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 other component of Symbicort is budesonide, an asthma medication that belongs to a group of drugs called inhaled corticosteroids, or steroids for short. Inhaled steroids go directly into the lungs and help to decrease the inflammation of airways that makes asthma attacks more likely.Because Symbicort does not work quickly, it should not be used for treating an asthma attack. Rather, it is used twice a day in order to prevent them.nhaled steroids go directly into the lungs and help to decrease the inflammation of airways that makes asthma attacks more likely.
