Always take Cayston exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
- Take Cayston 3 times a day for the 28-day treatment course. Each of the three doses should be taken by inhalation at least four hours apart, using an Altera Nebuliser Handset. You can use either an Altera Control Unit or an eFlow rapid Control Unit with the Altera Handset.
- Each dose consists of one vial of Cayston mixed with one ampoule of solvent. Cayston needs to be mixed with a solvent before being inhaled through the Altera Nebuliser.
Put the prepared Cayston solution in the Altera Nebuliser Handset (see below). Each treatment takes about 2 to 3 minutes to inhale.
Use a bronchodilator before each dose of Cayston. Short acting bronchodilators can be taken between 15 minutes and 4 hours and long acting bronchodilators can be taken between 30 minutes and 12 hours prior to each dose of Cayston.
If you are using other therapies to treat cystic fibrosis, the recommended order is as follows:
1. bronchodilator
2. dornase alfa (a medicine that helps to dissolve the thick mucous produced in the lungs)
3. chest physiotherapy
4. any other inhaled medicines and finally:
5. Cayston.
Do not mix Cayston with any other medicines in the Altera Nebuliser Handset.
- Do not put other medicines in the Altera Nebuliser Handset.
- Do not put the intravenous (injectable) form of aztreonam in the Altera Nebuliser Handset. Intravenous aztreonam is not suitable for inhalation.
How to take Cayston using the Altera Nebuliser Handset
You will need the following:
One amber-coloured vial of Cayston
One plastic ampoule of solvent (0.17% w/v sodium chloride)
An Altera Nebuliser Handset containing an Altera Aerosol Head connected to an Altera Control Unit (678G) or an eFlow rapid Control Unit (178G)
You must use the Cayston specific Altera Nebuliser Handset containing an Altera Aerosol Head. Do not try to take Cayston using any other type of nebuliser handset (including the eFlow rapid handset).
Check that your nebuliser works properly before starting your treatment with Cayston. Read the manufacturer?s instructions for use provided with your Altera Nebuliser System carefully.
Preparing your Cayston for inhalation
- Do not prepare Cayston until you are ready to administer a dose.
- Do not use Cayston if you notice that the package has been tampered with.
- Do not use Cayston if it has been stored outside a refrigerator for more than 28 days.
- Do not use the solvent or prepared Cayston if it is cloudy or if there are particles in the solution.
1. Take one amber vial of Cayston and one ampoule of solvent from the box. Solvent ampoules must be separated by gently pulling them apart.
2. Gently tap the amber vial containing the Cayston so that the powder settles at the bottom. This helps to ensure that you get the proper dose of medicine.
3. Open the amber vial by lifting up the metal flap on the top (Figure 1a) and pulling down (Figure 1b) to carefully remove the entire metal ring and overcap from the vial (Figure 1c). Safely dispose of the ring. Carefully remove the rubber stopper.
4. Open the ampoule of solvent by twisting off the tip. Squeeze out the contents completely into the vial (Figure 1d). Next, gently swirl the vial until the powder has completely dissolved and the liquid is clear.
It?s best to use Cayston immediately after you have made up the solution. But, if you cannot use the prepared dose straight away, replace the stopper in the vial and store in a refrigerator. Use the prepared solution within 8 hours.
Preparing the Altera Nebuliser to take your Cayston
1. Make sure the AlteraNebuliser Handset is on a flat, stable surface.
2. Remove the medicine cap by twisting anticlockwise.
3. Pour all of the prepared Cayston from the vial into the Altera Nebuliser Handset medicine reservoir (Figure 2a). Be sure to completely empty the vial. Gently tap the vial against the side of the medicine reservoir if necessary.
4. Close the medicine reservoir by aligning the tabs of the medicine cap with the slots on the reservoir. Press down and turn the cap clockwise as far as it will go (Figure 2b).

Using the Altera Nebuliser to take your Cayston
1. Begin your treatment. Sit in a relaxed, upright position. Hold the handset level and place the mouthpiece in your mouth and close your lips around it (Figure 3).
Figure 3
Keep the handset level.
2. Press and hold the On/Off button on the Control Unit for a few seconds. You will hear one ?beep? and the status light will turn green.
3. After a few seconds, an aerosol mist will begin to flow into the Aerosol Chamber of the Altera Nebuliser Handset. If aerosol mist does not begin to flow, please refer to the Altera manual for information.
4. Breathe normally (inhale and exhale) through the mouthpiece. Avoid breathing through your nose. Continue to inhale and exhale comfortably until the treatment is finished.
5. When all of the medicine has been delivered, you will hear a tone that means ?treatment complete? (2 beeps).
6. When treatment is complete, open the medicine cap to ensure that all medicine has been used. A few drops of medicine may remain in the reservoir at the end of treatment. If there is more than a few drops of liquid left, replace the medicine cap and restart treatment.
7. Once treatment is complete, disconnect the Control Unit and take apart the Altera Nebuliser Handset for cleaning and disinfecting. For complete details on cleaning and disinfecting refer to the manufacturer?s instructions for use provided with your Altera Nebuliser Handset.
What if I need to stop my treatment before I?ve finished?
8. If for any reason you must stop the treatment before you have finished, press and hold the On/Off button for one full second. To re-start the treatment, press and hold the On/Off button for one full second and then restart the treatment.
Replacing the Altera Nebuliser Handset
The Altera Nebuliser Handset is designed to last for three 28-day courses of Cayston when used as directed. After this time replace your Altera Nebuliser Handset, including the aerosol head. If you notice that the performance has changed before this time (for instance, if it takes longer to produce a mist, more than 5 minutes), please refer to the Altera Nebuliser instructions for use.
