1. What AFSTYLA is and what it is used for

AFSTYLA is a human clotting (coagulation) factor VIII product that is produced by recombinant DNA technology. The active substance in AFSTYLA is lonoctocog alfa.

AFSTYLA is used to treat and prevent bleeding episodes in patients with haemophilia A (inborn factor VIII deficiency). Factor VIII is a protein needed for blood to clot. Patients with haemophilia A lack this factor, so blood does not clot as quickly as it should and they have an increased tendency to bleed. AFSTYLA works by replacing the missing factor VIII in haemophilia A patients enabling their blood to clot normally.

AFSTYLA can be used for all age groups.

2. What you need to know before you or your child use AFSTYLA

Do not use AFSTYLA

  • if the AFSTYLA patient had an allergic reaction to AFSTYLA, or any of its ingredients (listed in section 6).
  • if the AFSTYLA patient is allergic to hamster proteins.

Warnings and precautions

Traceability

It is important to keep a record of the batch number of your AFSTYLA.

So, every time you get a new package of AFSTYLA, note down the date and the batch number (which is on the packaging after “Lot”) and keep this information in a safe place.

Talk to your doctor, pharmacist or nurse before using AFSTYLA.

  • Allergic (hypersensitivity) reactions are possible. The product contain traces of hamster proteins

(see also “Do not use AFSTYLA”). If symptoms of allergic reactions occur, stop using the medicine immediately and contact your doctor. Your doctor should inform you of the early signs of allergic reactions. These include hives, generalised skin rash, tightness of the chest, wheezing, fall in blood pressure and anaphylaxis (a serious allergic reaction that causes severe difficulty in breathing, and dizziness).

  • The formation of inhibitors (antibodies) is a known complication that can occur during treatment with all Factor VIII medicines. These inhibitors, especially at high levels, stop the treatment working properly. You or your child will be monitored carefully for the development of inhibitors. If you or your child's bleeding is not being controlled with AFSTYLA, tell your doctor immediately.
  • If you or your child have been told you have heart disease or are at risk for heart disease, tell your doctor or pharmacist.
  • If a central venous access device (CVAD) is used for injection of AFSTYLA, the risk of complications including local infections, bacteria in the blood (bacteremia) and the formation of a blood clot (thrombosis) in the blood vessel where it is inserted should be considered by your doctor and discussed with you.

Other medicines and AFSTYLA

Tell your doctor or pharmacist 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 or pharmacist for advice before taking this medicine.
  • During pregnancy and breast-feeding, AFSTYLA should be given only if it is clearly needed.

Driving and using machines

AFSTYLA does not affect your ability to drive and use machines.

AFSTYLA contains sodium

AFSTYLA contains up to 35.0 mg sodium (main component of cooking/table salt) in each vial. This is equivalent to 1.8% of the recommended maximum daily dietary intake of sodium for an adult.

3. How to use AFSTYLA

Your treatment should be monitored by a doctor who is experienced in the treatment of blood clotting disorders.

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

Dose

The amount of AFSTYLA you or your child need to take and the duration of treatment depend on:

  • the severity of your disease
  • the site and intensity of the bleeding
  • your clinical condition and response
  • your body weight

Follow the directions given to you by your doctor.

Reconstitution and administration

General instructions

  • The powder must be mixed with the solvent (liquid) and withdrawn from the vial under aseptic conditions.
  • AFSTYLA must not be mixed with other medicines or solvents except those mentioned in section 6.
  • The solution should be clear or slightly opalescent, yellow to colourless, i.e., it might be sparkling when held up to the light but must not contain any obvious particles. After filtering or withdrawal (see below) the solution should be checked again, before it is used. Do not use the solution if it is visibly cloudy or if it contains flakes or particles.
  • Any unused product or waste material should be disposed of in accordance with local requirements and as instructed by your doctor.

Reconstitution and administration

Without opening the vials, ensure the AFSTYLA powder and the liquid is at room or body temperature. This can be done either by leaving the vials at room temperature for about an hour, or by holding them in your hands for a few minutes.

Do not expose the vials to direct heat. The vials must not be heated above body temperature (37 °C).

Carefully remove the protective caps from the vials, and clean the exposed rubber stoppers with an alcohol swab. Allow the vials to dry before opening the Mix2Vial package (which contains the filter transfer device), then follow the instructions given below.

Use the venipuncture kit supplied with the product, insert the needle into a vein. Let blood flow back to the end of the tube. Attach the syringe to the threaded, locking end of the venipuncture kit. Inject the reconstituted solution slowly (as comfortable for you, up to a maximum of 10 ml/min) into the vein following the instructions given to you by your doctor. Take care not to get any blood in the syringe containing the product.

Check yourself for any side effects that might happen straight away. If you have any side effects that might be related to the administration of AFSTYLA, the injection should be stopped (see also section 2).

If you use more AFSTYLA than you should

If you have injected more AFSTYLA than you should, please inform your doctor.

If you forget to use AFSTYLA

Do not take a double dose to make up for a forgotten dose. Proceed with the next dose immediately and continue as advised by your doctor.

If you stop using AFSTYLA
