Additional Information

Why is this medication prescribed

Formoterol is used to treat wheezing, shortness of breath, and troubled breathing caused by asthma and chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis, emphysema, and other lung diseases. It also is used to prevent breathing difficulties (bronchospasm) during exercise. Formoterol is in a class of medications called long-acting beta agonists. It works by relaxing and opening air passages in the lungs, making it easier to breathe.

Other uses for this medicine

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What other information should I know

Keep all appointments with your doctor.

If your asthma symptoms become worse, if formoterol inhalation becomes less effective, or if you need more doses than usual of a short-acting beta agonist, your asthma may be getting worse. Call your doctor.

If your sputum (the matter you cough up during an asthma attack) thickens or changes color from clear white to yellow, green, or gray, call your doctor; these changes may be signs of an infection.

To relieve dry mouth or throat irritation caused by formoterol inhalation, rinse your mouth with water, chew gum, or suck sugarless hard candy after using formoterol.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
