Need help staying on track with CAYSTON?


Before you receive your first shipment of CAYSTON, it is important to complete and understand the following steps:

Step 1: Enroll into the Cayston Access Program® (CAP)

Your cystic fibrosis (CF) care team will ask you to complete a Cayston Access Program application form [English] [Español], which is required to provide you with the ALTERA® Nebulizer System, along with additional methods of access and support.

Step 2: Choose your Specialty Pharmacy

CAYSTON is only available through specialty pharmacies. Most insurance plans will automatically select a specialty pharmacy for you. If you are able to choose one yourself, make sure that specialty pharmacy is covered by your insurer. Learn more about specialty pharmacies. You can also call the Cayston Access Program at 1-877-7CAYSTON 8 AM – 8 PM EST, Monday through Friday with any questions.

Step 3: Schedule your first CAYSTON shipment

Call your specialty pharmacy to order and confirm a delivery date for your first shipment of CAYSTON. If you do not take this step, your CAYSTON will not be delivered to your home.

Remember: Your specialty pharmacy may call you from an unknown number to set up an account—be sure to check your voicemail for messages from missed calls.
