Budesonide and Formoterol Overview

Reviewed: February 3, 2015

Budesonide/formoterol is a prescription medication used to treat asthma and COPD. It is a combination medication that contains an inhaled corticosteroid, budesonide, to help decrease inflammation in the lungs, and a long-acting beta2-agonist medicine (LABA), formoterol. LABA medicines, like formoterol, help the muscles around the airways in the lungs stay relaxed to prevent asthma symptoms, such as wheezing and shortness of breath.

Budesonide/formoterol comes in a metered-dose inhaler. It is used twice daily.

Common side effects include throat irritation or pain, headaches, and colds.

Serious side effects have been reported with budesonide/formoterol including the following:

  • People with asthma who take LABA medicines such as formoterol have an increased risk of death from asthma problems.  It is not known whether budesonide reduces the risk of death from asthma problems seen with formoterol.
  • Call your healthcare provider if breathing problems worsen over time while using budesonide/formoterol.  You may need different treatment.

  • When your asthma is well controlled, your healthcare provider may tell you to stop taking budesonide/formoterol.  Your healthcare provider will decide if you can stop budesonide/formoterol without loss of asthma control.  Your healthcare provider may prescribe a different long-term asthma-control medicine for you, such as an inhale corticosteroid.
  • Children and adolescents who take LABA medicines may have an increased risk of being hospitalized for asthma problems.

  • to treat sudden severe symptoms of asthma or COPD
  • if you are allergic to any of the ingredients in budesonide/formoterol

Budesonide/formoterol falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Budesonide and Formoterol FDA Warning


Long-acting beta2-adrenergic agonists (LABA), such as formoterol one of the active ingredients in budesonide/formoterol, increase the risk of asthma-related death. Data from a large placebo-controlled U.S. study that compared the safety of another long-acting beta2-adrenergic agonist (salmeterol) or placebo added to usual asthma therapy showed an increase in asthma-related deaths in patients receiving salmeterol. This finding with salmeterol is considered a class effect of the LABA, including formoterol. Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA. Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients. Therefore, when treating patients with asthma, budesonide/formoterol should only be used for patients not adequately controlled on a long-term asthma control medication, such as an inhaled corticosteroid or whose disease severity clearly warrants initiation of treatment with both an inhaled corticosteroid and LABA. Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (e.g., discontinue budesonide/formoterol) if possible without loss of asthma control and maintain the patient on a long-term asthma control medication, such as an inhaled corticosteroid. Do not use budesonide/formoterol for patients whose asthma is adequately controlled on low or medium dose inhaled corticosteroids.
