- are heterozygous for the F508del mutation and have one of the following mutations in the CFTR gene: P67L, D110H, R117C, L206W, R352Q, A455E, D579G, 711+3A→G, S945L, S977F, R1070W, D1152H, 2789+5G→A, 3272-26A→G, and 3849+10kbC→T.
Symdeko™should always be taken with fat-containing food eg foods that have been prepared with butter or oils, eggs, nuts, whole-milk dairy products (such as whole-milk, cheese, and yogurt) or meats. Swallow whole.

The recommended dose for adults, adolescents, and children aged 12 years and older is: one yellow tablet (tezacaftor 100 mg/ivacaftor 150 mg) in the morning and one blue tablet (ivacaftor 150 mg) in the evening, approximately 12 hours apart with fat-containing food.
Various mutations of the cystic fibrosis gene block the "gates" that allow the flow of salt across the cell membranes. This causes mucus to become thick and clog the lungs. The CFTR protein is a channel at the surface of the cells that allows the movement of particles such as chloride in and out of the cell, contributing to salt and water balance. Symdeko™ contains two medications: tezacaftor and ivacaftor. Tezacaftor is a CFTR "Corrector" which increases the amount of the CFTR protein at the surface of the cell, and ivacaftor is a CFTR "Potentiator" which helps this CFTR protein channel or "open the gates" more often allowing more salt to pass through. The thick mucus is then reduced and cystic fibrosis symptoms lessen.
