What is beclometasone?

  • Beclometasone is used to prevent asthma.
  • It works by preventing the swelling and irritation in the walls of the small air passages in the lungs.
  • It belongs to a group of medicines known as inhaled corticosteroids. It is also called a preventer (because when used every day it prevents asthma attacks).


  • The dose of beclometasone varies depending on the strength of your inhaler — the usual dose is 1 or 2 puffs  inhaled two times a day.
  • Beclometasone does not give immediate relief from an asthma attack and may take up to a week to start to work.
  • Since asthma is a long-term condition, prevention with beclometasone is ongoing and it will need to be used  every day for months or years.

How to use beclometasone inhaler (puffer)

  • To get the most benefit from the medication, it is important to use the correct technique when using an inhaler.

    • Remove the cap off the inhaler mouthpiece.
    • Hold the inhaler upright, with your thumb on the base and your first finger on the top of the can. Shake the inhaler vigorously up and down.
    • Breathe out normally as far as you comfortably can. Then hold the mouthpiece firmly between your lips. Breathe in slowly and deeply.
    • As you first start to breathe in press the aerosol can with your first finger to spray the aerosol and release the medicine. Continue to breathe in slowly and deeply.
    • Take the inhaler out of your mouth and hold your breath for 10 seconds, or for as long as you comfortably can. Breathe out slowly.
