budesonide and formoterol is not for use in treating an asthma or bronchospasm attack.

Follow all directions on your prescription label and read all medication guides. Use the medicine exactly as directed. Using too much of this medicine can cause life-threatening side effects.

If you also use an oral steroid medication, you should not stop using it suddenly. Follow your doctor's instructions about tapering your dose.

Budesonide and formoterol is not a rescue medicine for asthma or bronchospasm attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.
