What it is and what it is used for

for

Waylivra contains the active substance volanesorsen, which helps to treat a condition called familial chylomicronemia syndrome (FCS). FCS is a genetic disease which gives rise to abnormally high levels of fats called triglycerides in the blood. This can lead to inflammation of your pancreas, causing severe pain. Together with a controlled low-fat diet, Waylivra helps to lower the levels of triglycerides in your blood. Waylivra may be given after you have already received other medicines used to lower the levels of triglycerides in blood without them having much effect. You will only be given Waylivra if genetic testing has confirmed you have FCS and your risk for pancreatitis is considered very high.. You should continue the very low-fat diet that your doctor has prescribed during treatment with Waylivra. This medicine is intended for patients aged 18 years and above. 2.

Instructions for use Waylivra is an injection given under the skin with a single-use, disposable, pre-filled syringe. Do not use Waylivra until you completely understand the procedure described below. If you have any questions about how to use Waylivra, please contact your doctor or pharmacist. Pre-filled syringe components

Get ready to inject 1. Wash hands and gather supplies Wash your hands thoroughly with soap (for at least 3 minutes) and dry them well. Place the following items on a clean, flat surface in a well-lit area (Figure A).

Figure A 2. Allow the injection to reach to room temperature

If the syringe was in the refrigerator, allow the prefilled syringe to reach room temperature by removing it from the refrigerator at least 30 minutes before the injection. Injection with cold liquid may cause injection site reactions such as pain, redness, or swelling. Do not warm syringe in any other way, such as by microwave or warm water. Figure B 3. Check the expiry date Check the expiry date on the carton. The expiry date on the package refers to the life of the medicine when refrigerated. The date you first remove the pack from the refrigerator should be recorded on the outer carton in the space indicated. Do not use Waylivra if the expiry date has passed or if it was stored for longer than 6 weeks at room temperature. Call your doctor or pharmacist to get a new supply. 4. Remove the syringe and inspect the medicine Open the carton and remove the syringe by grasping the syringe barrel and pulling it straight out (Figure C).

Figure C Look at the liquid in the syringe. The medicine should be clear to slightly yellow in colour. It is normal to see a large air bubble (Figure D). Do not try to remove the air bubble before injecting. Injecting the solution with the air bubble is harmless. Do not use the pre-filled syringe if the liquid is cloudy or has floating particles. Figure D 5. Choose an injection site

If self-injecting: Stomach – Stomach area as shown, except for 2 inches around the belly button. Thighs – Front, middle area as shown (Figure E).

If administering an injection to someone else as a caregiver, in addition to the above sites:

Figure E

Arms – Back of upper area as shown (Figure F). For all injections: Alternate the injection area for each injection. Avoid injecting at the waistline where your clothing may rub or press the injection area.

Figure F

Do not inject into tattoos, moles, scars, birthmarks, bruises, rashes, or areas where the skin is tender, red, hard, damaged, burned, or inflamed. Talk to your healthcare provider if you are unsure of where to inject. Injecting 6. Prepare injection site Clean your chosen injection site with an alcohol pad (Figure G).

Figure G 7. Remove needle cap Remove the needle cap by holding the barrel of the syringe with the needle pointing away from you and pulling the needle cap straight off (Figure H).

You may see a drop of liquid at the tip of the needle. This is normal. Do not hold the plunger rod or the plunger head while removing the needle cap. Do not use the pre-filled syringe if the needle appears damaged. Do not use the pre-filled syringe if it is dropped with the needle cap removed. Figure H 8. Pinch the skin Using your free hand, pinch the skin around the injection site (Figure I).

Figure I 9. Insert needle Insert the needle into the injection site with a quick, firm motion without touching the plunger head. The needle should be inserted at a 45 degree angle to the skin surface (Figure J).

Figure J 10. Inject Waylivra Inject the liquid by holding the syringe with your thumb on the plunger, and slowly push the plunger down as far as it will go, until the syringe is completely empty (Figure K and L).

Figure K

Figure L 11. Remove Needle Remove the needle from the injection site by pulling out at the same angle it was inserted (Figure M).

Figure M After the Injection 12. Dispose of the Used Syringe into a Sharps Container Immediately after the injection, dispose of the used syringe as instructed by your healthcare professional, usually into a sharps disposal container (Figure N) by following these steps. Throw away the needle cap after injecting. Do not recap the syringe. If you do not have a sharps disposal container, you may use a household container that is:

Figure N

• Made of heavy-duty plastic,
• Capable of being closed with a tight-fitting, Puncture-resistant lid, without sharps being able to come out,
• Upright and stable during use,
• Leak-resistant,
• Properly labeled to warn of hazardous waste inside the container. When your sharps disposal container is almost full, you will need to follow your community guidelines for proper disposal of the sharps container. There may be special local laws regarding how you should throw away used needles and syringes. Ask your pharmacist or see your local

public health government website (where available) for more details on how you should dispose of sharps in your location. Do not dispose of your used sharps disposal container in your household waste. Do not recycle your used sharps disposal container. Always keep your sharps container away from children and pets. 13. Treat the Injection Site If you see blood where you've injected, press the site lightly with the sterile cotton ball or gauze and bandage if needed (Figure O). Do not rub the site after you've injected.

You may also apply ice to the injection site to reduce pain, redness, or discomfort (Figure P).

Figure O

During this 6 week period, this medicine can be stored at either room temperature or put back in the refrigerator. Do not freeze the Waylivra pre-filled syringe. Do not take out of the packaging or remove the needle cap until you are ready to inject. Discard this medicine immediately if not used within the 6 weeks after the first time it is removed from the refrigerator. You should refer to the date you have written on the carton to be sure.
