A small number of people with cystic fibrosis have a certain changed (mutated) gene called the G551D mutation. If you have this changed gene, the medicine ivacaftor (Kalydeco) can target the genetic cause of your lung problems and may help improve lung function. Talk to your doctor if you want more information about it.
What to think about
Some medicines work better for
some people than for others. A medicine that works well for one person may not
work for someone else. It can take time to find the medicines that work best
for you or your child.
