What is CAYSTON?

CAYSTON is a prescription inhaled antibiotic. CAYSTON is used to improve breathing symptoms in people with cystic fibrosis (CF) who have Pseudomonas aeruginosa (P. aeruginosa) in their lungs.

CAYSTON is only for infections caused by bacteria. It is not for infections caused by viruses, such as the common cold.

CAYSTON is used only with the Altera® Nebulizer System.

It is not known if CAYSTON is safe and effective in children under the age of 7.

Who should not take CAYSTON?

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

What should I tell my doctor before taking CAYSTON?

Before taking CAYSTON, tell your doctor if you:

  • are allergic to any antibiotics.
  • are pregnant or plan to become pregnant.
  • are breast-feeding or plan to breast feed. Talk to your doctor about the best way to breast feed your baby if you take CAYSTON.

Tell your doctor about all the medicine you take, including prescription and non-prescription medicines, vitamins and herbal supplements.

Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

How should I take CAYSTON?

  • Take CAYSTON exactly as prescribed by your doctor.

  • Doses of CAYSTON should be taken at least 4 hours apart (for example: morning, after school, and before bed).
  • CAYSTON should be taken for 28 days.
  • CAYSTON is taken as a breathing treatment (inhalation) with the Altera Nebulizer System. Do not use any other nebulizer for your CAYSTON treatment.
  • You should use an inhaled bronchodilator (a type of medicine used to relax and open your airways) before taking a dose of CAYSTON. If you do not have an inhaled bronchodilator, ask your doctor to prescribe one for you.
  • If you are taking several medicines or treatments to treat your cystic fibrosis, you should take your medicines or other treatments in this order:
    1) bronchodilator
    2) mucolytics (medicines to help clear mucus from your lungs)
    3) CAYSTON
  • You should take CAYSTON as prescribed, in courses of 28 days on CAYSTON, followed by at least 28 days off CAYSTON, as directed by your doctor.
  • Do not mix CAYSTON with any other medicines in your Altera Nebulizer System.
  • Do not mix CAYSTON with the saline until right before you are ready to use it. Do not mix more than one dose of CAYSTON at a time.
  • Each treatment should take about 2 to 3 minutes.
  • If you miss a dose of CAYSTON, you can still take all 3 daily doses as long as they are at least 4 hours apart.
  • It is important for you to finish taking the full 28-day course of CAYSTON even if you are feeling better. If you skip doses or do not finish the full 28-day course of CAYSTON, your infection may not be fully treated and CAYSTON may not work as well as a treatment for infections in the future.
  • See the end of this Patient Information leaflet for the Patient Instructions for Use on how to take CAYSTON the right way.

Needed supplies - Illustration

Check to make sure that your Altera Nebulizer System works properly before starting your treatment with CAYSTON. See the manufacturer's instructions for use that comes with your Altera Nebulizer System. This should have complete information about how to put together (assemble), prepare, use, and care for your Altera Nebulizer System.

Step 1 Preparing your CAYSTON for inhalation

1. Mix (reconstitute) CAYSTON with the saline only when ready to take a dose. Take one amber vial of CAYSTON and one ampule of saline from the carton. Separate the saline ampules by gently pulling apart.

2. Look at the ampule of saline. If it looks cloudy do not use it. Throw away this ampule and get another ampule of saline.

3. Gently tap the vial so that the powder settles to the bottom of the vial. This helps you get the proper dose of medicine. Open the amber drug vial by lifting up the metal flap on the top (Figure 2) and pulling down (Figure 3) to carefully remove the entire metal ring from the vial (Figure 4). Safely dispose of the ring in household garbage. Carefully remove the rubber stopper.

5. After mixing CAYSTON with the saline, check to make sure the diluted medicine is clear. If it is cloudy or has particles in it, do not use this medicine. Throw away this dose of medicine and start over again with a new vial of CAYSTON and a new ampule of saline.

6. Use CAYSTON right away after you mix with the saline.

Step 2 Taking your CAYSTON treatment

See the manufacturer's instructions for use that comes with your Altera Nebulizer System for complete instructions on taking a treatment, and how to clean and disinfect your Altera Nebulizer Handset.

7. Make sure the handset is on a flat, stable surface.

8. Remove the rubber stopper from the vial, then pour all of the mixed CAYSTON and saline into the Medication Reservoir of the handset (Figure 6). Be sure to completely empty the vial, gently tapping the vial against the side of the Medication Reservoir if necessary. Close the Medication Reservoir (Figure 7).
