Patients with cystic fibrosis and chronic Pseudomonas aeruginosa (Pa) can experience respiratory symptoms such as coughing, wheezing, and mucus production. CAYSTON is an inhaled antibiotic that helps suppress Pa bacteria and could reduce your symptoms. Ask your doctor how CAYSTON can help you breathe better.

CAYSTON is a prescription inhaled antibiotic used to improve breathing symptoms in people with cystic fibrosis (CF) who have a lung infection due to Pseudomonas aeruginosa (Pa). CAYSTON is not a treatment for infections caused by other bacteria or viruses, such as the common cold. CAYSTON is used only with the Altera® Nebulizer System. It is not known if CAYSTON is safe and effective in children under the age of 7 or in patients with FEV1 <25% or >75% predicted.
