Pa infects the lungs of nearly everyone with CF at some time during their life

What are the effects of Pseudomonas aeruginosa?

Pa can cause lung function to worsen in patients with CF, and is a leading cause of chronic lung infection in patients with CF

Over time, with Pa in your lungs, you may

  • Develop a cough that doesn't go away
  • Have more mucus in your lungs
  • Feel tightness in your chest
  • Have a hard time catching your breath

If Pa infection is not properly managed, it can continue to damage the lungs and make breathing even more difficult

Inhaled antibiotics are commonly prescribed by doctors to treat chronic lung infection in patients with CF and Pa. It is important that inhaled antibiotics be taken as prescribed.
