WHAT IS CAYSTON AND HOW DOES IT WORK?
- CAYSTON is an antibiotic, belonging to a group of medicines called monobactams.
- CAYSTON is used to help people who have Cystic Fibrosis (CF).
CF is a genetic disease that affects a number of organs in the body. The lungs are often clogged with thick, sticky mucus that may lead to chronic airway infections. CAYSTON is not a cure for this disease.
- CAYSTON is used to fight lung infections caused by bacteria such as Pseudomonas aeruginosa (P. aeruginosa).
- When you inhale CAYSTON with your Altera™ Nebulizer System, it will enter your lungs and contact the P. aeruginosa bacteria that are present. CAYSTON works by decreasing the number of P. aeruginosa bacteria living in your lungs to improve your respiratory symptoms and lung function.
