Info on Ventolin's Effects and When and How to Take It


In previous clinical studies, Ventolin was shown to work just as well as the older albuterol inhalers (which are not environmentally friendly). Ventolin starts working within six minutes, and the effects of the drug last for approximately four hours on average. Studies have also shown that taking Ventolin 30 minutes before exercise can help prevent exercise-induced asthma symptoms.

When and How to Take Ventolin

Following are some general considerations for when and how to take Ventolin:
  • It comes in a metered-dose inhaler (called an "MDI").
  • Some people take it only when they need it (during an asthma attack), while others take it regularly to help prevent attacks.
  • You should "test spray" each Ventolin inhaler before your first use of it, or if you have not used it for a long period of time. To test spray the inhaler, spray it into the air by pressing on the top of the canister.
  • Shake your inhaler gently before each use.
  • Wait at least one minute in between inhalations.
  • It is important to learn exactly how to use your Ventolin inhaler. It may be difficult at first and may require some 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 the inhaler.
  • Each inhaler contains 200 sprays. Ventolin is the only inhaler with a built-in dose counter that keeps track of how many inhalations have been dispensed. It starts at "200" and counts down to "0," at which point it should no longer be used.
  • For Ventolin to work properly, it must be taken as prescribed. It will not work if you stop taking it.
