Patient Education

Budesonide Oral Inhalation


Budesonide is used to prevent difficulty breathing, chest tightness, wheezing, and coughing caused by asthma. Budesonide powder for oral inhalation (Pulmicort Flexhaler) is used in adults and children 6 years of age and older. Budesonide suspension (liquid) for oral inhalation (Pulmicort Respules) is used in children 12 months to 8 years of age. Budesonide belongs to a class of medications called corticosteroids. It works by decreasing swelling and irritation in the airways to allow for easier breathing.

Steroids


You may have heard of anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands make to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.

You may need to take corticosteroids to treat

  • Arthritis
  • Asthma
  • Autoimmune diseases such as lupus and multiple sclerosis
  • Skin conditions such as eczema and rashes
  • Some kinds of cancer

Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a time as possible.
