Budesonide is used to help prevent the symptoms of asthma. When used regularly every day, inhaled budesonide decreases the number and severity of asthma attacks. However, it will not relieve an asthma attack that has already started.

Budesonide is a corticosteroid or steroid (cortisone-like medicine). It works by preventing inflammation (swelling) in the lungs, which makes the asthma attack less severe. Inhaled budesonide may be used with other asthma medicines such as bronchodilators, which are also used to open up narrowed breathing passages in the lungs.

This medicine is available only with your doctor's prescription.

Zyflo CR is a leukotriene (loo-koe-TRY-een) inhibitor. Leukotrienes are chemicals your body releases when you breathe in an allergen (such as pollen). These chemicals cause swelling in your lungs and tightening of the muscles around your airways, which can result in asthma symptoms.

Zyflo CR is used to prevent asthma attacks in adults and children as young as 12 years old.

Zyflo CR may also be used for purposes not listed in this medication guide.
