Patient leaflet - Refixia 500 IU powder and solvent for solution for injection
What Refixia® is and what it is used for
What Refixia® is
Refixia® contains the active substance nonacog beta pegol. It is a long-acting version of factor
IX. Factor IX is a protein
naturally found in the blood that helps to stop bleeding.
What Refixia® is used for
Refixia® is used to treat and prevent bleeding in all groups of patients with haemophilia B (inborn factor
IX deficiency).
In patients with haemophilia B, factor
IX is missing or does not
work properly. Refixia® replaces this faulty or missing factor
IX and
helps blood to form clots at the site of bleeding.
2.
What you need to know before you use
Refixia®
Do not use Refixia®
•
if you are allergic to the active substance or any of the other
ingredients of this medicine (listed in section 6).
•
if you are allergic to hamster proteins.
If you are not sure if either of the above applies to you, talk to your doctor before using this medicine.
Warnings and precautions
Traceability
It is important to keep a record of the batch number of your Refixia. So, every time you get a new package of Refixia, note down the date and the batch number (which is on the packaging after Lot) and keep this information in a safe place.
Allergic reactions and development of inhibitors
There is a rare risk that you may experience a sudden and severe allergic reaction (e.g. anaphylactic reaction) to Refixia®. Stop the injection and contact your doctor or an emergency unit immedi-ately if you have signs of an allergic reaction such as rash, hives, weals, itching of large areas of skin, redness and/or swelling of lips, tongue, face or hands, difficulty in swallowing or breathing, shortness of breath, wheezing, tightness of the chest, pale and cold skin, fast heartbeat, and/or dizziness.
Your doctor may need to treat you promptly for these reactions. Your doctor may also carry out a blood test to check if you have developed factor
IX inhibitors (neutralising antibodies) against
your medicine, as inhibitors may develop together with allergic reactions. If you have such inhibitors, you may have a higher risk of sudden and severe allergic reactions (e.g. anaphylactic reaction) during future treatment with factor
IX.
Because of the risk of allergic reactions with factor
IX, your initial
treatment with Refixia® should be given in a medical clinic or in the presence of health care professionals where proper medical care for allergic reactions can be provided if needed.
Talk to your doctor immediately if your bleeding does not stop as expected or if you have to significantly increase the amount of Refixia® you need to stop a bleed. Your doctor will do a blood test to check if you have developed inhibitors (neutralising antibodies) against Refixia®. The risk for developing inhibitors is highest in people who have not been treated with factor
IX medicines
before, typically small children.
Blood clots
Tell your doctor, if any of the following apply to you as there is an increased risk of blood clots during treatment with Refixia®:
•
you have recently had surgery
•
you suffer from other serious illness e.g. liver disease, heart
disease, or cancer
•
you have risk factors for heart disease e.g high blood pressure,
obesity, or smoking.
Kidney disorder (nephrotic syndrome)
There is a rare risk of developing a specific kidney disorder called “nephrotic syndrome” following high doses of factor
IX in haemo
-philia B patients with factor
IX inhibitors and a history of allergic
reactions.
Catheter-related problems
If you have a central venous access device (CVAD), you may develop infections or blood clots at the site of the catheter.
Other medicines and Refixia®
Tell your doctor if you are taking, have recently taken or might take any other medicines.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using Refixia®.
Driving and using machines
Refixia® has no influence on the ability to drive and use machines.
Refixia® contains sodium
This medicine contains less than 1
mmol sodium (23 mg) per vial,
that is to say essentially “sodium-free”. In case of treatment with multiple vials, the total sodium content should be taken into consideration.
3.
How to use Refixia®
Treatment with Refixia® will be started by a doctor who is experi-enced in the care of patients with haemophilia B. Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure about how to use Refixia®.
Your doctor will calculate the right dose for you. The dose will depend on your weight and what the medicine is being used for.
Prevention of bleeding
The usual dose of Refixia® is 40
international units (IU) per kg of body weight. This is given as one injection every week. Your doctor may choose another dose or change how often the injections should be given, based on your need.
Treatment of bleeding
The usual dose of Refixia® is 40
international units (IU) per kg of body weight. Depending on the location and the severity of bleed-ing you may need a higher dose (80
IU per kg) or extra injections.
Discuss with your doctor the dose and number of injections you need.
Use in children and adolescents
Refixia® can be used in children and adolescents of all ages. The dose in children and adolescents is also calculated according to body weight and is the same dose as for adults.
How Refixia® is given
Refixia® is available as powder and solvent that is made up into a solution (reconstitution) and given as an injection into a vein. See “Instructions on how to use Refixia®” for more information.
If you use more Refixia® than you should
If you use more Refixia® than you should, contact your doctor.
If you have to significantly increase the amount of Refixia® you need to stop a bleed, talk to your doctor immediately. For further information, see section 2 “Allergic reactions and development of inhibitors”.
If you forget to use Refixia®
If you forget a dose, inject the missed dose as soon as you remember. Do not inject a double dose to make up for a forgotten dose. If you are in doubt contact your doctor.
If you stop using Refixia®
If you stop using Refixia® you may no longer be protected against bleeding or a current bleed may not stop. Do not stop using Refixia® without talking to your doctor.
If you have any further questions on the use of this medicine, ask your doctor.
4.

Instructions on how to use Refixia®
Read these instructions carefully before using Refixia®.
Refixia® is supplied as a powder. Before injection a solution must be made up (reconstituted) with the solvent supplied in the syringe. The solvent is a histidine solution. The reconstituted solution must be injected into a vein (intravenous (IV) injection). The equipment in this package is designed to reconstitute and inject Refixia®.
You will also need an infusion set (tubing and butterfly needle), sterile alcohol swabs, gauze pads and plasters. These items are not included in the Refixia® package.
Do not use the equipment without proper training from your doctor or nurse.
Always wash your hands and ensure that the area around you is clean.
When you prepare and inject medicine directly into the veins, it is important to use a clean and germ-free (aseptic) technique. Incorrect technique can introduce germs that can infect the blood.
Do not open the equipment until you are ready to use it.
Do not use the equipment if it has been dropped, or if it is damaged. Use a new package instead.
Do not use the equipment if it has expired. Use a new package instead. The expiry date is printed on the outer carton, on the vial, on the vial adapter, and on the pre-filled syringe.
Do not use the equipment if you suspect it is contaminated. Use a new package instead.
Do not dispose of any of the items until after you have injected the reconstituted solution.
The equipment is for single use only.

If your dose requires more than one vial, repeat steps A to J with additional vials, vial adapters and pre-filled syringes until you have reached your required dose.
5.
Inject the reconstituted solution
Refixia® is now ready to inject into your vein.
•
Inject the reconstituted solution as instructed by your doctor or nurse.
•
Inject slowly over 1 to 3 minutes.
•
Do not mix Refixia® with any other intravenous infusions or medicines.
Injecting Refixia® via needleless connectors for intravenous (IV) catheters
Caution: The pre-filled syringe is made of glass and is designed to be compatible with standard luer-lock connections. Some needleless connectors with an internal spike are incompatible with the pre-filled syringe. This incompatibility may prevent administration of the medicine and/or result in damage to the needleless connector.
Injecting the solution via a central venous access device (CVAD) such as a central venous catheter or a subcutaneous port:
•
Use a clean and germ-free (aseptic) technique. Follow the instructions for proper use for your connector and CVAD in consultation with your doctor or nurse.
•
Injecting into a CVAD may require using a sterile 10 ml plastic syringe for withdrawal of the reconstituted solution. This should be done right after step J.
•
If the CVAD line needs to be flushed before or after Refixia® injection, use sodium chloride 9
mg/ml solution for injection.
Refixia® is recommended to be used immediately after it has been reconstituted. This is because if left, the medicine may no longer be sterile and could cause infections.
If you cannot use the reconstituted Refixia® solution immediately, it should be used within 4
hours when stored at
room temperature (up to 30 °C) and within 24
hours when
stored in a refrigerator (2 °C – 8 °C). Store the reconstituted product in the vial.
Do not freeze reconstituted Refixia® solution or store it in syringes.
Keep reconstituted Refixia® solution out of direct light.
Scale
•
Unscrew the vial adapter with the vial.
•
Do not touch the syringe
tip. If you touch the syringe tip, germs from your fingers can be transferred.
