PERFOROMIST® (formoterol fumarate) Inhalation Solution is used for the long-term treatment of chronic obstructive pulmonary disease (COPD) including chronic inflammation of the lungs (bronchitis) and emphysema. It is only to be used with a jet nebulizer and is taken twice daily (morning and evening).

Important Limitations for Use:

  • PERFOROMIST should not be used as a rescue medication
  • PERFOROMIST is not indicated to treat asthma. The safety and effectiveness of PERFOROMIST Inhalation Solution in asthma has not been established.


PERFOROMIST Inhalation Solution belongs to a class of drugs called long-acting beta2-agonists (LABA). People with asthma who take LABA such as PERFOROMIST Inhalation Solution have an increased risk of death from asthma problems. Do not use PERFOROMIST Inhalation Solution if you have asthma without using a long-term asthma control medicine.


Warnings and Precautions
PERFOROMIST Inhalation Solution should not be used instead of rescue inhaler or nebulized medicine for the treatment of acute symptoms. Extra doses of PERFOROMIST Inhalation Solution should not be used for that purpose since overuse can cause serious heart problems, including death. Acute or sudden symptoms should be treated with an inhaled short-acting beta2-agonist.

Seek immediate medical attention if:

  • your symptoms quickly worsen despite recommended doses of PERFOROMIST Inhalation Solution
  • PERFOROMIST Inhalation Solution treatment becomes less effective
  • you need more inhalations of a short-acting beta2-agonist (rescue inhaler or nebulized medicine) than usual.

Do not use PERFOROMIST Inhalation Solution with other LABA medicines for any reason.
