It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

What KALYDECO is used for

KALYDECO is for the chronic treatment of cystic fibrosis (CF) in patients aged 2 years and older who have a G551D or other gating (class III) mutation in the CFTR gene.

KALYDECO is for the chronic treatment of cystic fibrosis (CF) in patients aged 6 years and older who have an R117H mutation in the CFTR gene.

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, clogs the lungs and makes it easier for germs to grow. KALYDECO is a medicine that works by improving the flow of chloride and water in patients with cystic fibrosis who have a certain genetic defect.

How KALYDECO works

KALYDECO belongs to a group of medicines called “cystic fibrosis transmembrane conductance regulator (CFTR) modulators.”

In people with a G551D or other gating (class III) mutation and in people with an R117H mutation, the CFTR protein is present in normal amounts but its ability to allow chloride to pass through is reduced. KALYDECO is a CFTR potentiator, which is a drug that increases the opening of the CFTR protein, allowing more chloride to pass through.

KALYDECO is not addictive.

How to take KALYDECO

Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in this leaflet.

How much to take

Your doctor will tell you how much KALYDECO you need to take each day. This may depend on your condition and whether or not you are taking any other medicines.

KALYDECO dosing recommendations for patients aged 2 years and older are as follows:

  • Patients weighing less than 14 kg: one sachet of 50 mg granules taken orally every 12 hours (total daily dose of 100 mg)

  • Patients weighing 25 kg or more: one 150 mg tablet taken orally every 12 hours (total daily dose of 300 mg)

If you have liver problems, your doctor may need to reduce the dose as your liver is not clearing ivacaftor as fast as in people who do not have problems with liver function.

How to take it

KALYDECO is for oral use.

Tablets
Take 1 tablet (150 mg) of KALYDECO every 12 hours by mouth with a fat-containing meal or snack.

Granules
Each sachet is for single use only.

Giving KALYDECO to your child

  • Hold sachet of granules with cut line on top.
  • Shake sachet gently to settle contents.
  • Tear or cut sachet open along cut line.
  • Mix the entire content of a sachet with 5 mL of age-appropriate soft food or liquid. Food or liquid should be at room temperature or below. Some examples of age-appropriate soft foods or liquids include puréed fruits or vegetables, yogurt, applesauce, water, milk, or juice.
  • Once mixed, give the product to your child immediately. If this is not possible, give it within one hour after mixing. Ensure that the mixture is completely and immediately consumed.
  • A fat-containing meal or snack should be given to your child just before or just after dosing.

If you forget to take it

Take the missed dose if less than 6 hours have passed since the time you missed the dose. Otherwise, wait until your next scheduled dose as you normally would.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
