Duaklir Pressair is indicated to control and prevent symptoms such as wheezing and shortness of breath caused by ongoing lung disease, specifically chronic obstructive pulmonary disease (COPD), which encompasses chronic bronchitis and emphysema. 

Managing these symptoms is essential for enabling individuals to stay active despite their breathing difficulties.

This inhaler contains two medications: aclidinium and formoterol. Aclidinium belongs to the class of drugs known as anticholinergics, while formoterol belongs to the class of drugs known as long-acting beta-agonists (LABAs). Both are bronchodilators. Both drugs work by relaxing the muscles around the airways, facilitating their opening and thereby enabling easier breathing. 


  • Use it exactly as directed by your healthcare provider. This includes dosage (usually twice daily), frequency (morning and evening), and inhalation technique (inhalation by mouth, not eyes).
  • Use it regularly at the same times each day to maximize the benefit.
  • Maintain a consistent schedule and avoid increasing the dose or using it more often without consulting your healthcare provider.
  • Follow your healthcare provider's instructions regarding other inhalers, especially if you are using a quick-relief inhaler regularly. You might need to switch to using it only "as needed" for sudden breathing problems.
  • Learn which inhaler is for daily use and which is for quick relief.
  • Develop an action plan with your healthcare provider for worsening symptoms, increased quick-relief inhaler use, or loss of effectiveness of the quick-relief inhaler. This plan should include when to seek medical attention.
  • Inform your healthcare provider if your condition doesn't improve or worsens.


  • Don't increase your dose or use it more often without consulting your healthcare provider.
  • Don't stop using it without talking to your healthcare provider first.
  • Don't exhale into the device.
  • Don't get any medication in your eyes.
  • Don't use your quick-relief inhaler on a regular schedule unless your healthcare provider instructs you to do so.
