Doses of CAYSTON should be taken at least 4 hours apart (for example: morning, after school or work, and before bed). The dosing times are flexible enough to allow you to take CAYSTON according to your schedule as long as you take it 3 times a day with at least 4 hours in between each dose.

To ensure that you get your complete dose of CAYSTON, make sure you are in an environment with a flat, stable surface to prepare your doses and sitting in an upright position to take your dose. You’re free to create a flexible dosing schedule that’s right for you.

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:
