Read all of this leaflet carefully before you start using this medicine because it contains important information for you.


Tell your doctor, if any of the above applies to you.


Warnings and precautions


Talk to your doctor before using Extavia:


- If you have monoclonal gammopathy. This is a disorder of the immune system where an abnormal protein is found in the blood. Problems with your small blood vessels (capillaries) may develop (systemic capillary leak syndrome) when using medicines like Extavia. This can lead to shock (collapse) and even be fatal.



- If you have severe kidney problems, your doctor may monitor your kidney function during treatment.


- If you have ever had an allergic reaction to latex. The tip cap of the pre-filled syringe contains a derivative of natural rubber latex. Therefore, the tip cap may contain natural rubber latex.

Your doctor also needs to know the following whilst you are using Extavia:




- If you experience symptoms such as irregular heartbeat, swelling such as of the ankles or legs, or shortness of breath. This may suggest a disease of the heart muscle (cardiomyopathy) which has been reported in patients using Extavia.


- If you notice pain in your belly which is radiating to your back, and/or you feel sick or have a fever. This may suggest an inflammation of the pancreas (pancreatitis), which has been reported with Extavia use. This is often associated with an increase in certain blood fats (triglycerides).


Stop using Extavia and tell your doctor immediately if any of these happens to you.

Other things to consider when using Extavia:



  1. Getting ready to inject


    • Choosing an injection site


      Before preparing your injection, decide where you are going to inject. You should inject this medicine into the fatty layer between the skin and muscle (that is, subcutaneously, about 8 mm to 12 mm under the skin). The best places for injections are where the skin is loose and soft, and away from joints, nerves and bones, for example the abdomen, arm, thigh or buttocks.


      Important:


      The tip cap of the pre-filled syringe contains a derivative of natural rubber latex. Therefore, the tip cap may contain natural rubber latex. If you are allergic to latex, talk to your doctor before using Extavia.


      Do not use any area where you can feel lumps, bumps, firm knots, pain or an area that is discoloured, indented, scabbed, or where the skin is broken. Talk to your doctor or nurse about these or any other unusual conditions you may find.


      You should rotate the injection site at every injection. If some areas are too difficult for you to reach, you may need a family member or friend to help you with these injections. Follow the sequence described in the schedule at the end of the Annex (see Part II “Rotating injection sites”) and you will come back to your first injection site area after 8 injections (16 days). This will give each injection site a chance to fully recover before receiving another injection.


      Please refer to the rotation schedule at the end of this Annex to learn how to choose an injection site. An example of a medication record is also included (see Annex Part III). This should give you an idea of how you can keep track of your injection sites and dates.


    • Medicine


      You will need the medicine:

      • 1 Extavia vial (with powder for solution for injection)

      • 1 pre-filled syringe of solvent for Extavia (sodium chloride solution)


        To reconstitute and inject your medicine you will need to use an ExtaviPro 30G application kit (supplied separately to your medicine), which contains the following components and instructions on how to use them:

      • Vial adapters for use when reconstituting your medicine

      • 30-gauge needles for injecting your medicine

      • Alcohol swabs


    You will also need a disposal unit for used syringes and needles.


    The 30-gauge needles provided with the application kit for the administration of this medicine can be used either for manual injection OR with an ExtaviPro 30G auto-injector.


    For skin disinfection use an appropriate disinfectant recommended by your pharmacist.

  2. Reconstituting and drawing up the solution for injection, step by step


    image

    1. - Wash your hands thoroughly with soap and water before beginning this process.


    2. - Remove the flip off cap from the Extavia vial. It is best to use your thumb rather than your nail, as your nail could break. Put the vial on the table.


    3. - Clean the top of the vial with an alcohol swab, moving the swab in one direction only. Leave the swab on top of the vial.


    4. - Peel back and remove the cover from the vial adapter packaging.

      Do not remove the vial adapter from its packaging.


    5. - Remove the swab from the top of the vial.

      Use the packaging to handle the vial adapter. Attach it to the vial by pushing down until the vial adapter penetrates and locks around the top of the vial.


    6. - Holding the edges securely, remove and discard the packaging

      ensuring the vial adapter remains on the vial.

      image

    7. - Take out the pre-filled solvent syringe from its package. Snap off and discard the tip of the syringe.

      Note: Be careful not to touch the exposed end of the syringe. Do not push the plunger.


    8. - Holding the vial and adapter securely, screw the syringe fully onto the vial adapter.

      This forms the syringe-vial assembly.


    9. - Hold the syringe-vial assembly at a slight angle. Push the plunger down slowly so that the liquid runs down the inside of the vial. Transfer all the solvent to the vial.

      Note: Do not shake the vial as this may cause excessive foaming.


    10. - Hold the vial between your thumb and fingers. Swirl the syringe- vial assembly gently until the powder is completely dissolved.

      Note: Do not shake the vial.


    11. - Examine the solution carefully. It should be clear and contain no particles.

      Note: If the solution is discoloured or contains particles, discard it and

      start again with a new syringe and vial from your package.

      If excessive foaming is present – which can happen if the vial is shaken or swirled too vigorously – let the vial sit undisturbed until the

      foam settles.


    12. - Ensure the plunger stays fully pushed in before proceeding to the next step, as it may have moved.


    13. - Turn the syringe-vial-assembly so that the vial is at the top. Slowly pull the plunger back to draw all of the solution into the syringe.

      image

    14. - Remove any excess air bubbles by gently tapping the syringe. Push the plunger to the 1 ml mark (or to the volume prescribed by your doctor).

      Note: It may be necessary to adjust the plunger position back and forth a few times to ensure the excess air bubbles are gone and there is 1 ml

      of solution in the syringe.


    15. - Unscrew the syringe, leaving the vial adapter on the vial. Dispose of the vial and the remaining unused portion of the solution into the disposal unit.


    16. - Take the needle out of its wrapping and screw it firmly onto the top of the syringe.


    17. - Leave the needle cap on. You are now ready to manually inject yourself or to use the ExtaviPro 30G auto-injector for the administration of Extavia.


      Storage after reconstitution

      If, for some reason, you are not able to inject Extavia immediately, you can refrigerate the reconstituted solution for up to 3 hours before using it. Do not freeze the solution, and do not wait longer than 3 hours to inject it. If more than 3 hours pass, discard the medicine and prepare a

      new injection. When you use the solution, warm it up by holding the syringe or vial in your hands before injecting to avoid pain.

  3. Making the injection manually (to make an injection with the ExtaviPro 30G auto- injector, refer to the instructions for use provided with the auto-injector)


  1. - Choose a site for the injection (refer to the section “Choosing an injection site” and the diagrams at the end of this leaflet) and make a note of it in your medication record.


    image

  2. - Use an alcohol swab to clean the skin at the injection site. Let the skin air-dry. Throw the swab away.


  3. - Remove the cap from the needle by pulling and not twisting it.


    image

  4. - Where possible gently pinch the skin together around the disinfected injection site (to raise it up a little).


  5. - Holding the syringe like a pencil or a dart, push the needle straight into the skin at a 90˚ angle with a quick, firm motion.


  6. - Inject the medicine (by pushing the plunger slowly and steadily all the way in until the syringe is empty).


  7. - Discard the syringe in the disposal unit.

PART II: ROTATING INJECTION SITES


You need to choose a new site for each injection to allow the area time to recover and help prevent infection. Advice on which areas to choose is given in the first part of this Annex. It is a good idea to know where you plan to inject before you prepare your syringe. The schedule shown in the diagram below will help you to vary the sites appropriately. For example, give the first injection into the right side of the abdomen, choose the left side for the second injection, then move to the right thigh for the third, and so on through the diagram until all suitable areas of the body have been used. Keep a record of where and when you last gave yourself an injection. One way to do that is to note the injection site on the enclosed medication record card.


By following this schedule, you will come back to your first area (e.g. the right side of the abdomen) after 8 injections (16 days). This is called a Rotation Cycle. On our example schedule each area is split again into 6 injection sites (which adds up to 48 injection sites altogether), left and right: upper, middle and lower part of each area. If you come back to an area after one Rotation Cycle choose the most distant injection site within this area. If an area becomes sore, talk to your doctor or nurse about choosing other injection sites.


Rotation schedule

To help you rotate the injection sites appropriately, we recommend that you keep a record of the date and location of your injection. You can use the following rotation schedule.


Work through each rotation cycle in turn. Each cycle will be 8 injections (16 days), given in area 1 through to area 8 in turn. By following this sequence, you will give each area a chance to recover before receiving another injection.


Rotation Cycle 1: Upper left section of each area Rotation Cycle 2: Lower right section of each area Rotation Cycle 3: Middle left section of each area Rotation Cycle 4 Upper right section of each area Rotation Cycle 5: Lower left section of each area Rotation Cycle 6: Middle right section of each area
