What is Arformoterol?

Arformoterol is a bronchodilator. It works by relaxing muscles in the airways to improve breathing.

Arformoterol inhalation is used to prevent bronchoconstriction in people with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. Arformoterol will not treat a bronchospasm attack that has already begun.

Arformoterol may also be used for purposes other than those listed in this medication guide.

What is the most important information I should know about Arformoterol?

Do not use this medication to treat a sudden bronchospasm attack. It will not work fast enough to reverse your symptoms. Use another, faster-acting inhalation medication to treat sudden attacks of bronchospasm.

Call your doctor right away if you feel that this medicine is not working as well as usual, or if you think you need to use more than usual. An increased need for medication could be an early sign that your condition is getting worse.
