1. What is Bylvay and what is it used for

Bylvay contains the active substance odevixibat. Odevixibat is a medicine that increases the elimination of certain 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 intestine. Odevixibat blocks the mechanism that normally reabsorbs them from the intestine after they have done their job. This allows them to be eliminated from the body through the feces.

Bylvay is used to treat progressive familial intrahepatic cholestasis (PFIC) in patients aged 6 months or older. PFIC is a liver disease caused by the accumulation of bile acids (cholestasis) that worsens over time and is often accompanied by severe itching.

2. What you need to know before you take Bylvay

Warnings and precautions

Consult your doctor or pharmacist before starting treatment with Bylvay:

  • if you have been diagnosed with a complete absence or lack of function of the bile salt export pump protein;
  • if you have severe liver dysfunction;
  • if you have reduced stomach or intestinal motility or reduced bile acid circulation between the liver, bile, and small intestine due to medications, surgical interventions, or diseases other than PFIC, as this may reduce the effect of odevixibat.

Consult your doctor if you experience diarrhea while taking Bylvay. It is recommended that patients with diarrhea drink sufficient fluids to avoid dehydration.

During treatment with Bylvay, elevated levels of liver enzymes may be observed in liver function tests. Before starting treatment with Bylvay, your doctor will measure your liver function to check the functioning of your liver. Your doctor will perform regular checks to monitor your liver function.

Before and during treatment, your doctor may also check your blood levels of vitamins A, D, and E and your INR (international normalized ratio, which measures your risk of bleeding).

Children

Using Bylvay with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Treatment with odevixibat may affect the absorption of fat-soluble vitamins, such as vitamins A, D, and E, and some medicines.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, consult your doctor before using this medicine.

The use of Bylvay is not recommended during pregnancy or in women of childbearing age who are not using contraceptive methods.

Instructions

Instructions for opening the capsules and sprinkling the contents over some food:

Step 1. Place a small amount of soft food in a bowl (2 tablespoons/30 ml of yogurt, apple sauce, mashed banana or carrot, chocolate pudding, rice pudding, or oatmeal). The food should be at room temperature or cooler.

Two hands holding blue devices dispensing small circular particles over a white surface

Step 3:

  • Separate them to empty the contents into the bowl containing the soft food.
  • Gently tap the capsule to ensure all the granules come out.
  • Repeat the above step if more than one capsule is needed for the dose.

Step 4:

  • Mix the capsule contents gently with the soft food.
  • Take the complete dose immediately after mixing. Do not store the mixture for later use.
  • Drink a glass of water after the dose.
  • Discard the empty capsule shells.

Instructions for opening the capsules and sprinkling the contents into a suitable liquid for the age:

Do not administer the medication through a baby bottle or a medicine cup, as the granules will not pass through the opening. The granules will not dissolve in liquids.

Contact your pharmacy if you do not have an appropriate oral syringe to administer the medication at home.

Hands opening a blue capsule with granular contents falling into a glass with transparent liquid

Step 1:

  • Hold the capsule horizontally by both ends and twist in opposite directions.
  • Separate them to empty the contents into a small cup or glass. Gently tap the capsule to ensure all the granules come out. Repeat this step if more than one capsule is needed for the dose.
  • Add 1 teaspoon (5 ml) of a suitable liquid for the age (e.g., breast milk, formula, or water).
  • Allow the granules to settle in the liquid for approximately 5 minutes to allow them to become completely wet (the granules will not dissolve).

Step 2:

  • After 5 minutes, insert the tip of the oral syringe completely into the mixture cup.
  • Slowly pull the syringe plunger up to draw the liquid and granule mixture into the syringe. Gently push the plunger down again to return the mixture to the cup. Repeat this process 2 or 3 times to ensure complete mixing of the granules in the liquid.

Step 3:

  • Draw the entire contents into the oral syringe by pulling the plunger up to the end of the syringe.

Step 4:

  • Place the tip of the oral syringe in the front of the child's mouth between the tongue and the side of the mouth, and then gently push the plunger down to administer a stream of the liquid and granule mixture between the tongue and the side of the child's mouth. Do not administer a stream of the liquid and granule mixture into the back of the child's throat, as this could cause gagging or choking.
  • If there are any remaining mixture in the cup, repeat steps 3 and 4 until the complete dose has been administered.
  • Administer the complete dose immediately after mixing. Do not store the liquid and granule mixture for later use.
  • Give the child breast milk, formula, or another suitable liquid for the age to drink after the dose.
