How to Store and Prepare a Dose of CAYSTON® | CAYSTON®

CAYSTON can be stored at room temperature for up to 28 days

Always keep your CAYSTON and saline together. CAYSTON and saline can be stored at room temperature (less than 77°F) for up to 28 days and should be refrigerated at 36°F to 46°F (2°C to 8°C) for longer periods. Do not use CAYSTON if it has been stored at room temperature for more than 28 days. It should also be protected from light.

Before taking a dose of CAYSTON

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 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)

preparing your cayston for inhalation

You will need the following supplies:

  • 1 amber-colored CAYSTON vial covered by a metal seal with a blue cap or a metal seal only
  • 1 ampule of saline (diluent)
  • The Altera Nebulizer System

get the materials

  1. Take 1 amber vial of CAYSTON and 1 ampule of saline from the carton. Separate the saline ampule by gently pulling apart. (Note: If the saline looks cloudy, throw it away and use another ampule.)

open the cayston

  1. 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 or blue cap on the top (Figure 1) and pulling down (Figure 2) to carefully remove the entire metal ring from the vial (Figure 3). Safely dispose of the ring in household garbage. Carefully remove the rubber stopper.

open the saline

  1. Open the ampule of saline by twisting off the tip. Squeeze out the contents completely into the vial (Figure 4). Next, close the vial with the rubber stopper and gently swirl the vial until the powder has completely dissolved and the liquid is clear.
