Consumer Medicine Information (CMI)
This leaflet provides important information about using SYMDEKO. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using SYMDEKO.
Where to find information in this leaflet:

Why am I using SYMDEKO?

SYMDEKO contains the active ingredients Tezacaftor, Ivacaftor.
SYMDEKO is used for the treatment of cystic fibrosis (CF) in patients aged 6 years and older who are homozygous for the F508del mutation or who have at least one mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is listed in the approved indication.
SYMDEKO belongs to a group of medicines called “cystic fibrosis transmembrane conductance regulator (CFTR) modulators”. SYMDEKO includes two types of tablets, one contains tezacaftor and ivacaftor (morning dose) and the other contains ivacaftor (evening dose).
Tezacaftor is a “CFTR corrector” and works to increase the amount of protein at the cell surface.
Ivacaftor is a “CFTR potentiator” that makes the protein work better once it reaches the cell surface.
SYMDEKO is not addictive.
What is cystic fibrosis?
Cystic fibrosis is caused by genetic defects that limit the flow of chloride and water through cell membranes. As a result, the mucus in the lungs (and other organs) becomes thick and sticky, clogging the lungs and making it easier for germs to grow. SYMDEKO is a medicine that works by improving the flow of chloride and water in patients with cystic fibrosis who have a certain genetic defect.
