Patient Education

Elexacaftor, Tezacaftor, and Ivacaftor


The combination of elexacaftor, tezacaftor, 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 12 years of age and older. It should be used only in people with a certain genetic make-up. Your doctor may order a blood test to help decide if this medication is right for you. Elexacaftor and tezacaftor are 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. 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 improve other cystic fibrosis symptoms.
