Patient Education

Lumacaftor and Ivacaftor


Lumacaftor and ivacaftor is used to treat certain types of cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction) in adults and children 2 years of age and older. Lumacaftor is in a class of medications called cystic fibrosis transmembrane conductance regulator (CFTR) correctors. Ivacaftor is in a class of medications called cystic fibrosis transmembrane conductance regulator (CFTR) potentiators. Both of these medications work by improving the function of a protein in the body to decrease the build-up of thick mucus in the lungs and improving other symptoms of cystic fibrosis.
