Budesonide/formoterol, sold under the brand name Symbicort among others, is a fixed-dose combination medication used in the management of asthma or chronic obstructive pulmonary disease (COPD).[2] It contains budesonide, a steroid; and formoterol, a long-acting β2-agonist (LABA).[2] The product monograph does not support its use for sudden worsening or treatment of active bronchospasm.[2] However, a 2020 review of the literature does support such use.[6] It is used by breathing in the medication.[2]
Common (≥1/100 to <1/10) side effects include candidiasis, headache, tremor, palpitations, throat irritation, coughing, and dysphonia.[7] Pneumonia is a common side effect in people with COPD, and other, less common side effects have been documented.[2][3] There were concerns that the LABA component increases the risk of death in children with asthma, however these concerns were removed in 2017.[8] Therefore, this combination is only recommended in those who are not controlled on an inhaled steroid alone.[2] There is tentative evidence that typical doses of inhaled steroids and LABAs are safe in pregnancy.[9] Both formoterol and budesonide are excreted in breast-milk.[1]
Budesonide/formoterol was approved for medical use in the United States in 2006.[2][10] It is on the World Health Organization's List of Essential Medicines.[11][12] It is available as a generic medication.[13] In 2022, it was the 83rd most commonly prescribed medication in the United States, with more than 8 million prescriptions.[14][15]

Medical uses
Summarize
Perspective
Budesonide/formoterol is indicated for the treatment of asthma and for the maintenance treatment of airflow obstruction and reducing exacerbations in people with chronic obstructive pulmonary disease.[2][4][5]
Maintenance
Budesonide/formoterol has shown efficacy to prevent asthma attacks.[6] It is unclear if the efficacy of budesonide/formoterol differs from that of fluticasone and salmeterol in chronic asthma.[16]
Exacerbation
The combination is approved in the United States only as a maintenance medication in asthma and chronic obstructive pulmonary disease (COPD).[2] However, a 2020 review of the literature does support use as needed during acute worsening in those with mild disease, and as maintenance followed by extra doses during worsening.[6]
Use for both maintenance and as-needed treatment is also known as single maintenance and reliever therapy (SMART) and is a well-established treatment.[17][18] It has been shown to, 1) reduce asthma exacerbations that require oral corticosteroids, 2) reduce hospital visits better than maintenance on inhaled corticosteroids alone at a higher dose, or 3) inhaled corticosteroid at the same or higher dose together with a long-acting bronchodilator (LABA), with a short-acting bronchodilator (SABA) as a reliever.[17][18]
