Clinical Effects

Cayston has been studied in a clinical trial that included people with cystic fibrosis who had the bacteria P. aeruginosa in their lungs. People in the study were randomly assigned to receive either Cayston or a placebo (a fake medicine with no active ingredients).
In this study, Cayston was shown to improve lung function more so than the placebo. In addition, people given Cayston reported a greater improvement in their respiratory symptoms after 28 days of treatment than people given the placebo. This included improvements in coughing, wheezing, and mucus production. Children treated with Cayston had a greater improvement in respiratory symptoms than adults treated with the medication.  

When and How to Use It

  • Try to take your Cayston doses at about the same times each day, at least four hours apart.
  • It will take two to three minutes to completely inhale each dose.
  • If you are using other inhaled medicines, use them first and take your dose of Cayston last.
  • Your healthcare provider may prescribe a bronchodilator medicine to take prior to each dose. He or she will instruct you about how and when to use the bronchodilator.
  • Do not use this medicine if it is cloudy or contains particles.
