Patient Education

Formoterol Oral Inhalation


Formoterol oral inhalation is used to control wheezing, shortness of breath, and chest tightness caused by chronic obstructive pulmonary disease (COPD; a group of lung diseases that includes chronic bronchitis and emphysema). Formoterol is in a class of medications called long-acting beta agonists (LABAs). It works by relaxing and opening air passages in the lungs, making it easier to breathe.
