Kalydeco® should always be taken with a fat-containing food to ensure you get the proper amount in your system.   Each dose should be taken just before or just after fat-containing food. Meals and snacks recommended in the Canadian Food guide contain adequate amounts of fat.
If you miss a dose of Kalydeco® and it is within 6 hours of when you usually take it, take your dose as prescribed with fat-containing food as soon as possible. If you miss a dose and it is more than 6 hours after the time you usually take it, skip that dose only and take the next dose when you usually take it. Do not take 2 doses at the same time to make up for your missed dose.

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. Ivacaftor is a "cystic fibrosis transmembrane conductance regulator (CFTC) potentiator". 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. Ivacaftor helps this CFTR protein channel or "open the gates" more often allowing more salt to pass through.  The thick mucus is reduced and cystic fibrosis symptoms lessen.
