Symbicort is a type of âmaintenanceâ therapy for COPD. This means that it should be used every day to help manage and reduce the symptoms that a COPD patient has all or most of the time. The medicine is not used for treating COPD flare-ups or sudden symptoms.
The key difference is that symbicort also contains a long acting form of albuterol called formeterol. This long acting medicine has been shown in some studies to increase the risk of asthma related deaths and is only recommended when other forms of treatment are failing. http://www.rxlist.com/flovent-drug.htm.
