Maviret 50 mg / 20 mg coated granules in sachet – patient leaflet, side effects, dosage

1. What Glecaprevir/Pibrentasvir is and what it is used for

Glecaprevir/Pibrentasvir is an antiviral medicine used to treat children aged 3 years and older with recently acquired ('acute') or long-term ('chronic') hepatitis C. This is an infectious disease that affects the liver, caused by the hepatitis C virus. Glecaprevir/Pibrentasvir contains the active substances glecaprevir and pibrentasvir.

Glecaprevir/Pibrentasvir works by stopping the hepatitis C virus from multiplying and infecting new cells. This allows the infection to be eliminated from the body.

2. What you need to know before your child takes Glecaprevir/Pibrentasvir

Do not give Glecaprevir/Pibrentasvir if:

• your child is allergic to glecaprevir, pibrentasvir or any of the other ingredients of this medicine (listed in section 6).
• your child has severe liver problems other than from hepatitis C.

• your child is taking the following medicines:

  • atazanavir (for HIV infection)
  • atorvastatin or simvastatin (to lower blood cholesterol)
  • carbamazepine, phenobarbital, phenytoin, primidone (normally used for epilepsy) • dabigatran etexilate (to prevent blood clots)
  • ethinyl oestradiol-containing medicines (such as contraception medicines, including vaginal rings, transdermal patches and tablets)
  • rifampicin (for infections)
  • St. John’s wort (Hypericum perforatum) (herbal remedy used for mild depression).

Do not give Glecaprevir/Pibrentasvir to your child if any of the above apply. If you are not sure, talk to your child’s doctor or pharmacist before giving Glecaprevir/Pibrentasvir.

Warnings and precautions

Talk to your child’s doctor if they have the following because the doctor may want to check your child more closely:

• liver problems other than hepatitis C
• current or previous infection with the hepatitis B virus
• diabetes. Your child may need closer monitoring of their blood glucose levels and/or adjustment of diabetes treatment after starting Glecaprevir/Pibrentasvir. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like Glecaprevir/Pibrentasvir.

Blood tests

Your child’s doctor will test their blood before, during and after treatment with Glecaprevir/ Pibrentasvir. This is so that the doctor can decide if:

• Your child should take Glecaprevir/Pibrentasvir and for how long

• The treatment has worked and your child is free of the hepatitis C virus.

Step 3. Gather materials

Place the following on a clean surface:

• Box with sachets in it
• Soft food
• Bowl to use for mixing
• Teaspoon
• Scissors

Step 4. Measure food

• Place a small amount (1-2 teaspoons or 5-10 mL) of soft food into a bowl.

• The granules inside the sachets are very small, so placing food in the bowl first will help contain them.

  Step 5. Prepare sachet

  • Look for the dotted line on the sachet to find the top end. • Hold the sachet upright and tap the top of the sachet. Keep tapping until all the granules inside fall to the bottom.
  • Feel top area of sachet thoroughly to make sure all granules are at the bottom.

Step 6. Cut top of sachet

• Pinch the sachet in the centre, above the granules inside. • Use scissors to cut the top of the sachet completely off.

Be Careful: Granules are very small and can fall out easily.

Step 7. Pour sachet

• Make sure the sachet is fully open.
• Carefully pour all granules (pink and yellow) out of the sachet into the bowl of food.
• Tap sachet to get all the granules out.
• Repeat for each sachet for your child’s daily dose.

Step 8. Check sachet

Look inside each sachet to make sure there are no granules left inside.

Do not leave any granules behind as the medicine will not work as well if the full dose is not taken.

Step 9. Mix

• Use the teaspoon to gently stir the granules into the food. • Do not crush the granules. If the granules are crushed, they will taste bitter.
• Do not store the mixture, give it to your child immediately.

If not given within 5 minutes, the mixture may taste bitter. If not given within 15 minutes, the medicine may be less effective. Throw away and start again.

Step 10. Give the medicine

• Scoop a small amount of mixture onto the teaspoon. • Make sure your child swallows the mixture without chewing. • Repeat until your child has taken all the mixture.
• If any granules are left, add more food and mix. Then finish the dose.
• Make sure your child takes the full dose of the medicine.

• ^! If your child misses a dose, see Section 3 “How to take Glecaprevir/ Pibrentasvir” for further information.
