Formoterol relaxes the airway muscle for about 12 hours. It starts working within minutes but must always be used together with an inhaled steroid in asthma.
Budesonide reduces the inflammation and swelling in the airway lining. Taken regularly it prevents asthma attacks; it does nothing for an attack already under way.
Most side effects are mild and settle as your body adjusts. Tell your doctor if any of them persist or trouble you.
