1. What Maviret is and what it is used for

Maviret is an antiviral medicine used to treat children aged 3 years and older with long-term (‘chronic’) hepatitis C. This is an infectious disease that affects the liver, caused by the hepatitis C virus. Maviret contains the active substances glecaprevir and pibrentasvir.

Maviret 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 Maviret

Do not give Maviret if:

  • your child is allergic to glecaprevir, pibrentasvir or any of the other ingredients of this medicine (listed in section 6 of this leaflet).
  • 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 and tablets)
    • rifampicin (for infections)
    • St. John’s wort (Hypericum perforatum), (herbal remedy used for mild depression).

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

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 medicine after starting Maviret. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like Maviret.

Blood tests

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

  • Your child should take Maviret and for how long
  • The treatment has worked and your child is free of the hepatitis C virus.

Children under 3 years old

Do not give this medicine to children under 3 years of age or weighing less than 12 kg. The use of Maviret in children under 3 years of age or weighing less than 12 kg has not yet been studied.

7. Instructions for use

Please read all of section 7 before using Maviret granules in sachets.

Step 1. Get the number of sachets as advised by your child’s doctor

If the weight of the child is from 12 kg to less than 20kg use 3 sachets once daily with approximately 1-2 teaspoons (about 5-10ml) of recommended food listed in step 2.

If the weight of the child is from 20 kg to less than 30kg use 4 sachets once daily with approximately 1-2 teaspoons (about 5-10ml) of recommended food listed in step 2.

If the weight of the child is from 30 kg to less than 45kg use 5 sachets once daily with approximately 1-2 teaspoons (about 5-10ml) of recommended food listed in step 2.

For children weighing 45 kg or more, talk to your child’s doctor about giving Maviret tablets.

Do not give more than 5 sachets.

Step 2. Choose suitable food to mix with Maviret granules

Suitable food should stick to the spoon. It must be soft, low in water content and can be swallowed without chewing.

Example of recommended foods:

  • Greek yogurt
  • Cream/soft cheese
  • Peanut butter
  • Chocolate hazelnut spread
  • Thick jam
  • Other food that sticks to the spoon

Note: in addition to the food used to mix the granules, Maviret should also be taken at the same time or straight after a meal or snack. The food used to mix the granules does not replace the meal or snack to take with Maviret.

Do not use food if it drips off a spoon as the medicine may dissolve quickly, taste bitter, and become less effective. Do not use food that your child is allergic to.

Example of foods not to use:

  • Liquids or watery food
  • Apple sauce
  • Food or liquid that is heated or frozen
  • Bread or other food that requires chewing
  • Non-Greek yogurt
  • Baby food
  • Food that drips off the spoon

For more information about suitable foods, contact your child’s doctor or pharmacist.

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 Maviret” for further information.

Step 11. Confirm dose for tomorrow

Check to make sure there are enough sachets for your child’s next dose of Maviret.

For replacement sachets or to refill your prescription contact your child’s doctor or pharmacist.
