ℹ️ 1. What Bylvay is and what it is used for

Bylvay contains the active substance odevixibat. Odevixibat is a medicine which increases the removal of substances called bile acids from the body. Bile acids are components of the digestive fluid called bile, which is produced by the liver and secreted into the intestines. Odevixibat blocks the mechanism that normally reabsorbs them from the intestines after they have done their job. This allows them to pass out of the body in the stool .

Bylvay is used to treat progressive familial intrahepatic cholestasis (PFIC) in patients aged 6 months or older. PFIC is a liver disease caused by build -up of bile acids (cholestasis ) that gets worse over time and is often accompanied with severe itch ing.

45 Instructions Instructions to open capsules and sprinkle the contents on food:

Step 1. Place a small amount of soft food into a bowl (2 tablespoons/30 mL of yoghurt, apple sauce, banana or carrot puree, chocolate pudding, rice pudding or oatmeal porridge). Food should be at or below room temperature.

Step 2:

  • Hold the capsule horizontally at both ends, twist in opposite directions.

Step 3:

  • Pull apart to empty the contents into the bowl of soft food.
  • Gently tap the capsule to ensure that all pellets come out
  • Repeat the previous step if the dose requires more than one capsule.

Step 4:

  • Gently mix the contents of the capsule into the soft food.
  • Take the entire dose immediately after mixing. Do not store the mixture for future use.
  • Drink a glass of water following the dose .
  • Dispose of the empty capsule shells .

46 Instructions to open capsules and sprinkle the contents in an age-appropriate liquid :

Do not administer via a bottle or “sippy cup” because the pellets will not pass through the opening.

Pellets will not dissolve in liquids.

Contact your pharmacy if you do not have a suitable oral syringe for administration at home.

Step 1:

  • Hold the capsule horizontally at both ends, twist in opposite directions.
  • Pull apart and empty the contents into a small cup or glass.
  • Gently tap the capsule to ensure that all pellets come out .

Repeat this if the dose requires more than one capsule .

  • Add 1 teaspoon (5 ml) of an age-appropriate liquid (e.g. breast milk, infant formula or water).
  • Let the pellets sit in the liquid for approximately 5 minutes to allow complete wetting (pellets will not dissolve).

Step 2:

  • After 5 minutes, place the tip of the oral syringe completely into the mixing cup.
  • Pull the plunger of the syringe up slowly to withdraw the liquid/pellet mixture into the syringe. Gently push the plunger down again to expel the liquid/pellet mixture back into the mixing cup. Do this 2 to 3 times to ensure complete mixing of the pellets into the liquid.

Step 3:

  • Withdraw the entire contents into the oral syringe by pulling the plunger on the end of the syringe.

Step 4:

  • Place the tip of the oral syringe into the front of the child’s mouth between the tongue and the side of the mouth, and then gently push the plunger down to squirt the liquid/pellet mixture between your child’s tongue and the side of the mouth. Do not squirt liquid/pellet mixture in the back of the child’s throat because this could cause gagging or choking.
  • If any pellet/liquid mixture remains in the mixing cup, repeat Step 3 and Step 4 until the entire dose has been administered.
  • Give the entire dose immediately after mixing. Do not store the liquid/pellet mixture for future use.

47 • Give breast milk, infant formula or other age -appropriate liquid to drink following the dose.

  • Dispose of the empty capsule shells.
