Formoterol is used as a long-term (maintenance) treatment
to prevent or decrease breathing problems caused by ongoing lung diseases
(chronic obstructive pulmonary disease-COPD, including chronic bronchitis and
emphysema). Formoterol belongs to the class of drugs known as long-acting
inhaled beta-agonists. It works by opening air passages in the lungs to make
breathing easier. This effect helps to reduce wheezing, coughing, and shortness
of breath.This medication does not work immediately and should not
be used for sudden attacks of breathing trouble. Your doctor must prescribe a
quick-relief inhaler (e.g., albuterol, also called salbutamol in some
countries) for sudden shortness of breath while you are using formoterol. You
should always have a quick-relief inhaler with you.Formoterol is usually used with other medications such as
corticosteroids (inhaled or taken by mouth). However, it should not be used
with other long-acting inhaled beta agonists (e.g., salmeterol) because doing
so may increase your risk for side effects.
