1. Why am I using Hemlibra?

Hemlibra contains the active ingredient emicizumab. Hemlibra belongs to a group of medicines called monoclonal antibodies. Monoclonal antibodies are a type of protein that recognises and binds to a target in the body.

Hemlibra is used for routine prophylaxis in children, adolescents and adults with haemophilia A. This means it prevents bleeding or reduces the number of bleeding episodes. Hemlibra can be used for routine prophylaxis whether or not you have inhibitors to factor VIII.

Hemlibra works like factor VIII, by binding to the same clotting factors, which helps your blood to clot. However, because emicizumab is different to factor VIII, it works whether or not inhibitors are present.

This medicine is used to prevent bleeding or reduce the number of bleeding episodes in people with haemophilia A (“routine prophylaxis”). It is not to be used “on-demand” to treat bleeds once they occur.

2. What should I know before I use Hemlibra?


Do not use Hemlibra if:

  • you are allergic to emicizumab, any of the ingredients listed at the end of this leaflet, or any other proteins that are of hamster origin.
  • Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • have any other medical conditions
  • take any medicines for any other condition

If you are on routine prophylaxis with another agent before changing to Hemlibra:

  • you must stop prophylaxis with bypassing agents the day before starting Hemlibra.
  • you may continue prophylaxis with factor VIII for the first 7 days of treatment with Hemlibra.

If you have haemophilia A with inhibitors, it is very important you talk to your doctor about when and how to use bypassing agents to treat bleeds while using Hemlibra. Examples of bypassing agents include FEIBA-NF® and NovoSeven® RT.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant. Your doctor can discuss with you the risks and benefits involved.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Hemlibra and affect how it works:

FEIBA-NF, factor VIII inhibitor bypassing fraction (also known as activated prothrombin complex concentrate, aPCC):

  • Be aware there are serious and potentially life-threatening side effects of using FEIBA-NF while receiving Hemlibra (see Section 6. Are there any side effects).
  • Avoid using FEIBA-NF unless no other treatment options are available. However, if FEIBA-NF is required, talk to your doctor about how much to use. Do not use more than 50 units/kg of FEIBA-NF except under medical supervision.

Any other blood product, including NovoSeven® recombinant coagulation factor VIIa (also known as activated factor VII or eptacog alfa) or any form of factor VIII:

  • Talk to your doctor and carefully follow their instructions on using these medicines while receiving Hemlibra. You may need different amounts of these medicines or you may need to take different medicines.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Hemlibra.

4. How do I use Hemlibra?

Treatment with Hemlibra should be started under the supervision of a specialist doctor experienced in the treatment of haemophilia A.

Each time you use Hemlibra, record the name and batch number of the medicine.

How much to use

  • The dose of Hemlibra is dependent on your weight and frequency of injection.
  • Weeks 1 to 4: the dose is 3 milligrams for every 1 kilogram you weigh, injected once a week.
  • Week 5 and onwards: the dose will depend on whether you will continue to inject Hemlibra once a week or change to once every 2 weeks or once every 4 weeks.
  • Continue using your medicine for as long as your doctor tells you.

How to inject Hemlibra

Follow all instructions given to you by your haemophilia doctor or nurse carefully. They may differ from the information contained in this leaflet.

Read the Instructions for Use leaflet for detailed instructions on how to inject Hemlibra available at:

The Instructions for Use leaflet is also provided in each box of Hemlibra. If you do not understand the Instructions for Use, ask your haemophilia doctor or nurse for help.

  • Hemlibra is given by injection under the skin (subcutaneously).
  • Do not inject Hemlibra into a vein or muscle. To correctly insert the needle under the skin, pinch a fold of loose skin at the clean injection site with your free hand. Pinching the skin is important to ensure that you inject under the skin (into fatty tissue) but not any deeper (into muscle). Injecting into a muscle could result in an uncomfortable injection.
  • Your doctor or nurse will show you how to inject Hemlibra.
  • Once you have been trained, you should be able to inject this medicine at home, by yourself or with the help of a caregiver.
  • An injection should not be attempted until proper training has been given by the doctor or nurse on the correct injection technique.
  • If a child would like to self-inject the medicine, the child’s healthcare provider and the parent or caregiver should agree on whether it is appropriate for them to do so. Self-injection for children below the age of 7 years is not recommended.
  • Check the solution for particles or discolouration before using the medicine. It should be colourless to slightly yellow. Do not inject it if the solution is cloudy, discoloured, or contains visible particles.
  • Prepare and give the injection under clean and germ-free conditions using “aseptic technique”.
  • A syringe, a transfer needle with filter and an injection needle are needed to withdraw Hemlibra solution from the vial into the syringe and inject it under the skin. Syringes, transfer needles and injection needles are supplied separately to the medicine.
  • Make sure that you use a new injection needle for each injection and dispose of it after a single use.
  • Use a 1 mL syringe to inject up to 1 mL of Hemlibra solution. Use a 2-3 mL syringe to inject greater than 1 mL and up to 2 mL of Hemlibra solution.

If you forget to use Hemlibra

If you forget your scheduled injection, inject the forgotten dose as soon as possible before the day of the next scheduled dose. Then, continue to inject the next dose on your usual scheduled dosing day.

Do not inject a double dose on the same day to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your haemophilia doctor or nurse.

If you have trouble remembering to use your medicine, ask your haemophilia doctor or nurse for some hints.

If you use too much Hemlibra

If you think that you have used too much Hemlibra, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning. This is because you may be at risk of developing side effects such as blood clots. You may need urgent medical attention.

5. What should I know while using Hemlibra?

Things you should do

  • Carefully follow your doctor’s instructions about the use of bypassing agents when using Hemlibra if you have haemophilia A with inhibitors.
  • Tell your doctor that you are using Hemlibra if you are about to have any coagulation blood tests.

Call your doctor straight away if:

  • you or your caregiver feel Hemlibra is no longer helping your condition (e.g. if you notice an increase in bleeds). Your doctor will try to understand what is causing this. It is uncommon, but it might mean that you have developed antibodies to Hemlibra, which caused Hemlibra to stop working. If Hemlibra is no longer helping, a change to your haemophilia treatment may be required.
  • you or your caregiver notices any symptoms of thrombotic microangiopathy (TMA) or blood clots (see Section 6. Are there any side effects) and stop using Hemlibra and FEIBA-NF.
  • you become pregnant while using Hemlibra.

Keep all of your doctor’s appointments so that your progress can be checked.

Always carry with you your Patient Alert Card.

Remind any doctor, dentist, pharmacist or nurse you visit that you are using Hemlibra.

Things you should not do

  • Do not use Hemlibra “on-demand” to treat bleeds once they occur.
  • Do not use Hemlibra to treat any other complaints unless your doctor tells you to.
  • Do not give your medicine to anyone else, even if they have the same condition as you.
  • Do not stop using your medicine or change the dosage without checking with your doctor.
