
  • For Flovent HFA to work properly, it must be taken as prescribed. The medication will not work if you stop taking it.
