In a Clinical Trial, Patients Taking Cayston for 28 Days Reported:

  • Improved respiratory symptoms (ie, cough, wheezing, sputum production)
  • An average 10% increase of their starting FEV1 (L) compared to placebo
  • Fast nebulization time of about 2-3 minutes, 3 times a day, at least 4 hours apart

Cayston is approved based on three Phase 3 clinical studies with a total of 344 patients. To learn more about the design of the study, During the study, 80 people received Cayston 75 mg, 3 times a day, and 84 people received placebo (a substance containing no medication and which has no specific activity for the condition being treated) 3 times a day for 28 days by inhalation using the Altera® Nebulizer System. All participants used an inhaled bronchodilator (a medicine used to relax and open the airways) prior to receiving Cayston. Patients were receiving standard care for CF, including drugs to help with airway clearance. At the end of 28 days of treatment, the results for people who took Cayston were compared to those who took placebo.click here.

Important Safety Information

What is Cayston?

Cayston is a prescription inhaled antibiotic used to improve breathing symptoms in people with cystic fibrosis (CF) who have a lung infection due to Pseudomonas aeruginosa (Pa). Cayston is a treatment for infections caused by Pa, and not for infections caused by other bacteria or viruses, such as the common cold. It is not known if Cayston is safe and effective in children under the age of 7 or in patients with FEV1 <25% or >75% predicted.

Who should not take Cayston?

Do not take Cayston if you are allergic to aztreonam (AZACTAM®).

    If you have a history of allergy to antibiotics such as penicillins, cephalosporins, and/or carbapenems, you may also be allergic to Cayston. It is important to tell your healthcare provider about any medication allergies you may have.
  • Trouble breathing right after treatment with Cayston (bronchospasm). To decrease the chance of this happening, be sure to use your inhaled bronchodilator medicine before each treatment with Cayston. Stop treatment if chest tightness develops during nebulizer use.
